Hi chris...
This explains the process pretty well for w10 and w11...

Note that this only sets what the maximum is - the CPU 'decides' whether it needs to go into turbo mode, and by how much, taking into account thermal management.
you can't just 'force' it....unless you have a cpu that can be overclocked....
personally - setting my old pc to 'performance' can result in instability - so i just leave it in 'balanced'
I'm not even sure if performance mode actually gives me anything - i dont use my pc for gaming, so FPS on the screen is not important....
my biggest consumers of CPU are deep sky stacker and Siril - and for these apps, it seems to make no difference...
Cheers,
