What resolutions are you guys with the same GFX runnin at, and are you running window mode? I know some comps that have issues running the game will do better if you lower the resolution. If in window mode this will kinda be a pain(imo) sense the window will be smaller. But if you do a lower res with full screen it will run better. No one likes to reduce there quality, especially when they haven't had to before. But this will undoubtedly improve frame-rate, while you wait to find answers. I wish there was a wat that you could still alt + enter to make it maximize with window mode. A lot of games these days are starting to support that.
