Waking from Sleep Makes Some Games Perform Sluggishly

Bug Description

Upon waking my computer from sleeping, certain games will perform less responsively than before putting the computer to sleep. To be more descriptive, the games' visuals will appear to lag slightly (milliseconds) behind my input from the keyboard and mouse.

This occurs most pronouncedly with the game Awesomenauts, while slightly improving in certain parts of the level (perhaps less CPU-intensive areas). The problem occurs, albeit less pronouncedly, with other games such as Counter-Strike: Source and Left 4 Dead 2 (if not all of Valve's Source games), Beat Hazard, and perhaps other games in my Steam library I have yet to try.

Restarting the computer rectifies the problem, and renders the games snappy and responsive once again.

It is unclear whether the games themselves become less responsive (CPU-wise), or whether it is the result of another link in the chain (input, GPU, RAM, HDD).

Thank you for taking the time to report this bug and helping to make Ubuntu better. We need some more information from you before we can start working on this bug.

Please run the following command which will attach necessary information:

apport-collect BUGNUMBER
if you are using Karmic Koala (9.10) or newer, or

apport-collect -p linux-image-`uname -r` BUGNUMBER
if you are using Hardy Heron (8.04)

Bear in mind that you may need to install the python-launchpadlib package from the universe repository with 'sudo apt-get install python-launchpadlib'. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report.

If you are using an older release or cannot use apport please at least add the following information (pay attention to lspci's additional options):
First run the following commands:
1) uname -a > uname-a.log
2) dmesg > dmesg.log
3) sudo lspci -vvnn > lspci-vvnn.log
4) cat /proc/version_signature > version.log
then attach the files separately to the bug report (not pasted into comments or tar/zip-ed).

For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies. Thanks in advance!
