I have noticed a strange issue when playing Fortnite on different Operating Systems with the same hardware.
With Windows 10 installed, my CPU load is 100%, the gameplay is sluggish and suffers from input lag. But if I play on Windows 8.1, I lose input delay and in general the game becomes much more stable, only reaching 100% CPU utilization occasionally.
I noticed that Windows 8.1 displays 4.36 GHz in the task manager instead of 4.4 GHz, and Windows 10 displays 4.39 GHz. I believe that Windows 8.1 reserved a part of the frequency, and because of this, the processor does not overload and I can get better responsiveness.
How can I repeat the same thing in Windows 10? I tried the instructions on the following site: How to Change Maximum Processor Frequency in Windows 10, but it only allows regulation below 3.3 GHz, and also if I set the max processor state to 99%, it resets frequencies to 3.3 GHz.
