Good experience.
Installed CachyOS on my T440 and tried Luanti and I got 60 FPS without zero lag but full smoothness.
On Ubuntu and others I was getting 40 FPS and lower. Battery life got longer dramatically but I just installed this yesterday night so I need time.
Boot time is longer than Ubuntu ironically. Ubuntu is the only distro that boots up very fast.
And, compared to EndeavourOS; wish they cared about being close to vanilla Arch and small details... Like EndeavourOS's KDE works smooth and fits my screen. Installer etc. everything is simple and minimal.
My YouTube video issues are still existing and this was happening on vanilla Arch too doesn't matter what I do... Maybe I should use chromium? But OTOH stremio is also blurry a little bit not extreme.
