sharkeeper, thanks for posting your ENTIRE REGISTRY!!!
I'll agree. 5.32 are far more stable. I have a BX board, and 6.18 don't agree with it.
6.18 are beta drivers, regardless of what nvidia wants you to think.
I have a 19" monitor, and the GTS's 2d sucks at hi-res, so I'm stuck @ 1024x768.
I enable anisotropic filtering and turn off TC when possible.
