Displaylink driver 8.0 M.0 Mouse & Keyboard Lag
 

My mouse & keyboard lag heavily after I install Displaylink driver 8.0, same thing happened with previous 8.0 beta driver.

Reverting the driver to 7.9 solve the issue but windows update automatically updating the driver to 8.0

Using Dell USB 3.0 dock D3000, dell XPS 12 9Q33

Monitor connected using DVI port

Hello,
We have not observed noticeable lag during normal office use of the new driver.
However, we have tasks pending to improve the performance (we use automated software to detect actual frame rate, not humans).
It might be useful if you could describe what the computer is doing and if there is anything abnormal as it may be something else going wrong with the driver.

As you get 8.0 from Windows Update, you must be in the Windows Insiders program (WIP) and use the new Windows 10.
There are fundamental changes coming in the new Windows 10. One of these change allows native DisplayLink USB graphics support in the OS.
The other one is an upgrade of the graphics drivers expected mid-August making them incompatible with 7.9. Should you run 7.9 when these changes arrive, you will be hit with at best a rain of blue screens and at worse an unusable computer. That's why Microsoft put 8.0 as critical on the WIP. All 7.9 versions will be unavailable for Windows 10 builds above 10586.

Kind regards,
Alban

Is the mid august drivers for graphics coming from your company or from Intel/AMD/Nvidia? Wasn't sure. And do you recommend to go to the new windows 10 anniversary update as soon as it comes out? I am currently running the insider preview.

The change of graphics version is coming from Intel/AMD/Nvidia.
We will have a new driver as well, to fix a few things. I expect to put the 8.0 M1 driver on our website the week starting the 8th August.

If you use the Fast Ring Insiders, you will be using something almost identical to the Anniversary Update already. For the graphics point of view, I would not expect differences between the release version and the build 14393 you are likely to be using now.

mouse & keyboard not really lag, it is non-responsive
 

have to reword, it is not lag.
Mouse & keyboard is often non-responsive. I will have to click the keyboard to make mouse move again.

Seems the USB display is interfering with USB interface for other device, even if I connect mouse direct to my laptop USB, the non-responsive mouse is recurring if i use USB display.

Hello,

The OS doesn't allow drivers to talk to each other or intercept the traffic from other USB devices not even connected to it.
Trying to access another process's memory would crash the driver.

If the issue is only with the mouse, and only in Replace mode, we have fed this back to Microsoft as this is an OS issue. Are you in Extend?
I suggest you also report to them as feedback from customers is always more powerful than from partners.

Kind regards,
Alban

lagging issues after resume from standby
 

There are definitely problems concerning the new DisplayLink driver. After resuming from standby I sometimes encounter severe lagging in Win 10 1607.
I can't see any special when looking at task manager stats - neither cpu cycles, nor E/A show anything suspicious. The whole system is nearly unresponsive, typing and clicking, switching programs - everything.
As soon as I unplug my USB monitors, everything is immediately back to normal. Re-plugging is fine.

Stepinsky, what DisplayLink driver version do you use?
I'm sorry but you don't really give me much to work on...

I think you should try to update to 8.0 M1 (8.0.629.0), I've posted on the website today.
Your issue rings a bell: it all becomes sluggish after resume from sleep because of some timeout issues.

integrated drivers or separate install?
 

Sorry for the late reply. I had some issues posting to this forum.

When upgrading to 1607 my M8 driver was removed. Then I read this response:
On my machine (Lenovo W530) Windows automatically installed a new driver. Because you mentioned the driver is now OS integrated, I didn't care about the driver version in my post above. Actually it was version 8.0.478.0. Yesterday I tried 8.0M1. I will post my experiences with this driver.

That response is not from DisplayLink and is factually wrong as I commented on the thread.
It has nothing to do with compatibility. Nothing is broken. DLM is removed on purpose because it is superfluous!

If your issue persist on 8.0 M1, you can attach your logs so we can look at them and the mode (replace, extend...) you use. My forum signature states how.

Hi,

There is definitely significant mouse and keyboard lag associated with the DisplayLink drivers on the anniversary edition. After uninstalling the drivers, the lag goes away (I used the clean removal tool).

When I re-install, it comes right back. The lag only applies to inputs using DisplayLink - I don't have this issue with USB mice attached separately or my laptop's native keyboard.

There is also video lag, though that is harder to demonstrate. The screen does not redraw at the right pace, causing visual artifacts to appear frequently. It makes the machine very hard to use, and again, I've been able to successfully repro this specifically with the DisplayLink drivers.

I'm using the anniversary update with the newest available drivers.

I wanted to start a new thread but since this one quite fitst I'll write it here.

I use Dell E5550 notebook just got the Dell D1000 dock for it.
The OS is Windows 10 64-bit Anniversary edition (version 1607, build 14393.51)
I've got one monitor (vi HDMI), mouse, keyboard and LAN connected to the dock.

First I installed the driver from here:
http://www.dell.com/support/home/us/...-d1000/drivers
The link to the file (if the current one is later replaced by newer version):
http://downloads.dell.com/FOLDER0372...-47MTD_ZPE.exe
The driver version is claimed to be: 7.9.1612.0 and its release notes also mention it's the 7.9 M7 release, however 7.9 M7 drivers available at http://www.displaylink.com/downloads/windows are 7.9.1589.0 so this may be something like a Dell specific version, or just some minor update within the 7.9 M7 release.

Installation complained that my Windows version is not compatible etc, but I let it continue and see how it goes.
After the installation completed I was told to connect the dock so I did that, it was recognized etc, the external monitor went on and it was possible to finalize the setup. So far so good.
However shortly afterwards the external display went off and it was obvious something strange was happening. Later I found it was because the Windows decided to update the drivers from Windows Update - but more on that later. I restarted the OS after some time and everything seemed to work again.

However there was noticeable lag at the beginning of mouse cursor movements (not all, just some, like in 20% of cases or so) and also similar lag on displaying the input from the keyboard. That was quite annoying so I tried to look for some possible solutions.

I tried tips from here: http://support.displaylink.com/knowl...ncy-desktop-pi but nothing of that helped. I also found some other tips elsewhere but none of them helped either. Then I started to experiment with different drivers because when I had that version 7.9.1612.0 from the Dell website installed for a while (before it was replaced with some version 8.0 from Windows Update) it didn't seem to lag.

First I tried the 8.0 M1 from http://www.displaylink.com/downloads/windows but it was lagging as well and it was also quickly replaced with different 8.0 from Windows Update.

Then I tried the 7.9.1612.0 from the Dell website again and it didn't really lag, but Windows again replaced it with 8.0 from Windows Update.

So it seemed the 7.9.1612.0 would be the best one for now (despite it not being declared fully compatible with Windows 10 Anniversary update), but the problem was how to prevent the Windows Update from replacing it..

Naturally I started here: https://support.microsoft.com/en-us/kb/3073930

First I tried to roll back the driver for all relevant devices that I found in the device manager (display driver, network adapter, sound driver). I could do that and that got the to the right versions, but unfortunately the external display didn't work after that (the display adapter was "working properly" but the display wasn't detected).

Next I tried the "Show or hide updates" troubleshooter. After some hassle (I had to be quick because Windows was able to replace the driver very quickly and hiding that update after the driver roll back didn't work for a new driver install) I managed to hide the "DisplayLink driver update for DisplayLink USB Device" update so the display driver stopped being silently updated. However the DisplayLink drivers update (at Windows Update) seems to consist of at least 2 parts - the 1st one that I just mentioned and the 2nd one for sound and ethernet devices and the problem is that the 2nd one never appeared anywhere and therefore I was unable to block it via the "Show or hide updates" troubleshooter. Simply those drivers were still being silently updated regrdless of the "DisplayLink driver update for DisplayLink USB Device" being already blocked. As a result when the display driver was at version 7.9 and the sound and ethernet drivers were then updated to version 8.0 the external display didn't work again.

Because I was dealing with another "silent driver update" case previously, I did know that Windows first downloads those driver packages to C:\Windows\SoftwareDistribution\Download\ then unpacks them and performs the driver update - so I went to that directory, deleted all of its contents, recreated the issue with the silent driver update again and noted all files and directories created there. Then I created empty files with the same names in there, removed write permissions for system on them, reinstalled the 7.9.1612.0 drivers cleanly again and that finally seemed to do the trick - now all drivers stay at that version 7.9 and there's really no lag finally. However I'm afraid that once some updated drivers are offered via Windows Update they will be silently replaced again.

So long story short:

- with Windows 10 64-bit Anniversary update
- all current 8.0 drivers lag for me
- the 7.9.1612.0 driver from the Dell website doesn't lag
- Windows Update is a nightmare with its silent driver updates in Windows 10, you have to put really a lot of effort into blocking it sometimes as even the "Show or hide updates" troubleshooter isn't able to catch all such updates and "roll back driver" isn't also always the way to go

Note that I'm not sure which version of drivers does Windows Update currently offer (I'm just happy to finally get rid of it - at least for now), but those version numbers were slightly lower than those of the 8.0 M1, so it might be 8.0 M0 or so.

Hope this helps

Hello,
There is a very good reason why the audio and Ethernet drivers are packaged with the rest. If versions don't match then things can't talk to each other...
The version 7.9.1612.0, is the package build, not the version of the driver it includes. Manufacturers like Dell decides of options they want in the docks they make, and the branding of the installer. That's why the package build number is different than the generic package you have from our site. Inside is the same: 7.9.1589.0 USB driver and host software (you can look at the release notes).

You mention "connecting a mouse to DisplayLink". This is impossible physically. DisplayLink chip cannot host devices. You connect your mouse to a USB hub in the dock. That USB hub is not DisplayLink. The DisplayLink chip is also connected to that hub. DisplayLink does not make any hub, adapter or dock, and DisplayLink driver cannot command the USB hub, or any device connected to it because Windows decides the driver to use based on the device I'd.
Should you decide to keep 7.9 M7, you will get severe failures when the new Intel/nvidia graphics driver are pushed to your machine. This is a promise, we and Microsoft have tested. You may not be able to login.
The help documentation is not really relevant to Redstone builds. As we use native OS support, we are limited by what we can do compared to before.

Are you in Replace, Clone or Extended desktop?
There is a Windows bug in Replace mode: Windows puts the graphics card to bed so it stops calculating pixels. The OS still uses the graphics card to compute the pixels to send to DisplayLink.
Can you reproduce the issue after uninstalling the primary graphics card driver and using the Microsoft Basic Graphics inbox driver?
What applications are running when you have the issue?
Is the issue addressed by a dock replug?
Is the D1000 connected in USB2 or USB 3?

I'm asking these questions to understand the root cause as we haven't noticed that yet and we need to get it to debug it... And I clearly don't get it , yet :)

We had a bug on recovery from sleep, this is fixed in 8.0.629.
If several versions of DL are installed at the same time (7.9 being installed over 8.0), they might have a duel.


Kind regards,
Alban

Alban, I get that you guys want to separate yourselves from these bugs since your hardware doesn't involve mouse inputs, but plain and simple the DisplayLink drivers are causing input lag on Win10 anniversary.

I'm using extended desktop, exact same set up as I was using prior to Win10 anniversary, except when I'm connected through DisplayLink my inputs are laggy, just as the others on this thread are commenting on.

Glad to provide you with any diag information you may need.

EDIT: Wait a minute, you guys totally do offer drivers for the USB docking station I'm using: http://plugable.com/drivers/displaylink

These drivers need an update.

AlbanRampon: so I've done some more tests:

First as I tried to keep the drivers installation as clean as possible I always uninstalled drivers the following way:
- In Device Manager: uninstalled the display and ethernet adapters and sound controller from the dock device with the option "Delete the driver software for this device"
- In Device Manager: uninstalled the external keyboard and mouse as well
- disconnected the dock
- for the standalone driver packages (either from Your or Dell website) I also uninstalled the software from Programs and Features
- restarted
- run the DisplayLink Installation Cleaner
- restarted

From this state, I tested the following 3 driver packages, one by one (each one always from this "clean" state):
1. 7.9 M7 from Dell (Dock_DL_Win_A00_Setup-47MTD_ZPE.exe) with Windows Update drivers blocked
2. 8.0 M1 from Your website (DisplayLink USB Graphics Software for Windows 8.0 M1.exe) with Windows Update drivers blocked
3. 8.0 M0 (most likely) from Windows Update (installed by just connecting the dock and waiting for the drivers to install from Windows Update automatically

Both those 8.0 drivers did behave identically regarding the lag so I won't mention them separately in the following text.

1. Replace display mode (Show only on 2):
- 7.9 M7: no lag
- 8.0: lag

2. Extend display mode:
- 7.9 M7: no lag
- 8.0: no lag (the only case when the 8.0 drivers didn't exhibit that lag)

3. In Replace display mode, disconnect & reconnect the dock at runtime:
- 7.9 M7: no lag
- 8.0: lag

4. In Replace display mode, disconnect mouse from dock & connect it directly to the laptop USB port:
- 7.9 M7: no lag
- 8.0: lag

5. In Replace display mode, use the laptop builtin touchpad instead of the USB mouse:
- 7.9 M7: no lag
- 8.0: lag

All these tests were performed after a full system restart, no sleep & resume, no user applications were running, I just logged in and moved the mouse and watched what happens.

Dock was always connected via the USB 3.0 connection - always the same USB port.

All devices are wired, no wireless mouse or anything like that.

Same as Above
 

I have a Lenovo X1 Carbon, with 2 DiplayLink adapter monitors connected. on e is connected with Display port other is connected via USB with Plugable card. Since the Anniversary update the USB monitor is DOOOOG slow, anything i drag to that screen moves like slow motion. Other screens are fine. Prior to the Anniversary update everything worked like a rock star!! Uncertain what happened in coordination - however i assure you this has significantly changed and not for the better.

Mag, thank you for the time you took to do all that. I know how you feel because your tests pretty much mirror mine, and with the same results. I am using a Plugable UD-3900 connected to a Dell XPS 9550. This problem is definitely driver and/or software (Windows + Updates) related.

The new drivers are definitely causing visual stuttering. The more there is happening on the screen the more consistent the lag gets, at least for me. I say visual because while the keyboard input will lag, the input does appear after a stutter. If the keyboard input itself were the lag then I think whatever was typed during the stutter would be lost. I could be wrong.

Windows Driver Foundation (WUDFHost.exe) appears to have something to do with this. CPU usage from it spikes when there is more going on such as video, cursor movement, or basically anything that is changing on the displays. I have tried disabling it in Services, but then the displays on the DisplayLink no longer work. Other devices continue to work without Windows Driver Foundation enabled, but the displays do not.

I disable Windows Updates anyway and will stick to 7.9 M7 until this issue is worked out.

D3000 Mouse Lag Issue - Ethernet adapter?
 

Hello all. User of Dell 3000's (one at home, one at work) for quite some time on a Dell XPS 9333, but first time on the forum, and no expert by any stretch.

I've been dealing with mouse lag since I updated to the Anniversary update. I'll get maybe a 1 second delay when moving my mouse, or a 1 second delay when scrolling. Doesn't happen all the time, but maybe 50% of the time. I haven't noticed anything with keyboard lag.

I only did this only about 20 minutes ago, but have not had an issue with mouse lag since. Maybe too soon to tell.

I disabled the Dell GigabitEthernet adapter and went strictly wifi. At least a temporary work around.

Update: Got home, turned off the Ethernet adapter as I did at work, and experiencing lag. No idea why the difference

Between your post and some questions that Plugable asked me, I realize I left out a couple details that could be helpful.

My setup: I have a Plugable UD-3900 at home and one at the office that I connect to with the XPS laptop. The setups are very similar. Same monitors, keyboards, and mice. The only difference is that at home I have a XBOX wired controller and a webcam both connected via the dock. And I do believe that, similar to what DougG said, the home computer experiences more lag/stutter than the office setup does.

In both setups there are monitors used in Extend mode, and the laptop display itself is set to Disconnected. My laptop does have dual graphics cards, but I have already tried disabling the dedicated to see if anything changes without success.

One (strange) way to duplicate this: Have the task manager open with CPU usage in descending order, and watch the Windows Driver Foundation usage while repeatedly tapping the Windows key. My usage goes up to around 20% easily and I’ll see very obvious mouse stuttering.

I've always had stuttering of some sort. It just wasn't noticeable under normal office and web use. But if I open a game such as Geometry Dash it was noticeable. Now it is completely unplayable of course as a 1-second stutter gets you killed. Maybe the updates (driver/Windows) are simply causing more CPU usage that results in the stuttering?

Von, I'm seeing exactly the same things you are seeing. I also have a dual graphics card system - are you using a Surface Book?

Alban - You can make excuses until the cows come home, but Mag is 100% accurate. I have spent far too many hours troubleshooting this problem thinking it was something other than DisplayLink, including having a Dell tech come out and go through my computer. As soon as I disconnect my mouse and monitors from the device that houses your DisplayLink chip, the problem completely goes away. I've done everything your troubleshooting says from disabling the Intel Thermal Framework and everything else you're trying to point a finger at, but in the end it is a DisplayLink problem, and it's as simple as that.

The problem is 100% related to both the new DisplayLink driver and Windows 10 Anniversary, and frankly it's driving me insane. I get a stutter/lag every few minutes for probably about a second, which NEVER happened before Windows 10 AU or before the last DisplayLink driver update. PLEASE get this fixed as soon as possible. It has to be one of the most irritating issues I have ever dealt with, having to constantly deal with a stutter/lag. For heaven's sake, it's not a coincidence that there are 10 people on this thread using different devices with the DisplayLink chip all having the same problem. Stop making excuses and fix the stupid problem.

Still getting major lag from this - it's affecting productivity in a big way. Is this something DisplayLink is looking at?

Mouse & Keyboard lags since Win10 Anniversary Update
 

Hello,
I am facing the same problem! Since the Win10 Anniversary Update I see many lags when using mouse and keyboard. I dont know if the lag comes from the input devices or from the video output (e.g. never checked if videos do lag also without input). I can also see high CPU load of "Windows Driver Foundation - Benutzermodus-Treiberframework-Hostprozess" ( WUDFHost.exe ) since the update. I already tried to completely uninstall the DisplayLink software using the cleaner tool and reinstall the latest 8.0 M1 software but still facing the same lags.

Never had any problem before the Win10 Anniversary Update.

My Setup:
Dell XPS 13 9350 (Service-Tag: J0KWL72)
Dell USB3.0 dock D3100
2 Monitors connected in extended mode (One via DisplayPort, One via HDMI)
Notebook Monitor closed while connected to the Dock

I always made all updates coming through the Dell Update and Dell Command Update software, so Drivers and Firmware should be up-to-date.

I really hope there quickly comes an update which eliminates these lags, as it is really annoying!

Best regards

EDIT: Just found the following answer of some DisplayLink-Technican
Hopefully this will fix the problem end of August...

I have exactly the same issue as BeLu on a Dell XPS13 and the lag is very annoying especially as this is my Work PC. Cannot wait for this update to resolve this. I have reduced CPU by wiping software off my PC but the lag is slowly increasing when CPU spikes.

I created an account just to confirm I'm having the same issues. Using a Dell e7450, after upgrading to Anniversary + 8.0 M1 mouse lag and stutter was immediately noticeable. I had no such issues with 7.9 M7 + Win10 1511.

I have provided my Displaylink troubleshooting ZIP in case it helps in any way.

Edit: I find it helps to leave the laptop lid open. Slight lag is still there but stutter is almost completely gone.

BeLu - Unfortunately, I think the tech you are quoting is referring to a different issue. Alban is the tech originally responding to this thread, but it seems he's given up - probably because he knows he is wrong, and doesn't know what else to say. I also hope the problem is fixed in M2, but I don't have a lot of hope since the techs now seem to be ignoring the issue.

Not really. If I really didn't care, I wouldn't have asked the questions...
But to solve an issue, one must first understand it. Thank you for providing the info, once I'm back in the office I will look into it.

John,

It's not about excuses, read the other threads before make a judgement.

Have you created the support case as advised everywhere (including all my posts) when something is absolutely urgent? If so can you give the ticket number so I can look at it when back in the office?
I understand you don't care, but I am entitled to take a sick leave when unwell, so I did.

I have asked questions to get a reproduction internally. Just repeating it lags has not really helped much. But knowing things like applications running, how the devices are connected would.
There could be different reasons resulting in the same symptom.
I never talked about Intel Thermal Framework as I don't see any relevance here. Are you sure you are reading the correct thread?

If someone told you that 8.0 M2 was solving this, you can ask for a 8.0 M2 release candidate through a support ticket to validate this. As I have been out of the office, I haven't read all tickets and all posts.

Regards,
Alban

Hello DaveTheBrave,

Thank you for including the log files.
I see USB communication issues between the dock and the host computer.
Would you please be able to create a support case by sending an email to Technical_Enquiries @ DisplayLink.com asking for 8.0 M2 Release Candidate and adding reference 23105? There is a change made in the code going in the dock (not the computer) which should hopefully remove the USB errors and allow us to see more clearly.

Kind regards,
Alban

Hey microdave,
Would you please be able to provide log files as described in my forum signature so I can look into it?
Kind regards,
Alban

Surface 2 / Mouse Keyboard Freez
 

I have terrible lags from Keyboard/Mouse more or less since the Windows 10 Anniversary update few weeks ago.

Surface 2
Windows 10 Annivesary Update
Display Logic Docking station - Targus ACP70EU USB 3.0 Super Speed Dual Video Docking Station
Tried different types of mouses and keyboards Bluetooh / USB
2 x DELL U2414H


It seems that plugging only on Screen on the Docking station and one other via Mini DVI make the lags happen less often.

Please update the drivers ASAP, those mouse freezing drive me crazy.

Alban,

I'm sorry you were sick. My concern is I just want to make sure this issue is being considered for 8.0 M2, as I have no idea when the next release will come out, and I can't continue to live with this problem for months on end. You don't need to try to prove you're right on this forum. Instead of wasting time trying to defend yourself, please just assist try to assist us with the problem so we can all (including yourself) work more effectively. I am having to work every day on a buggy system with a little stutter every couple of minutes and it is honestly about to drive me crazy.

I understand that requesting different configurations is helpful in troubleshooting a problem. My previous point was that I can list probably 10 different configurations in this thread (including at least one person with the exact same configuration as me), yet you respond by saying things like "You don't plug anything into DisplayLink", trying to point fingers at other people instead of just trying to help your customers solve the problem. Most others (if not all in this thread), including myself, also had NO issues with 7.9 and pre-Windows 10 AU. With this many reports and views on this thread (being one of the top viewed issues at the moment) under multiple different configurations, DisplayLink is obviously the root of the problem.

I never said that you said anything about uninstalling the Intel Thermal Framework. I was simply mentioning that I had done what DisplayLink suggested that I do, which is also on your general support page (maybe you should actually read your support page instead of telling me there is no relevance):

http://support.displaylink.com/knowl...ncy-desktop-pi

I've tried everything this particular page talks about. I've also spent HOURS researching the problem on the internet. I'm a computer guy, and I even had had a Dell tech come to my house and troubleshoot the problem after I couldn't get any further.

When I buy something, I think it's ok if I expect it to work. It shouldn't be my job to spend hours and hours trying to fix something, then only to be hassled by a support tech. This doesn't help me want to talk positively about your company or your products.

I have no idea whether 8.0 M2 will fix the problem. I certainly hope it does, but nothing on this forum makes me believe the problem is even being properly considered. I would love to test 8.0 M2, but only if you believe the problem has been addressed (at any level) in the new version. If you believe this is the case, please let me know what needs to happen to get the release candidate.

John,

Did I miss the log files or ticket you created?
Several of the others in this thread and other similar ones have created tickets and I have analyzed them and no, not all of them have the same root cause.

The lag when lid closed or in replace mode (= only monitors active are through DL) is a Redstone OS bug Microsoft not only accepted but verified fixed in a new OS build!
8.0 M2 won't fix that OS bug. Me working with manufacturers and users to show, with undeniable proof (like logs), that this issue is important will make that bug fixed through servicing before Redstone 2.

But I still don't know which issue you have, just symptoms.
Once I've seen logs collected when the issue was present, I'll be able to say if it's worth trying a new release, not before.

I am having exactly the same issues with John. The constant lag is unbearable. I also had NO issues with version 7.9 and pre-windows 10 AU. It's obviously an issue related with 8.0 M1 not an OS bug.

Brock,
Obviously you changed 2 things: new OS and driver architecture which uses a totally way of doing things which did not exist before AU.

Do you know you could have posted these logs with your post?

It's like phoning your doctor to argue (s)he's not solving your incessant coughing but not allowing him/her to see you or do any test...

I'm also having mouse lag issues and noticed that the WUDFHost.exe process is taking lots of CPU% constantly. (sometimes it spikes up to 20% and keeps on like that until I disconnect the USB dock from my laptop and re-connect). This started happening after downloading the Windows 10 Anniversary update.

This is affecting my productivity terribly as the mouse lag is very noticeable.

I've attached the support log files for your perusal.

Thanks,

Daniel

Screen lag after upgrading to M2 driver
 

Just upgraded to M2 with W10 Anniversary version. I do see a noticeable difference in screen lag: I've 2 screens connected using displaylink, on the 1920x1200 screen the lag is not there, on the 3440x1440 screen there's still a noticeable lag, although it's workable. This lag was not present with the 7.9 and previous windows 10 version, so there still seem to be a need for performance improvements with the anniversary update.

If it helps I can provide debug information, just let me know.

Hello Bert,
Could you tell me how you gauge the lag?
Is it whilst playing video when you notice an issue with lipsync or is it just the mouse pointer, or something else?
Kind regards,
Alban

Hi Killswitch,
I see you only have two monitors activated.
Can you please activate the third one, which is likely to be the onboard LCD monitor?
Our driver is looping, waiting for frames to display.
20% of CPU is not a lot, there are still 80% left... CPU usage is adaptative so it won't be using 20% if there's not enough CPU bandwidth available.
I guess you are only using external displays and are meeting the OS bug putting the graphics card to sleep. Activating all monitors should, surprisingly, make things better. If that doesn't work, can you please describe your setup?
Kind regards,
Alban

It's the mouse pointer and general screen refresh...it's a bit slower then it used to be...still workable though. Actually today performance seems to be better, so let me try a few more days first, maybe there's other factors in play.
