In games such as BF3, on outdoor maps my fps goes way down compared to maps indoors, im talking from 160+fps to 70-80. However in games such as Metro 2033 and Hitman Absolution, the FPS is stable. My specs are 2xEVGA GTX 670 FTW@Stock speeds(314.07 Drivers), i7 3770K @4.4Ghz(never goes over 45C), Corsair Vengeance RAM @1360 Mhz, 120GB SSD OCZ, Asus P8z77-V Pro and an HX750 Watt PSU by Corsair. I think it may be my ram but I'm not 100% sure because every time I clock it at 1600mhz (base clock for it) my PC crashes, even with a different motherboard inside. Also my GPU usage in metro and hitman is always 90-100%, however in BF3(just outdoor maps/parts) the usage goes down to 60-70% Here is a link to my RAM: http://www.corsair.com/en/vengeance-16gb-dual-channel-ddr3-memory-kit-cmz16gx3m4a1600c9.html Any help would be great, thanks.
