Personal report, I am done, just rolled back to windows 10.
Spent about 1 month trying to use W11 and here is a list of the major step backs I found for my usage:
Windows initialization W10 = 13 seconds / W11 40 seconds (Same clean install settings)
CSGO initialization W10 = 5 seconds / W11 25 seconds (same settings)
CSGO FPS W10 = 600~700 / W11 = 200~300 (Same settings on middle de_mirage)
CSGO random issues during gameplay or initialization (refresh rate drops / colors faded / random crashes)
I am not exaggerating, it is literally unplayable for competitive players.
Ref. Intel Core i9-10850K / RTX2070 / Crucial MX200 SSD
The worst part of W11 is this Non-Stable felling of the OS, I felt like a beta tester of features.
For about a month, every update made things even worse/slower and I am not even mentioning other issues among professional software that I use.
Went back to windows 10 and will wait until things get a little more stable.
