on my GTS250 i don't see any improvements (when KWin is active anyway) in Unigine Heaven 2.0 ~701pts @ 1920x1200,noAA,16xAF,all active
(stupid 1minute edit timeout rule)
and another thing worth mentioning: the OpenGL renderer in Unigine Heaven 2.0 does not run tests 7, 10 and 12 ( you only get a black screen ) while the DX9, DX10, DX11 renderers will run them so any cross platform/renderer comparisons are rather broken
The new driver isn't bad. I am trying it in windows 7 right now and playing starcraft 2 beta with it. So far the glitches I'm experiencing are most likely game related anyway... I had some problems with on board gpu causing issues too, but fix was to disable on-board gfx.
BOINC becomes extremely unstable for me with this driver. I'm crunching for gpugrid with 2 470s. Frequent lock-ups, powermizer wont leave desktop mode on 2nd gpu, boinc process requiring 'kill -9' to restore functionality to desktop (if I'm lucky enough to not lock up)
Worst thing is I can't find anyone else experiencing this.
