Just installed Windows 7 with all newwest OS updates and drivers form my components. Downloaded few of my games right away from steam and all worked fine but Dishonored wasn't one of them. With windows XP i had stable FPS at 1280x1024 all maxed including the AA! The FPS never dropped below 40 which for me is excelent. Now I get barely 35 and there are drops to 20-22 when walking around. Yeah I know Win7 uses more resources but Skyrim for example runs 20, yes twenty Frames higher than XP for me at the same and even higher settings! What is going on here?! Tried different sound and video drivers nothing seems to help :/ XP is not even official OS for Dishonored and it perfoms better? That can not be true...
