Oooh, butthurt much. I've been gaming on Linux since 2006 with both Nvidia and AMD cards, and right now, the biggest hurdle I had right after rebuilding my rig was, format and install the new system boot, install the very latest developer build for the Mesa drivers (just because, and a 60 Mb download that contains the very latest fixes for the very latest games is good), install Steam (3 clicks, login), install Doom Eternal and play it, I do mean the BIGGEST problem I had with that process was setting up a Bethesda account...
Said game just ran beautifully @1440p Ultra Nightmare on a reference RX480 8Gb.
Doing the same for Nvidia required me to enable proprietary drivers, download a compiler and a linker along with the kernel's symbols, determine which driver version was best for my card (because it's not the very latest model, see), wait for the 500 Mb download to finish, wait for the compilation to end, reboot, redefine my monitor's setup in Nvidia's proprietary tool and then hope it would work (which it doesn't always).
