I have a 6800nu and for some reason I get major screen corruption in Painkiller. The loading screen(s) flicker with artifacts and the game freezes in the (also corrupted) menu if left alone. Nothing in my system is overclocked, but I do have an extra vertex shader unlocked. Every single other game I've tried so far has worked (Half Life 2 works flawlessly for hours, as does Doom 3, Far Cry, and Battlefield 2). I updated Painkiller to version 1.64 (the latest) and still, same problems. The temps dont seem abnormal, and nothing weird happening to the clock speeds and temperatures. I have the latest final drivers (77.72). What gives? Do I have a bad card or does Painkiller no longer like my sistem? It used to work like 2 weeks ago, and nothing changed between then and now.
