    I had the same experience, but I've had a much better time with software that doesn't go through xwayland, and that's part of what this helps with. I think you'll be pleasantly surprised by games that use a native Wayland path.

    And example is Minecraft. Great on my Intel iGPU and my NVIDIA MX250 under X11, but only the iGPU under Wayland. NVIDIA on Wayland was a slideshow. But when I compiled a newer GLFW and told Minecraft to use it, NVIDIA performance under Minecraft was instantly fixed, it took xwayland out of the equation.

    Fedora 35 and Ubuntu 22.04 and newer have native Wayland libraries that will drastically improve things for gamers, and this will help legacy games 'short circuit' around the xwayland shortcomings.

    Even with that being the case, that's entirely NVDA's fault. It is a tremendous failure of theirs that they have to spend money hiring software developers to work around deficiencies and software they themselves publish.

    Yeah, go ahead, make me feel even worse about this.
    The real answer is price, though

    That's exactly the spot where GameScope will come to the rescue to make them play super-fast again...

    I did it for https://folding.lar.systems/gpu_ppd/overall_ranks

    Gamescope is what I actually miss after switching from AMD. It was one simple trick to run a game with problematic fullscreen or avoid stutters when running in non-native resolution.

    This is a good thing as they might possibly improve the Wayland support in their driver overall. I keep my hopes low, though.

    I guess the FD limit thing is fine, but why do they need so many file descriptors?
    There are many reasons for needing large numbers of file descriptors, most of which apply with upstream drivers as well. E.g. every buffer shared between the Wayland compositor and a client is represented by a file descriptor.

    The broad summary of what's going on here just sets off my code review spidey senses lol.
