Download from releases.

Run the file as administrator.

Select the process that contains the executable in question.

Select priority.

Click Set.

Relaunch application in question to see the new cpu priority.

It adds a registry key for the selected executable and a sub key for PerfOptions, and another value for CpuPriorityClass

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options<Process>\PerfOptions

CpuPriorityClass

Certain applications benefit from having higher CPU Priority. This sets the application to launch with that higher priority every time using the registry, no more going into task manager to change it.

Using higher piroirites can move applications off of efficeincy cores. I have heard anecdotal evidence that Easy anti-cheat games preform better when the cpu profile is set higher but they dissallow these changes through task manager, hence the need for a registry edit.

Junk code, not really a developer.

Thanks go out to mirko8054 on reddit for their instructions on doing this for a video game. https://www.reddit.com/r/starcitizen/comments/qw6ff7/set_cpu_priority_after_easy_anti_cheat_release/
