Games were running fine on win 10 on battery. But since I clean installed win 11, the CPU usage drops to less than 20% when gaming and the game barely runs on 10-15 fps. As soon as I plug the charger while still gaming, the CPU usage jumps to 60% and above and the FPS are back to above 90.
GPU usage is above 95% which makes me believe that GPU is performing fine both on plugged-in and battery. I have verified it using MSI Afterburner stats.
I have set performance profile to battery from System, set all the performance parameters to maximum in Power Plan. Set profile in Nvidia Control Panel as well and everywhere I could find
I have updated to the Win 11 KB5007215 update released yesterday on novermber 9 2021. The issue still persists.
