    The answer is a bit complicated. Linux has a long history with HDR where you would need exact software and hardware, or else no HDR… Just know that it will get easier because the ball has already started to roll in the correct direction.

    But the shortest way I can say it now,

    If you use Valve’s game mode, (which is possible to get either using steamos, bazzite, chimera OS, nobara, or you can manually set it up. You should be able to get it to work. This should work for windows games that support HDR. AFAIK there are no Linux games yet supporting HDR. It should be possible to get videos playing with HDR also, but that would be an exercise for the reader, or wait until people make it easier.

    Please correct me if I am wrong, but I currently believe the newest version, of KDE and Gnome are now HDR ready. If I am wrong you might just need the newest beta which will become stable Q2 this year.

    Playing videos, I believe the newest version of MPV just got HDR support. With more apps incoming.

    Anything that let’s a gamepad or a remote browse your videos? AFAIK not yet, but be patient, as this is all new

    The first few times sitting in or driving a tesla was cool and novel. But after you have used the fart simulator app a few times, and let your sister in law post a few pictures. It’s just a car that takes a lot of space in small parking spots.

    It is low quality, breaks often, expensive to repair, barely fits parking spots, expensive to buy, has paid for addons that have been coming soon the last 10 years

    There is a lot of other electric vehicles I’d rather have

    To be fair, (I hate Nintendo because of their crusade on open source software), but to be fair,

    ps2 had issues on some Ps1 games, the list is short though, and the last few revisions of ps2 even software emulated Ps1 (don’t know the compatibility difference with hardware backwards compatibility)

    Ps3 had issues with even more ps2 games, and only the first few revisions had hardware backwards compatibility, the ps2 emulation on ps3 without hardware compatibility is a mess

    PS5 has issues with some ps4 games, including but not limited to psvr games, and I think I saw an official in incompatibility list by sony

    Wii backwards compatibility i dont know about any issues except with games that use hardware accessories, maybe someone knows more? Later revisions dropped backward compatibility, but the hardware is still present, and homebrew will help you.

    As for switch 2 to switch 1 backwards compatibility speculation, here is a educated guess. The asterisk is referring to lobo games and some other games with accessories. Why this speculative conclusion? Because of the way the hardware inside it works.

    The arm cpu can be optionally designed to be completely backwards compatible. But is it? (more on that soon). The gpu part of the SOC, is most certainly not 100% binary compatible, because of what we already know about the architecture changes between these gpu generations. This isn’t limited to arm and nvidia gpus, ps5 also has these issues with x86 jaguar to ryzen, and Radeon generations.

    So what about your experience with pc gpus, and cpus, and ps5 to ps4 compatibility etc? Well, emulation, the instructions, that are not compatible are emulated in software, this is common place, and in practice it works quite well. The main issue comes down to timing. Some things take different amount of time to do, like an instruction can take fewer cycles. Or if it’s emulated it can take more cycles. Emulation does work well, even if it often can have timing issues. Some times instructions from a future generation can possibly be emulated on your pc cpu. I can remember my friends computer using an installed windows driver, to emulate a future version of the SSE instruction set, I think it was SSE 2 or 2.1, it worked well enough to play VR games (oculus rift dev kit 1 days).

    Another issue is that when cpu makers deprecate instructions some times, but they do this in a quite annoying way, they can add a wait, so an instruction takes much longer to run than previous cpus.

    I’m not confident enough to talk in this detail about GPUs, because as we all experience, the high level compatibility api like directX or vulkan do all this all the time for us, and I don’t know graphics programming. But I do know this is more of an issue on consoles talking more directly to the hardware. But lots of switch games use vulkan so, those should TM work fine… But some games can also be programmed (intentionally like rogue squadron on GameCube, or unintentionally) to need an unintended or undocumented feature of the vulkan implementation on the switch, and those may or may not work on switch 2

    Nvidia also is responsible for the Cpu design, directly or indirectly. I don’t know how much they care about being as backwards compatible with the cpu instructions as possible though. Probsbly if Nintendo has anything to say about it, they can be 99.999% compatible, with only some timing issues, which may or may not affect games.

    So what is the conclusions? Of course this is speculation, and users have to test games, it will take years to know the full extent, but I think we will see near 100% compatibility for games that don’t need hardware accessories that are not compatible. If we exclude shovelware (low effort crap that somehow got into the eshop) maybe a couple to a handful of games will have big enough issues that they can’t be played. Maybe more games will have minor graphics issues, or things that look fine, but just slightly different to switch1
