I am playing with AI and the fps is fine(never looked exactly what, but it has no slow down at all). For freezing, it will just stop completely with no warning at all and i will have to restart the comp, and no i didn't alt tab or have any other programs. ps. same thing happens with company of heroes demo.
edit Sorry didn't see that i had already posted, thought it didn't work because its on the next page.
Just grabbed my official key, time to have some fun :D @sgman; sounds like it might be a driver error; try updating your video card and sound drivers; while you are at that a windows update might be good (If you never updated any of those yourself)
Are there any drivers that i should be using other then the official radeon ones? and i am not sure what you mean by the windows updates...usually it just automatically does it. I also would like to know if there is a way to see what beta version you have.
