You have been subscribed to a public bug:
While the information was being collected to report this bug I got this
message.:
Your system is providing 3D via software rendering rather than hardware
rendering. This is a compatibility mode which should display 3D
graphics properly but the performance may be very poor. If the problem
you're reporting is related to graphics performance, your real question
may be why X didn't use hardware acceleration for your system.
The problem might be related to the above message that appeared. Just
after upgrading to 12.04 precise from 11.10, all fullscreen games lag
badly. I am using xserver-xorg-video-openchrome drivers.
Here are the contents of my xorg.conf:
