I just tried the driver sweeper, but it did not do anything. As for the temps, at full settings on many games, 40" HDTV and 22" LCD, I would get about 45C max. Now with this issue, I idle at 36-40C. But it is wierd that this only happened after updating drivers from october to the current ones. Just progressivly getting worse. Minecraft is now spikecraft.
Also, now the images are "tareing?" on my desktop when moving things around or selecting selecting things on the start menu
