Well nvidia drivers right now suck a$$, I installed the latest 163.71 whql's and they made my games run like terrible. I have the 94.24's on my system and they work 10 times better. My graphics card is the 7950gx2 and they love them. You prob need to refer back to drivers that worked well with games with no issues.
I have Stalker as well and had the latest drivers too... The game ran crappy, I literaly had to put the game in DX8 mode. Untill I went on the nv web site and asked what are the best drivers for my card.
Made a huge differance. I play all my games at max settings at 1680 x 1050. Even when I play Bio Shock and ET quack wars no issues..
BTW did you update the patch for STALKER 1.4
Just because nv releases new drivers, they don't really work, that's my opinion.. Find the best driver on nv site That's Nv recommended and whql certified. That helped me... good luck
