I beaten this game up until the second rift in Act IV(Inferno). Every time I have entered that rift on Inferno mode, while I was making my way to the next checkpoint, the game decides to freeze on me during combat. I don't know how or why this happens, but I can't get my Diablo Inferno achievement if this problem persists. Has anyone else experienced this? Playing as a L60 P4 wizard on Hard difficulty. Not sure if that has anything to do with the freeze I'm getting, but this happened every time I started up Diablo 3.
