OS: Ubuntu 12.04 Beta 2
Card: Gefore 8800TS 320
Ubuntu Unity desktop lags when redrawing the desktop (initial login, after a game closes)
Games have poor performance - they go from playable to slideshows
This was on a 12.04 testing box that was upgrade from 11.10. All worked fine until the recent Nvidia driver update that went from 295.20 to 295.40.
Reinstalled Ubuntu 12.04 beta 2 and installed only the Nvidia binary driver 295.40. No other patches were applied. Performance was still regressed.

This is a testing machine so if more tests need to be run I will have no issues running those.
