MSP2551,
I'm having nearly the same problem as you with the GEForce..is the 30.82 still working for you? I tried it after reading this thread but am still having the same problem with CMBB..the game is almost unplayable unless unless I play it bare bones which isn't a lot of fun. Never had this problem with CMBO..ran like a greyhound even with all those hi-res mods..If you find a solution to this let me know and I'll do the same.
