I've had no trouble with my GPU before today. It's never gotten too hot and has always provided great graphics and good fps on pretty much anything I play. But for some reason when I try playing Minecraft today it automatically underclocks itself and the game fps lags. It doesn't do this with other games and the clock stays put when every I play other games. But whenever I start Minecraft up it stops working almost. It still is working but it's using almost none of the card and its clock drops to below half of stock. Anyone know what might be the problem?
