My roommate and I are playing on teams, and he is crashing each time he uses a hero for the 2nd time. We play one game, and we are fine. We then exit out, and get back in (since we can't seem to join each other if we don't, but that looks like a known bug). After the game starts, he will crash after about 5 seconds.
He is in compatibility mode.
He's tried playing as different races.
I've tried changing what race I play as.
He is able to play on single player just fine.
