After installing Windows 11, the processor fails to achieve its highest turbo boost speed.
I switched to Windows 11 yesterday and found it actually performs better than Windows 10. However, in games the CPU never exceeds 3.77 GHz even though the turbo can reach 4.6 GHz. In contrast, Windows 10 would consistently push the CPU up to around 4.4 GHz. I considered a BIOS update, but it didn’t help either. I’m also using high performance mode, and outside of games the CPU operates at its 4.4 GHz turbo speed without issues. My main worry is that I might be missing out on full performance potential. I haven’t adjusted settings much in XTU, but that shouldn’t be the issue. My system specs are an i5-9600K on a MSI B360M motherboard with an RTX 3050. The only related discussions I’ve seen are about laptop CPUs, not my desktop. I’m curious if tweaking BIOS settings is necessary or if Windows 11 handles clock speeds differently, so I don’t have to sacrifice performance. I prefer Windows 11 and would appreciate any advice.
Consider turning off Windows 11 VBS feature. Check the instructions on beebom.com for details. Afterward, apply ThrottleStop and capture screenshots of the main window, TPL, and FIVR. Some systems struggle with CPU settings in Windows 11, which may limit performance despite being rated fully. This isn't a hardware issue—it's a software bug causing speed drops.
I resolved the problem by reinstalling Windows 11. The issue likely stemmed from the upgrade process itself.
