So I just built a gaming pc. I have: i5 3570k, HD 7950, and 16 gb of RAM. I have already played Civilization and Empire Total War on max settings with no problems. However, when I play Crysis 3, it runs beautifully for about 3 minutes before i get switched back to my desktop home screen. I can just click on the tab and jump right back into the game. It is almost like something is interrupting the game. I have Windows 7 in case that is relevant. I increased the settings a little over the preset suggested ones, but if that was the problem, wouldn't my game be sluggish instead of fluid? I have not overclocked any of my hardware. I just updated my motherboard BIOS to try to fix the problem but that did not work.
