I know this is going to be another addition to the pile of technical spec issues, but I feel the need to post anyway. I picked up a copy of CE along with a PNY Nvidia GTX 460 1gb (self overclocked to 851/1850). This card replaced my dated 9800GT. The rest of my system specs are: AMD Athlon64 X2 (overclocked to 3ghz), 4gb ram, Windows 7 64.
I set the game settings to a myriad of settings and my frame rates still suffer. I'm averaging 15-20 FPS consistently. After trying 1680x1050 (full screen), Textures: High, Texture Filtering: High, Shadows: Standard, Ambient Occlusion: OFF, Depth of Field: ON, FSAA: 4x, I still get low frame rates. Lowering the resolution and shadows, turning off DoF did nothing to alleviate the low frame rates. Any ideas?
