Hello there!
I own a HP Pavilion Gaming Laptop 16 (specs at the end) and some months ago I decided to install Windows 11 since I wanted a clean windows. The experience I had was very laggy through Windows and game performance is absurdly low. For example 20 FPS in Fortnite (low). And I did a dual boot with Windows 10 to do a benchmark. I used the Heaven Benchmark and obtain a The following with the high quality and default preset:
Windows 10 -> 113.8 FPS, 2867 scoreWindows 11 -> 84.9 FPS, 2138 scoreDiference of 28,9 FPS
Have in mind that I have updated both OS with the lastest Windows version of each one and the nvidia driver version (546.17) is the same. Also in the oficial HP support page it says it only support windows 10. And I want to know if there is something I could do to increase the performance (apart from overclocking) in Windows 11, or if I should stick to Windows 10 until end-of-life.
