If you are still facing issues, you can try out a fix that was discovered by the community:
Go to Documents
Navigate to Call of Duty > players
Right-click on options.3.3cod22.cst
Open the file with Notepad
Locate the “RenderWorkerCount” setting
You should change the value to half of your CPU threads (We will explain this in detail below)
Save the file
When editing the file in Notepad, you want to set the RenderWorkerCount to half the number of CPU threads you have. For example, if you have a Ryzen 5600X CPU with six cores and 12 threads, you want to set the RenderWorkerCount to 6.
If you don’t know how to find the number of threads your CPU has, simply head to the Task Manager, click on performance and check the CPU tab. It will display the name of your CPU and you can Google the number of threads you have.
Once you edit the file, you should no longer face the micro stutters and performance issues in Modern Warfare 2. If the issues persist and you meet the system requirements of the game, there is not much you can do. Infinity Ward is working on the performance issues that players have been experiencing lately and you need to wait for a fix.
