Thanks for the suggestion, but since Ive had other "issues" with win11, Ive switched back to a custom win10 build from fbconan and everything works excellently.
I came to the conclusion after testing dozens of different custom win11 versions, that even the basic, unmodded win10 is way snappier and faster than the ultra lite versions of win11.
Even with things like pressing the windows key and the delay it has until it brings up the start menu, the Task Manager or pressing the right mouse button in windows- the delay until it brings up the context menu, it is much higher than on win10 and it has nothing to do with my hardware or the drivers, because the amd drivers are exactly the same for both win10 and win11 and the hardware is rather potent (amd 5600g). The hardware is hella fast, at least on win10.
Another thing Ive noticed in win11 is that the UI and all icons look slightly blurrier than on win10. It is as if there is some sort of "smoothing" or smth like that, it looks as if there was a slight dust layer on the screen. Ive disable "smooth edges of screen fonts" and disabled "ClearType" on both win10 and win11, so it has nothing to do with settings. Win11 UI incl. icons etc. just looks ever so slightly blurrier than win10. I assume it has to do with how the elements are rendered in win11 with rounded corners, which require some form of antialiasing/downsampling etc. which then leads to a blurrier UI appearance.
I will give win11 the benefit of looking fancier and more modern, which it does, but it has several other downsides like being significantly less snappy than win10 and then the blurrier UI are dealbreakers for me. From now on I will stick to win10 custom builds only, after testing many different OSes incl. different linux distributions, the win10 is by far snappier and faster than any other os out there. Even older windows versions like custom win8.1 or win7 dont come close to win10.
