Bennycal the cpu you have is crap.Intel celeron is low end and it's single core,makes it even worse. Because supreme commander needs dual or quad core to play great,the reason is all the path finding,ai and projectile calculations + massive armies and buildings on the screen at once.In a 8 player game we talking eight thousand units if the settings is at thousand for each player.Don't forget all the buildings structures to,but the rest of the components will handle supreme commander.
