Okay the game didnt seem to crash this time, but the framerate still drops. This time it drops when im not doing anything, just waiting for units to be built. Then after a few minutes it shot back to normal, then again a few minutes later it went to down. When it goes down it goes down to ~1 FPS. The previous post i was looking at the World/Update FPS not the Render one. My CPU usage was only between 25 - 30% so that shouldnt affect the game. I cant see why its dropping.
