Call of Duty: Modern Warfare 2 (MW2) is a refreshed and exciting game from the CoD series that gained a considerable player base shortly after its release. It is also a hardware-demanding game requiring a good internet connection for multiplayer. However, even with a powerful PC, the game may stutter even with low graphics details. Aware of this problem, we created a guide to help you solve MW2 stuttering on your PC.

Why does MW2 stutter on my PC?

The problem of MW2 stuttering on your PC can be due to several reasons: low-end PC, outdated graphics drivers, not updated system, full-screen optimization turned on, issues with overlay app, corrupted game files, in-game graphics settings, overclocking, insufficient RAM.

How do I fix stuttering in MW2?

First, you should check the recommended system requirements of MW2 to ensure the game has no compatibility issues with your PC. If you find that your PC does not meet the system requirements, you must go for the option to upgrade specific hardware (GPU, CPU, RAM, etc.). Let’s assume your PC is compatible with regular MW2 operation, and you still have stuttering. To successfully eliminate the problem, do the following:

  1. Update GPU drivers
  2. Update MW2
  3. Update Windows OS
  4. Run the game as an Administrator
  5. Lower in-game graphics settings
  6. Disable fullscreen optimizations

1. Update GPU drivers

Outdated graphics drivers are one of the most common causes of game problems, and updating is the first step we recommend. AMD and NVIDIA are trying to implement all corrections of observed game problems in new versions of their drivers. That’s why we strongly recommend you update the graphics drivers. Here’s how to do it:

1. Right-click on the Start Menu and choose  Device Manager from the quick access menu.

2. Double-click on Display adapters to expand it.

If there are no new updates you have checked previously, please visit the official website of AMD or NVIDIA and download the latest version.

9. Raise Spot Cache to High or Ultra

Another solution to the stuttering problem that we have seen in practice give a concrete result is to raise the “Spot Cache” setting to “High” or “Ultra” in the game’s graphics settings. Unfortunately, we don’t understand why this setting has such an impact on stuttering. Maybe it’s a bug in the game, but try it because it helped us eliminate stuttering on some PC configurations.
