You can tweak many features via console commands and the built-in settings, but this app from Steam forums user DustinEwan is much easier. Load in your configuration file and the most troublesome graphical effects can be switched off with a single mouse-click. This includes Glow, which shouldn’t be a problem for the engine but apparently is, Depth of Field, which blurs the screen past a certain distance and can be a major problem if your graphics card is only just up to running CODBLOPS, and smaller details like whether VSync is on or off. As with all tweaking, it’s best to switch one off at a time to see the full effect: we recommend going Glow, Depth of Field, Distortion, then Blur.

Hey! i tested it too! it is best to remove Glow, Depth Of View And Vsync for optimum smoothness.
