How to Fix Call of Duty Modern Warfare II Low FPS and Performance Issues

Since Call of Duty Modern Warfare II (Campaign, Multiplayer, Warzone 2.0, DMZ) is a game with graphical innovations that elevate the franchise to new heights, loading up every texture detail, especially at High/Ultra settings, will put a lot of strain on your GPU and CPU. For a better experience in COD MW2 on PC, you will need to tinker with some tweaks to increase your FPS and fix stuttering, fps drop, lag spikes, and freezing.

How to Fix Call of Duty Modern Warfare II Low FPS and Performance Issues

To resolve performance issues in Call of Duty Modern Warfare 2 on your PC, make sure to follow all methods below in this guide.

1) Best COD MW2 Graphics Settings for Performance

If you have a Low-End PC, the graphics settings under the "Minimum System" column are for you. If you have a Mid-Range or High-End rig and want to optimize Call of Duty Modern Warfare II for the best performance possible and at the same time wanna good-quality graphics, then the "Performance" settings will be perfect for you.

NVIDIA users with DLSS-supported graphics cards can turn on NVIDIA DLSS and set it to Quality, Balanced, or Performance to increase FPS in the game.

AMD users can enable the AMD FSR feature to increase performance in CoD MW2, which will noticeably lower the graphics quality. You can try it. Who knows, maybe that setting won't bother you.

NVIDIA Reflex Low Latency optimizes system latency which increases PC responsiveness. So you can turn it on.

Note that if you have a powerful rig, maybe increasing graphics settings can improve performance in Call of Duty Modern Warfare II. Because playing the game at low settings may cause a CPU bottleneck issue on your PC.

Additionally, in the View menu, if the Field of View is set to a different value from the default may cause performance problems.

2) Graphics Drivers

For the best game performance, ensure your video card drivers are up to date. Here are the official driver links:




Note: For a clean GPU driver install, I recommend uninstalling your current driver via DDU. You can check my DDU guide.

To determine which GPU you have:

  • Press Windows + R keys
  • Type dxdiag into the Run window.
  • Press Enter key.
  • Go to the Display tab.
  • Information about your graphics card (Name & Chip Type) is under the Device section.

3) NVIDIA Control Panel Settings

In NVIDIA Control Panel, there are a few settings you can alter to squeeze some more frame rates out of the game.

  • Right-click on a blank area on your desktop.
  • Click NVIDIA Control Panel
  • Navigate to 3D Settings > Manage 3D Settings > Program Settings
  • Hit Add button
  • Select Call of Duty Modern Warfare II from the list and click Add Selected Program button.
  • Then set the Power management mode to Prefer maximum performance
  • Set Texture filtering - Quality to High performance
  • Set "Texture filtering - Anisotropic sample optimization" and "Texture filtering - Trilinear optimization" to On
  • Laptop users should also set the "Preferred graphics processor for this program" to High-Performance NVIDIA Processor.
  • Click Apply button.

Also, if you have insane stutters in the game, removing NVIDIA cache files may fix your issue. Go to C:\Users\%UserName%\AppData\Local\NVIDIA, then delete the inside of DXCache and GLCache folders inside.

4) AMD Control Panel Settings

In AMD Control Panel Settings, you can change Texture Filtering Quality to Performance.

Also, resetting the shader cache and performing a factory reset in the control panel will fix massive stuttering and increase performance in COD MW2 and Warzone 2.0 (Battle Royale & DMZ modes).

  • Right-click on any free space on your desktop.
  • Click AMD Radeon Software (or AMD Software: Adrenalin Edition)
  • Hit the gear icon and go to the System tab.
  • Click Perform Reset next to Factory Reset
  • Click the "Proceed" button to perform the reset.
  • Select the "Quick Setup" or "Skip This"
  • When finished, go to the "Graphics" menu next to the System.
  • Scroll down and expand the Advanced
  • Select Perform Reset next to the "Reset Shader Cache" option.
  • Then hit OK.
  • After that, go to the Gaming menu in the top bar.
  • Select Call of Duty Modern Warfare II to customize the settings
  • Set Texture Filtering Quality to Performance

5) Windows Graphics Settings

To force Call of Duty Modern Warfare 2 to use your primary dedicated graphics card with high performance, follow the steps below:

  • Use the Windows search box and type graphics settings
  • Open Graphics Settings
  • Click on the Browse button.

8) Fullscreen Optimizations & High DPI Scaling

The "Fullscreen Optimizations" setting improves performance in some games. In other games, it demolishes performance and causes micro stuttering if you disable the fullscreen optimizations. I think you should disable the Fullscreen Optimizations and try playing Call of Duty: Modern Warfare II. If you are not satisfied, you can re-enable it. You should also override high DPI scaling behavior.

  • Go to the install folder of Call of Duty: Modern Warfare II.
    Steam: Library > Right-click Call of Duty: Modern Warfare II > Manage > Browse local files
    Battle.net: Games > select Call of Duty: Modern Warfare II > Options > Show in Explorer
  • Right-click on cod.exe
  • Select Properties
  • Go to the Compatibility tab.
  • Check the Disable fullscreen optimizations
Disable fullscreen optimizations
  • Hit the button "Change high DPI settings"
  • Tick the "Override high DPI scaling behavior" under the High DPI scaling override section.
  • Select Application from the drop-down list.
  • Click on the OK button.
  • Then hit Apply and OK buttons.

9) Close Unneeded Programs

Close any unneeded applications while playing COD MW2, as they can adversely impact the performance. These programs include web browsers, Spotify, background programs running in your system tray, etc.

You can use your task manager to stop running programs in the background. Also, if you are not using Discord while playing the game, you should exit Discord.

10) Disable Overlays

To avoid stuttering/hitching problems in the game, you should disable overlays. The Steam overlay, Nvidia GeForce In-Game Overlay, and Discord overlay have their fair share of performance problems. So you should disable them if you want faster and more stable frame rates in Call of Duty: Modern Warfare II.

Disabling Steam Overlay:

  • Close the game.
  • Launch Steam.
  • Open the Library page
  • Right-click on Call of Duty: Modern Warfare II
