For about a month I haven't been able to play BF3 with my GTX 670 (windforce) after a while the game just minimises itself and I can't go back in. Now the time taken for this to happen is proportional to the graphics settings, on medium it can last for about 30 mins but on ultra it usually crashed in 5 mins. Furthermore, recently before each crash I get artefacts sort of bit pixels of primary colours then it goes back to normal and then crashes in a couple of seconds. Also I noticed the other day that I was getting these while watching stuff on youtube as well, so I turned off hardware acceleration and that is ok.
Concerning the BF3 issue, I've tried every driver, underclocked the GPU, increased virtual adress space and nothing has had a lasting effect.
So is my card faulty?
Rest of my PC specs
i5 750 @ 2.81ghz (Was at 3.8 but i downclocked it to rule out the CPU as being why BF3 was crashing)
32 bit Windows 7
Asus Xonar DG
Corsair 650W PSU
Well I just managed to play a few games on ultra with no crashes how weird. In the first match though I did get some weird artifacting but I didn't manage to record it properly. I'll keep trying and post some footage when I have some good video.
