graphics performance drop after system sleep

patrickdempsey · 10-13-2011, 05:13 PM

This problem makes the macbook almost unusable. It is so jerky that it makes it hard to browse the web or read documents. I purchased this to increase my productivity at work, and now it has the opposite impact. Slows me down and makes me feel like I am on an old 486 computer. Since it doesn't appear that anyone is even aware of a method to solve this problem, must less near a solution, I think I will just have to return my unit.

Hope the fix this someday as it would be a great product!

Give OS X 10.7.2 a spin before you send that adapter back. As mentioned by cshbell in this thread, the recent update from Apple has resolved my DisplayLink performance problems almost entirely.

...emphasis on the almost. I just saw the performance degradation manifest again after a display detection problem forced me to run a manual detect. A reboot cleared it up and a sleep/wake cycle is not immediately triggering the problem again, but the problem appears to remain in some cases.

I don't know if it's related yet, but my Air is having trouble staying awake in clamshell mode all of the sudden. It returns to sleep after a few seconds of inactivity.

If I can determine a reliable trigger for the DisplayLink performance problems, I'll mention it here.

Does it appear to matter what brand of DisplayLink based device is being used? I wonder if swapping to a different brand of DisplayLink would work better...

I can confirm that the 10.7.2 update has fixed this for me also

We have been able to replicate the issue in our labs. The issue seems to affect 2011 models with an Intel gfx card. The 10.7.2 update fixed the issue. Let me know if you still see the issue after the update. Thanks

I'm still seeing the laggy performance, but it doesn't show up as consistently as before. Because of this, I cannot say specifically that it is still DisplayLink related - I've removed the driver and will see if the issue returns.

I try not to shut down or reboot my new MBA 2011 very often, so sleeping and resuming is fairly frequent with me. I also sleep with multiple monitors plugged in (1 mini display port, 1 displaylink, along with the laptop screen) and frequently resume without being plugged into any external monitors - or sometimes a single (different) monitor via mini display port. That might be a part of it, I am unsure.

Thanks!
