I’ve been using NVIDIA graphics cards for long time (GTX970 and GTX1070 mainly), and I’ve faced lots of issues, the main ones being the permanent sluggishness and lag of KDE, and less perceptible but present also using XFCE.
I’ve installed endeavouros on many computers, including really low power ones using intel Celeron J1900 with 2GB of RAM, and there was no problem at all, KDE was normally responsive.
At home, using a really powerful computer (Ryzen 5950X + GTX3080Ti…) on a 144Hz monitor, EndeavourOS + KDE works really really well, with no delay, lag or sluggishness at all.
For me it’s hard to accept that the same installation works fine on low end computer, on really high end computer, but it works really bad on my midrange computer.
So, I switched from NVIDIA 1070 to AMD RX550… and then WOW ! No stutter, no lag, no sluggishness AT ALL ! No need for driver, no need to enable FullCompositionPipeline, no need to edit any conf file, to modify kernel parameters. X11, Wayland, Electron apps under Wayland… everything works just fine.
I used to have such bad experience with ATI graphics cards under Linux long time ago, that I spent years not even considering using one again, my mind is now changed for long !
