Very sluggish compared to Mountain Lion
 

My Apple menu is on the left instead of the right on my second monitor and the performance pales compared to mountain lion. Any Suggestions

To be more specific, the frame rate appears to be 4-5 frames a second on a samsung monitor at 2048x1152 where as I previously experienced ~30FPS. Should I expect this to improve as the beta matures or should I look for a different solution? Does anyone else have experience?

There is no question that DisplayLink on Mavericks is awful compared with Mountain Lion. I'm just about to upgrade to the 2.1 release and I'll let you know if anything gets any better...

So while still running Mavericks but now using the new 2.1 release I see improved performance i.e. not any where near as sluggish. Maybe it was the fact that I had to do a restart, but the outcome is that things are a lot less jerky. The main thing I wanted to see fixed (all the epilepsy inducing flashing in safari and mail) is still broken :-(.

I take that back - the main thing I wanted to see fixed was the fact that pieces of windows, or even whole windows don't even display at all unless you do something to make the DisplayLink stuff force a redraw of the display.

Well guess what - it's back to being really sluggish again. Safe to say I have no idea what's going on...

Agree
 

Still sluggish. Anyone with experience on DP8?

We are aware performance is slower on 10.9, even though we are using exactly the same Apple API to get the pixels. We're looking into if anything can be done to improve this independently of Apple.

The flickering on Safari etc is very annoying but this does seem to be a bug in how the Apple API is giving us the updates for this application. It has been raised with Apple to fix.

Thanks Wim.

Thanks
 

Thank you. It is not often that a support team simply says, " we know it is slower" and we are working on it. Applause for that. I will await patiently a "fix". Interestingly, the frame rate of things like video playback etc. is not slower. It is mostly mouse and window movements. Does this make any sense?

Can you please mention the bug number and I'll reinforce it with a BR of my own.

I concur. Using 2.1 with Mavericks Gold Master and it is nearly unusable. The mouse movement is horrible. I usually run my windows VM (vmware fusion) on my second screen (via the usb adapter) and the mouse movement is a little better when in the VM. On ML it was the opposite, the movement was a little sluggish in the VM compared to OS X. Obviously 3d acceleration is turned off in the VM.

Unusable on 10.9 GM, you must suggest Staying on 10.8
 

I am running some test machines using 10.9 and I will not be able to upgrade to mavericks on our normal machines until this is addressed.

A little disappointing since apple have finally fixed there multiple display issues on mavericks and I cant update to use this on our multiple display systems.

I suggest that you make sure you tell you mac users know that an upgrade is not suggested until this can be addressed, as we expect 10.9 to be launched this week, and things could get nasty for customer support.

:-)

Hope you can fix soon.

or not... :-/

Bug numbers
 

I too would like the bug numbers.

No bug number, but DisplayLink confirmed in the upcoming release planned for November 5th they believe the sluggishness should be fixed here.

Well either the developers are very confident they've fixed the problem for all possible Mac platforms and installed software combinations, or I'd suggest it might be worth their while to throw it out there to those willing to try it out as a beta...

No beta, as we were finishing off the release. Now available from:

Hi Wim,

I just tried the new release and the video jittering is not fixed :-(. Even the small screen image of the DisplayLink monitor at the top of the screen when you invoke Mission Control is still completely broken. I've previously tried to make a video of all the jittering using QuickTime Player -> File -> New Screen Recording, but every time I try that the scrolling and jittering in the DisplayLink monitor turns as smooth as silk and life is wonderful. You should maybe look into why that is so and mimic what's going on because it would solve everything!

you said "jittering" is present but what about the lag? i think they said the jittering was due to some issues with OSX (which based on your experiment seems true)

wow. same for me. once i start screen recording all the jittering stops

Fixed enough for me!
 

The just released new stable version 2.1 on November 1st .. all of the speed lagginess has been fixed, especially with the mouse, and as well rendering issues I had with Mountain Lion on some window graphics being all distorted or squished for applications like Messages are all fixed too! WOOHOO! :D

I have not tried multiple menubar option, since i turned that off and didn't like it anyhow, but I hope that is fixed too!

Same for me. Start recording with Quicktime player and it becomes normal. No jittering and delay at all
