So I have Windows 7 RC as my OS, and when I boot up Empire Total War, it starts fine, I start a campaign, it loads, and then it freaks out, gets all twitchy, switches between the load screen and the game, colors get distorted, and it just looks really weird. I can't control any of it either. Sometimes their is the classic "there's something wrong" buzzing noise from the game. So, how can I fix this?
