Basically, with 3 Hard AI in map with me, making it 4 in skirmish, when I reached 15mins in-game, the fps starts to slow down. I do believe it is part CPU, part RAM, part GPU.
But can someone give me a rough estimation on the percentage of each factor that affect the fps in-game? I'm convinced it's just the matter of how much objects are currently in the game. When the game just started, the speed is flawless and smooth.
Like, is it highly depends on CPU and not so much on RAM and GPU? Or?
I'm using a 20" monitor with native 1600x900 for resolution of the game and standard rendering btw.
