Public bug reported:
I'm not sure who to report this to. I've already tried reporting it to
Nvidia, but haven't heard any response. It could be a general Linux
issue. Or maybe it's something particular to my hardware setup. Anyway,
I'll voice it here since it strikes me as the next step.
All of my Steam games run at great frame rates normally. However, upon
waking my PC from a suspend, many of them perform sluggishly until my
next reboot. It's like their frame rate gets cut in half. They're still
playable, but not very enjoyably so. Some of these games (played through
Steam) include Awesomenauts, Left 4 Dead 2, Dota 2, Counter-Strike:
Source, Half-Life 2, Portal, Portal 2 and Team Fortress 2.
However, some games continue to work just fine after a suspend. For
example, Killing Floor. It uses the Unreal 3 engine, and perhaps it is
optimized better for Linux. Also Nexuiz and Xonotic continue to work
well after a wake from suspend.
Note that while the aforementioned games run sluggishly, the Ubuntu
desktop still performs as snappy and responsive as before. It seems
unaffected by the problem. The issue is only noticeable in games.
I hope this will be addressed in future Ubuntu versions, as I aim on
continuing to game on this OS.
If this has already been addressed in newer versions of Ubuntu, please
excuse this.
Thank you.
