Fix #5: Check for new graphics drivers.

Fix #6: Disable other apps and overlays.

In order to get the most out of your Modern Warfare 2 multiplayer experience, it is highly advised that you close any unnecessary background apps. 

It is known that several of them might cause conflicts with video games. This is especially true for applications that provide overlays while the game is being played. This covers overlays for Discord, Steam, and even NVIDIA Control panel for some.

Keep in mind that these mentioned apps are working normally for most people in general. However, if you’re running any of them and you happen to experience FPS drop in the game, it’s worth checking if closing these apps will help.

There is one more thing you need to check: make sure that there are no other programs running in the background while you are playing the game. 

You may check to see whether other apps than Modern Warfare II are utilizing CPU, Memory, and GPU resources by bringing up the Task Manager software (CTRL+SHIFT+ESC) and looking at the list of processes. 

If you do not need any of these apps, you should close them down immediately.

Fix #7: Repair game files.

If nothing has changed and the FPS drop continues to make the game unplayable for you, checking for damaged game files may be to blame.

The exact steps to check for damaged game files depends on which game launcher you’re using.

You can try to check if using lower graphics settings can fix the FPS drops. To make this simple, try using the game’s presets to change the graphics settings quickly. For example, if you’re currently using the Ultra or Extreme graphics presets, try to see if lowering the Balanced or even Basic or Minimum presets.

You can also pick certain settings to change such as the Custom Frame-Rate Limit, Shader Quality, Dynamic Resolution, Shadow Map Resolution, World Motion Blur, Weapon Motion Blur, etc. Try disabling these settings and see if that will fix the Frame drops issue.

Fix #9: Use lower monitor resolution.

Another way to scaledown the graphics settings in your system is to lower down the resolution of the game, assuming that your monitor is capable of multiple resolution options.

So, for instance, if you’re currently running the game in 4K (3840×2160), try lowering that to 2K or even the more common 1080p resolution.

Fix #10: Enable High Performance Mode in Power Options.

As a general rule, this preference is set to High Performance. If you let Windows decide, though, the power plan may be switched to power save mode.

Disabling the game mode has also been shown to be an effective fix for the crashing issue. Windows’ Gaming settings have a toggle that may be used for this purpose.

  1. Press the Windows key + I to open the Windows Settings app.
  2. Go to Gaming.
  3. Select Game Mode.
  4. Turn off the toggle for Game Mode.
