I had stopped playing for a while and I just started again because of the new talents.
It isn't a lag issue its a drop in FPS issue. Recently, in the last two days, the computer itself will actually just lock up or freeze. I won't be able to do anything except move the mouse. If I am lucky it will unfreeze and I can continue playing. If not I need to shut down the computer by holding the power button.
Any ideas?
