Issue observed after upgrading to W11.
I've experienced similar changes after upgrading my system. The performance drop you're seeing is common when switching from older to newer hardware, especially with BIOS updates. It seems your CPU usage isn't consistently high enough to keep up with the demands of modern games. The fans not following their curves might also be related to thermal throttling or power management settings. Have you tried adjusting your BIOS settings or checking for any firmware updates? It might help to see if those changes stabilize the performance.
