I'm playing Rome Total War and it get's very slow when I recruit a lot of units and espacially if I zoom into them to see how they are fighting. It's fine if theres only fewer units so I don't think it's the video card but I think its the ghz because mine is only 1.1. How can I speed up my computer to play the game faster? Are there any programs that speed up computers? Any software I can download or purchase? Anything I can do to my computer?
