FWIW I am using beta Nvidia driver set 195.22 with 6150SE on board GPU.
seems to work very well 
Sound’s like some nice change’s in them as well tbh.
Have to let us know how they work out and any quirk’s you may find. Wont be testing them quite yet, I have enough problems with some of my game’s at the mo to go installing a new gfx driver aswell 
No probs at all so far… I don’t how to test and give any proper figures, but it all seems fine. Are there any test progs/benchmarks in linux?
Not that I know of, i normally test by game’s on how much i feel the driver’s improve (you normally can see a little FPS gain or loss, texture ripping or blending being wrong).
If you don’t really game though the driver’s will probably be fine and never really pushed, the change’s from what I’ve read mainly expand a little on OpenGL/Mesa 3d support. Plus better handling of the 30bit X display’s. Oh and 3d glasses support
