Hello, I also have Win7 Ultimate and got a problem with playing this game. I bought it from Steam and wanted to play it but after starting the game I saw that the screen is flickering all the time. I guess theres a problem that the monitore has 60Hz at the moment. ( I hope you can understand, what I want to say ^^) I have a 16:9 resolution of 1368x768....but I don't think that this could be a problem.... I also tried to change to window mode with ALT+Enter but it didn't changed.
