FPS drops
Yesterday, my game played fine on medium settings. Constant 60 FPS.
Today (within the last hour) I entered a game and the fps had dropped to 20-25. I disabled shadows and that seems to be the only thing that makes any difference at all. It went back up to around 45, but the oddest part is that I was able to set other settings to high and it stayed above 40 as long as shadows were completely shut off.
