Here’s my MSFS BAT files that kills all the junk and load secondary software with CPU affinity to cores 13-24 (I have 24 logical cores on 5900X). You can use it as a template, but don’t forget to change affinity to your CPU or just remove /affinity xxxxx from the commands.
Analyze your running processes and services. Try command line to kill/stop them and if you can and nothing crashes - add them to the bat file. Every little thing helps. Be careful with system processess though.
taskkil command kills the apps, sc stop command stops services.
Salt to taste.
