I recently got BattleField Bad Company 2 on my PC and getting extremely poor performance. I run the game at 6050x1080 (5760x1080 bezel corrected) and I get average frame rates around 30 with frequent dips of 20 fps. I tried multiple settings such as turning off AA and AF, along with HBAO. After lowering the resolution to 1920 x 1080, lowering shadow and texture settings, and turning multiple settings to off I get an average of roughly 45 fps. I have tried both DX11 and DX9 settings, neither seem to make a significant impact on the game's performance. This performance is outstandingly bad and after viewing benchmarks of 460 SLI (which is slightly worse) I think I should be getting 2-3 times the performance. I have the most recent drivers. I'm thinking my PSU might be to blame, but I never get any crashes. What is going on here? The rest of my system is as follows.
Intel Q6600 Quad Core OC'd to 3.55GHZ
G.Skill DDR2 Ram 4gb (2x2gb) 800mhz
ASUS P5N-D 750i Motherboard
PC Power and Cooling 750w Power Supply
2 X PNY Nvidia GTX 470
3 x Alienware AW2310 Monitors
also, your cpu wouldn't handle that resolution even if your gpu runs at 100%.
