So, the game was running fine 2 weeks ago. I installed the mumble client and odd things started happening in game. I used the Sourceforge download. Even after uninstalling Mumble it still happens.
After this was shot, I played with the AA settings in game and saw some improvement, but some artifacts were still there. The is a new Mac Mini in Bootcamp, Win 8.1, Intel Iris 5100 graphics, 8 GB ram. Any thoughts?
