I read the whole thing, our system is fucked.

I'm using KDE and when I download a flatpak it automatically creates a .desktop file. I think gnome does this too if I'm not mistaken. I do have to restart or relogin for it to put the file there but that's not that bad IMO.

Not sure if this will fix your problem but try Wayland and see if you have the issue. I don't know why a lot of my problems with games were fixed and it might help you.

It's insane how I just had this problem today. Had to tear out my network card in my Asus VivoBook 16. The drivers aren't out for the MediaTek network card so I had to change it to an Intel one that I previously used.

Well this isn't a DE thing but I would like good ray tracing and the new frame gen support for my AMD GPU.

Librewolf is able to do that by turning sync on in the librewolf settings.

I am reading the wiki, but it is mostly discussing PulseAudio and not providing much information about PipeWire. I am unsure whether they share similar file locations or configuration processes, and I do not want to arbitrarily paste PulseAudio commands without knowing their potential effects.

My headphones are not Bluetooth, and I have already disabled the EQ. Disabling the EQ has not fixed my problem; it has only made the sound slightly more bearable.

Good to know. 👍

I already have the game installer, I just wanted to use the install script from the app.

For some reason i still have bad mouse lag on x11 but it could be nvidia or my driver for all i know.

I would say Debian, its stable and customizable.
