Game runs fine for around 45mins then my FPS drops to 2, stuttering and textures don't load properly. Happens in singleplayer, mulitplayer and in the editor. Also occurs with and without mods and changing video settings makes no difference.
Temps for CPU and GPU are both fine. FPS doesn't degrade, it just suddenly drops then crashes. I'm thinking maybe a memory leak or virtual memory issue? {F22803}
