I think my system (in my sig) is pretty decent, I'm used to running games at high settings without any trouble, but CoD: World at War is giving me some problems. Online multiplayer works great, but in single player my FPS drops down to as low as 11. I'm using the latest drivers and I have the game patched to the latest version. All the settings are set to default, except for the resolution which is at 1680x1050. Any idea what might be causing the trouble?
