That might just be your GPU. If you’ve tried different distros and had issues on others then you’re probably right but different Nvidia GPUs can have varying success. I use two machines with different Nvidia GPUs (both running endeavourOS) and one needs drivers from flatpak to play games at more than ~20fps.
Try Fedora KDE spin next time. It handles my Nvidia GPU without any trouble.
