I’m on Arch, with Hyprland as my Window Manager. I use an RTX 3070.

For Wayland specifically, the driver was next to unusable for a while. I jumped ship from Windows in Sept. 2023. Beginning with driver 560 iirc, it got a lot better, plus their engineers pushed a lot of changes across the Wayland ecosystem to implement explicit sync support (a net positive, but before this, Nvidia was too stubborn to implement implicit sync, so bad screen tearing was unavoidable). Also there’s been a slow migration to using the GSP processor on newer cards. They claim it can improve performance, which may be true, but I also recently learned it helps them keep some more parts of their code closed-source, which is likely why it’s required to use the open source kernel modules.

At this point, though, it does feel very smooth and I can play games like The Finals at competitive framerates!

But relative to my performance under Windows, it’s still worse, mainly in average framerate. Like others have said, DX12 games seem to be hit hardest. I sometimes have to run lower settings to compensate. Also, if my VRAM gets filled, Xwayland apps all break, so I have to be very careful with higher quality texture quality especially.

Anyways, to answer your question, I think an average gamer doesn’t notice the degraded performance, without benchmarking or comparing framerates back to back— it still runs pretty smooth and framerates are still pretty high. If they aren’t happy with it, they’ll drop quality settings or resolution, just like they’d do under Windows.

Sorry for the late reply. Also @Cricket’s response is great and actually references a source!

Anecdotally though, as a user, I’ve noticed that some things require extra permissions. Usually there’s a prompt from the operating system that’ll ask for permission capture the desktop, which lets me specify which window or monitor to share. It uses the “XDG Desktop Portal”, which was already what allowed Flatpaks to securely access OS resources, and it has a whole bunch of different requests for resources and permissions. It’s similar to a web browser, where it’ll prompt you for privileges when an app wants them.

The hardest pain point for me has been that an app cannot detect keyboard input if it isn’t focused. This could prevent key loggers, but it also makes global shortcuts not work. There is a protocol that allows an app to request a key be forwarded to it, but it’s not widely implemented in apps (discord, for example) and I’ve had to rely on workarounds.

All good! You’re still totally right; outside of the context, Linux has quite the user base with servers, embedded devices, and even phones, if we count Android. I think that’s relevant because it means we can’t rely on “security by obscurity”.

I haven’t heard of any such cases, but it is a smaller pool of users. Also, many desktop Linux users know more about using a computer than other operating system users, since it’s less common for Linux to come preinstalled. So that may affect it, too.

I imagine vulnerabilities with the Linux kernel or common utilities do apply to desktop users as well, which is a good reminder why staying up-to-date is important. But to my understanding, exploiting remotely would need a way of sending data to the target. And most desktop computers won’t have ports open to the internet for anyone like servers will.

I know that Wayland’s design does make it more difficult for a user-mode program to act maliciously, like as key-loggers or reading the clipboard.

I’m sorry to hear you’re having trouble!

Regarding the vainfo thing, at least on Arch, the Nvidia vaapi driver is a separate package. I’m not sure what the equivalent is on bazzite, but that’s likely why vainfo doesn’t show anything. And you should still be able to use nvenc anyways, which sunshine will choose before vaapi.

Is moonlight able to see the computer on your network? And in sunshine’s web interface under the “troubleshoot” tab, there’s a log. Does it say anything that might help?

If you’re feeling adventurous, you could compile Marlin yourself. I did it to use a pin as an “off” signal for my fans, but ended up tinkering with options like linear advance. The set up isn’t too hard, but you need vscode.

That’s awesome! It’s really cool seeing low poly models realized.
