So I’ve been playing a normal match, just me and 3 computers, free for all. On a map created by Blizzard (The Glaive, I think?) Anyways, the game was running mostly fine for the first 40 minutes or so. There were some bad framerate issues, but nothing too serious at first. Then suddenly out of nowhere my screen goes black. I can still hear the game and it responds to f10 but I can’t see, not a thing. Alt Tab does nothing. Ctrl+Alt+Delete does nothing. I have to hard press and turn off my computer every time it does this. It has happened 3 times now. This doesn’t ever happen on custom maps that I create. Why is this happening? I just want to play a normal, Melee Match against some computers. Instead I get this problem over and over.
