Everything worked the first time except… Steam! Unable to launch it, black window which restarted in a loop.
What package exactly did you install and from which source?
the keyboard preset is in Qwerty even though I have an azerty keyboard
If you set the layout correctly during installation of the system / in your system settings then that's not really Linux fault.
I was able to notice a bug in a rather disturbing shadow/light and in the drops of water on a windshield which appeared and disappeared in a strange way.
Very well explained.
So here I am, I hate Windows, but it runs my games better than Linux and I’m really lost. I’ve just discovered Nobara, I would have loved to try it but I’m tired of starting the first 3 hours of cyberpunk again and I’m convinced that I’ll have some graphical bugs with it.
Why restart? Back up your home folder to a different drive, install the OS and copypasta the home folder back into the new system. This is literally easier than under Windows because everything non system related is in the home folder. Games, save & config files, everything.
