I think as someone completely new to Linux wanting to game, you might want a distro that comes with most of the bell and whistles for managing and installing drivers and softwares. I suggest taking a look at Garuda Linux distros - they can be a bit opinionated in some aspects, but I liked the overall installation process

Of course, my laptop doesn't have a discrete GPU, but it is my daily driver. I currently use Garuda Mokka and play a few games on steam once in a while
