Windows 8.1, Intel i5 3570k overclocked to 4.2ghz, 8gb ram, Nvidia 660TI.
When it loads it runs fine ignoring the fact it doesn't support 1440p, just a good number of campaign missions don't seem to load. I tried Wu, Wei, and Lu Bus campaign, Lu's was fine, other two I managed to do the first stage and after that wouldn't load at all no matter what I tried.
Thanks, that's close to mine specs, only different video card and I still haven't updated to 8.1.
I'll hit forums later to see if I can get more info about it.
