This is exactly what happens to me EVERY time I play. I'll get 15-20 minutes of smooth gameplay then the screen goes black and either the computer crashes or the game lags like crazy and all animation is choppy. While Simcity is still running like this I will open MS Flight Simulator and have no issues at all. The second I switch back to Simcity, it's awful.
I'm running a brand new AMD Radeon 6750 with 8GB Ram and a 3.6 ghz dual core and am blown away that this kind of thing can happen with just ONE game.
Also happens with my other Origin game: Dead Space 3
