For gaming, most distros handle it fairly well! I’ve gamed on Ubuntu and Fedora 42 (my current distro) the most. Steam’s Proton Compatibility Layer helps so much in this case, making Linux Gaming less of a struggle. Pop_OS is based on an older Ubuntu base 22.04 with software several versions behind what’s currently available. The NVIDIA drivers are at least current.

I’d not recommend that for a gaming OS until they update the Ubuntu base, when COSMIC DE is done this will likely happen. Bazzite or Nobara are solid recommendations as well, if a specific gaming distribution is desired.
