Boys, I tried. But I couldn't get HDR working properly in KDE, the kernel kept randomly locking up to the point where even REISUB didn't do anything, and 95% of my GPU settings were missing from the Nvidia X Server app and I couldn't get most of them restored.
Linux users look at me like I'm insane when I ask where the RTX Video Enhancement and 3D settings are. Half the reason why I bought an RTX GPU was for the video enhancement features like SDR to HDR conversion and AI upscaling, yet these features simply don't exist in Linux. And when it comes to the 3D settings, "just change the graphics settings in-game", I've seen people say, failing to realize that the vast majority of games are missing several graphics settings that are in the 3D settings screen. I go into that menu and make tweaks before I play anything. It's a make-or-break feature for me.
I'm sorry but Linux still hasn't caught up enough with Windows yet in the gaming and HDR realm for me to commit to an OS change. But if you have an AMD GPU and don't have an HDR display, I'm sure it's a wonderful gaming experience for you. I'll check back again in another 5 years.
