Sorry if this is the hundredth similar topic - I just don't feel like bumping old threads. So here goes; Specs ; 2.66 GHz Intel Core 2 Duo 2 GB 1067 MHz DDR3 NVIDIA GeForce 9400 256 MB VRAM iMac 20 inch - 1680x1050 Resolution, running COD4 v1.5 In default settings, my FPS would be around 20 to 50. And in my opinion, that's pretty terrible for a pretty new iMac. In default settings, the resolution is only 1028x768 in default settings and the texture and graphics are really ugly and yet it still runs pretty choppy in the battlefield. If I change the resolution to 1680x1050 which is my max resolution, it runs very very choppy and slow with around 5 to 15 fps with no AA on, Shadows off, Texture low and most of those are either off/low. Any solutions? Thanks in advanced.
