My quick rebuttal is that gaming is pretty close to 'there' if you pick a distro that prioritizes it. I run bazzite-DX (nvidia rtx4070) for dev and pleasure and gaming there is ON POINT. I don't play any anti-cheat games, but Cities Skylines, Doom Eternal, Cyberpunk (with full raytracing and HDR), GTA5-Remaster, etc, all run like champs. As of last month, full HDR10 mode started working in chrome and video players too, so hdr videos get those popping brights.
