A small script to set processor priority for Call of Duty: Modern Warfare.
Run as administrator
PS > ./CodMWThrottle.ps1 -Install -Priority AboveNormal
Priority Levels are here: https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.processpriorityclass?view=netframework-4.8
The game will start with Normal Priority and raise to High after it's done loading. It's reccomened to use AboveNormal, otherwise you could run into problems with dropped frames.
