Max performance does not change parking cores settings. There is a need to change it in the register or via the command line. As I said, changing the minimal amount of cores to be unparked to 100 solved the issue but I don't think that I should be this way for all 12gen users to do something with powershell and use different tools (process lasso also helped and it actually lead me to understand the issue. I saw there on graph how much cores are parked currently and it creates special power plan when all of them are unparked). I don't want to use such kind of tools so I found how to solve this with command line.Did you play with settings within the windows energy settings? Change to maximum performance if not on that already for instance.
Have seen some threads about a tool called "Throttlestop", can google that one and try it out if what you read might help you.
Since on windows 10 might that also stay a thing, windows 11 is more optimized for Intel 12 gen (and newer).
The problem that I have now Is understanding why i have this issue at all? I don't think that every 12gen user should do this and that everyone have this kind of issues.
I have widescreen so i don't want to use win11 where i can not drag task panel to the side so a lot of my workspace is taken with no reason
