So far game runs fine for me other than some minor performance issues when looking around (with mouse + keyboard and 360 controller). My specs are a lower end pentium dual core @ 2.8 ghz, a radeon hd 4890, 4 gb ram, etc etc. Maybe it is just my hardware that's causing the slight performance drop but I doubt it, played the recent medal of honor multiplayer beta at full specs and it ran smoothly.
So just here to report that the game froze on me when I accidentally hit my windows button on my keyboard. I tried to alt-tab in and out to get it working again, used the task manager to try and force back into the program but I just had to force close it altogether. Also, I could still hear the game sound still running. Hope this helps the tech team.
