Well if you look at the thread for it you can see builds for windows , mac and linux
It ought to be better than RC3 for a start but it neednt necessarily resolve your crashing issue.
I was thinking about other causes of the problem other than just the drivers.
Issues with particular .obj, materials, textures and UV perhaps.
Or an issue with the power supply or cards+connectors not seated properly.
You could try going back to the last cuda3.0 driver if you feel cuda3.1 is giving problems.
2.2b was developed with cuda3.0
