You've been rocking it for what? Does it support the DLSS feature set now along with HDR and VRR? I mean, it sure did show me a desktop for the few days I spent trying to get a clean, working install of the proprietary driver, but I wasn't under the impression that I'd have feature parity without doing that.
VRR works as long as you're on a recent Wayland version.
HDR isn't a driver issue.
With X11, it ain't happening.
Wayland current supports HDR, however there isn't a protocol for applications to communicate with Wayland to configure themselves correctly. Some applications, like MPV, you can use an environmental variable to get HDR output (but not dynamic HDR, like HDR+ or Dolby Vision) and you can configure the parameters in the config.
Gamescope, the compositor that Valve uses for the Steamdeck, supports HDR for gaming. It works well for some games and completely fails for others.
Luckily, there's a Wayland color management/HDR protocol that is staging for an upcoming Wayland update so you won't need to depend on Gamescope to use HDR.
DLSS works in the games I've seen.
All of that in fully open source drivers? You sure about that? Is it per card?
Ultimately this is pretty much my point, you wrote a whole paragraph about this and I'm still not sure how accurate it is, which cards have which features supported or whether we're even talking about the same thing.
Considering the competition's implementation is "install this one piece of software day one, never think about it again", that is some ways away from a "pretty smooth experience", even without accounting for the parts that are buggy.
For the record, I'm aware of the state of affairs for Nvidia support overall (unfortunately, wish I didn't have to be). I'm gonna say you're wrong about HDR being a driver issue, though, seeing how it was outright disabled for what, three months? due to a showstopping driver bug. It seems to be back to working now, though.
In any case none of this is normie-friendly and an absolute dealbreaker for anybody on modern Nvidia hardware.
How are you going about getting the driver?
The proprietary driver? I went distro hopping, ended up trying four or five different ones. Some had the proprietary driver baked in, there were a couple of different processes for the installation for the others. The GPU wasn't the only hardware compatibility issue I was juggling, so by the time I also had audio going and the right DE setup to support my display features I ended up manually installing them in Manjaro by just finding a guide and blindly following whatever they told me to do.
