Yes, im having the same issues since jun/jul (i cant be sure) sometimes the game enter with a neat 99fps sometimes is 10fps, but nothing in between, also audio glitch i mean music stop playing for good, or sometimes it sounds like lagging (Even in the loading screen) but isn't an connection issue, everything get fixed closing and opening again , sometimes i need to restart the computer to get ride off this bugs.

I'm using Steam on Mint, not forcing any particular proton version.
Nvidia 1070

(Posting to this thread as it is the latest about running on Linux)

My experience with non-store version (i.e. Bethesda Launcher vs Steam/Epic/etc) on Arch Linux with Gnome DM.

I use https://github.com/Open-Wine-Components/umu-launcher to start it under this version of Valve's Proton: https://github.com/GloriousEggroll/proton-ge-custom/releases. (AFAIK, it should be selectable in Steam Launcher somehow)

Just recently GE has released a version with experimental Wayland support, and it works! (Although, somehow, I can get to the char selection screen only every other time). There seem to be no difference in the picture, and now that the Xwayland is gone, input lag should be gone as well. Oh, actually, under Wayland the Bethesda Launcher is less laggy.

EDIT: Well, no, Wine-Wayland doesn't work well. After a couple of minutes the graphics hang up, while audio is still being played.

A couple of years ago network seemed to fare better under Linux, but now, going across the ocean, it sucks anyway. Graphic performance was a little bit worse, but they've added some kind of buffer sharing, and it should have been the same since then. Even more certainly so, if you manage to run without Xwayland. That said, even with it I've managed to do a HW-accelerated (iGPU) screen grab @60Hz with the game running at high quality setting on a laptop 3070 (dGPU).

- Does anyone know how to start the game with console output? (So that I can file a decent bug report)

https://github.com/Open-Wine-Components/umu-launcher suggests using some env variables, but I'm not sure if Steam itself will react to them.

General survey on Proton users:
- Does it run well for you?
- Do you use Nvidia?
- Do you use Wayland or X11?
- Is performance on par with windows?

- Yes, very well. I can do everything I was able to do under Windows. (Although the hardware might be hiding the issues)
- Yes, in hybrid setup, i.e. in GBM Wayland mode.
- now Wayland exclusively (although XWayland still runs in the background for no apparent reason).
- I guess so - I didn't launch it under Windows for a long while.

This game was running on Googles Stadia servers which were Linux machines with Vulcan. Does that mean that there is already an existing Linux version? If so, could you make it avilable to players?

AFAIK, Stadia was using Wine.

Works for me very well on Linux, but I have occasionally had screen stutter, which can also seem like low FPS. Whenever this happens, I make sure to update all packages, including latest Nvidia closed driver and Steam. Then I reboot just to make sure (probably not necessary). After that, the game always works again flawlessly, so I imagine it has to do with some mismatch of the Proton Experimental/Hotfix branch and my other packages.

Also, if (like me) you tend to launch directly from eso64.exe, make sure you also occasionally open from the launcher as this is the part that prompts the Steam compatibility library to update its shaders for ESO.

ETA: I consider ESO working way better on Linux than Windows, because when I ran it on Windows, the cooling management software (Corsair iCUE) would hang without me knowing and cause the computer to overheat. I have a basic AIO CPU cooler, and the fans run slowly when the PC is idle, and they speed up when needed when the CPU is actually under some load. When I started ESO, I would have to remember that sometimes (not always) the iCUE software would hang without throwing an error. So I would have to remember to manually force shut iCUE and start it up again after launching ESO. I'm not sure if this was caused by some sort of low-level anti-cheat detection or what. But it was super annoying, and more than once I would of course forget, only realizing after my computer overheated and started flashing red on the motherboard. Not great.

GloriusEggroll and Etaash Mathamsetty have really improved native Wayland support since I last tried it. The game doesn't crash mid-flight any longer.

Additionally, the broader community developed a fix for games hanging up while their windows are hidden/occluded/not on the active workspace, culminating with the freshest nvidia driver supporting the fifo-v1 Wayland protocol! If earlier I needed to turn vsync off, bump display refresh rate to above 100Hz, now everything is working fine at 60Hz! (I've also switched to running in-kernel nvidia driver, but I don't think it is the one responsible. Nowadays it is more of an interface for what is coming in nvidia-utils.)

In 2025:

- Does it run well for you?
- Is performance on par with windows?
Yes, on par with Windows.

- Do you use Nvidia?
No.

- Do you use Wayland or X11?
Wayland, I'm getting better I/O performance than X11 or even Windows. Minor flickering issue on load screens with Freesync.
