How to fix and reasons behind the PC stuttering and lagging issue in Modern Warfare 3 beta

If you are looking to resolve the stuttering/lagging issue in the Modern Warfare 3 beta on your PC, try the following methods.

1) Update your graphics drivers

Updating your GPU drivers is one of the best ways to deal with graphics-related performance issues in the MW3 beta. You can do this by downloading the AMD or Nvidia desktop app (depending on your card) and automatically searching for and downloading the latest version.

2) Reduce texture settings

Playing the beta on the highest graphics seems to be causing the stuttering/lagging issue for certain players. While your system may be able to handle Medium to Ultra textures, you might want to tone it down a few notches just to see if it improves performance.

Reducing the graphics is more than likely to boost your frames in Modern Warfare 3, so do try it to see if it helps with lagging and stuttering.
