I have a WinFast PX7800 GT TDH MyVIVO Extreme, when i had the old drivers 83.10 which I got from the leadtek site I had great FPS, lowest it ever went in multiplayer was 115. Now I had to upgrade to the newest drivers 169.21 that I got from Nvidia site and the FPS will drop to 30 at times which is killing me. I had to upgrade because with the old driver my game would constantly crash. I'm stuck between old drivers with great FPS but constant crashing, or use the new drivers which suck for FPS but no crashes. I just wanted to see if anyone knows of a way I can get the best of both worlds, FPS and no crash. BTW I play on all setting low low low w/ old and new drivers.
Forget the new drivers if all they do is screw up your fps. Just skip this driver release and wait for the next one and hopefully your issue will disappear. You don't ALWAYS need to update your drivers, just every couple releases. Heck, if you are happy with the performance you are getting there is virtually no reason to update your drivers every release cycle.
exact same problem here, i run 2 6800GS's in SLi and after new drivers the control panel is buggy and unresponsive and my fps have dropped by a few frames. doesnt sound that bad but i dont exactly get good fps!
on a side note, anyone know how to get SLi working. even when the "SLi meter" is showing full load i get no increase!
