Hello fellow overclockers! My CPU is i9-14900K and mobo is AsRock Z690 with a memory running at 6600Mhz@30-37-37-48. I have a dual boot system so without changing ANY bios settings the TimeSpy CPU score on Windows 10 is about 10% higher ~26700 vs 24480 – see the pic. This is 100% reproducible – Windows 10 always scores in that range and for Windows 11 this is in fact my highest score as it's usually around 24200-300. The thing is that my Windows 10 is old with tons of apps installed since it's my main OS for gaming and stuff. While the Windows 11 installation is pristine and just for benchmarks. But whatever I do (including reinstalling Win11 twice with different distributions) I score much lower on Windows 11. I need help finding what might be the issue here. I read some older threads for Windows 11 fixes, but none of that seemed to make any difference. I'm not finding any similar thread so I wonder are you happy with your Windows 11 performance – 10% seems a pretty big hit, it's like your 14900K turns into a 14700K on Windows 11 (at least on TimeSpy), which is bad. Any help will be highly appreciated !
