Usually I can do gpu folding(GTX 570) while playing games with graphics that are not intense like Street Fighter IV, Sims 3, Dishonored, and CSS with 306.97 while still getting constant 60 fps. However, when I update the video driver, game starts to lag when trying to fold while gaming. I'm talking about fps in 5-20 range. I tried using driver cleaner programs, but still doesn't work. But reinstalling back to 306.97 solves the problem. I doubt that it's a PSU problem, my psu is OCZ 650w ZT modular. It seems that I can't go beyond 306.97 if I want to fold while gaming. It would be nice to havee the benefits of updated drivers for future games without this being a problem. My [email protected] client is 7.2.9. Can anyone help?
