EA Launcher won't install with current Proton, Proton GE or Experimental versions for me. There is only a short empty window popping up and vanishing immediately. As a result, the game won't launch, because Steam tries to send a game launch command to the EA app executable in the local Proton installation, which is missing due to the failed install.

Solution: Directly after downloading the game, before doing anything, first let steam check the game file integrity. Then: BEFORE hitting "Launch Game" the first time, set force use of Proton 7.0-6 or 6.3-8 in the game specific steam settings (NOT the global settings!)

If you already attempted to launch with another Proton version and the EA app installer has not been shown, you do NOT have to re-download the game. Just delete the proton compat folder (/home/YOUR-USER-NAME/.steam/steam/steamapps/compatdata/1774580) and then start a new "Launch Game" attempt with Proton 7.0-6. Be aware that any config or save game that has possibly been created and stored locally is gone if you delete the compat folder!

After the EA App is installed, wait for the initial steam setup to finish (it will install a few other redistributables, like DirectX). Before launching the game, it is mandatory to switch back to Proton-Experimental (the game wouldn't launch with Proton 6 or 7, and for me also not with Proton 9 or Proton GE 11 or 14).

After that, i had bad performance ~25 fps avg. on any graphics setting (no change from lowest to highest) and the GPU load on my RTX ADA 3000 (basically a 4070 rtx mobile) was only 45%. I could finally resolve this by manually building gamemode from source code and installing it on the system. See the README in the lower section of the page: https://github.com/FeralInteractive/gamemode, you'll find the commands to execute the build process and install it. Probably, you'll need to catch some dependencies, too.

Voila- stable 55 to 60 fps at all Epic settings, even Raytracing works fine (with the FPS drop that can be expected on a mobile 40W TDP GPU like mine). Overall game performance is now even better than in Windows, but that could also be due to the recent patch 9 on Sept 12th 2024.

Also, before just copying the launching options into your config, be sure to have the applications (like gamemoderun or mangohud) already installed and set up correctly. Using "mangohud" in the startup preset without having it installed manually before will also result in the game not launching!
