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.
