You could check out distros like mint, zorinOS, fedora, popos, and Nobara. I think all of those will come with nvidia drivers so you don’t have to set them up manually. Nobara in particular is set up for gaming out of the box, I don’t know how well it actually works personally. You could just install Ventoy on a USB stick then load up multiple Linux distros on it, then just select the one you one to try live at boot. Mint and zorin will be the most familiar.
