Some levels have minor performance issues, Citadel is slightly choppy when entering rooms with a lot of NPCs. So far after 8h one of the planets had major FPS issues. Rest worked flawlessly. Only played ME1 so far.
Some occasional performance issues, but they could be caused by this being an old game. Haven't had problems with EA, left it on.

Perfect out of the box. 4k resolution.
I only played ME1 for two hours. It is perfect out of the box, at 4k resolution.

Added holster button.
Launcher must be run at least once in desktop mode.
Some text may be difficult to read for visually impaired people.
Recommend setting max FPS to 45 for framerate stability.

Did not try without launch options. Worked without any issue and performed flawlessly. There was about a 30 - 45 sec black loading screen with audio after selecting one game from the 3 available games.

the ea-app installs fine with proton 7.0-6 after the game stopped (crashed) it runs fine with proton experimental or ge 9-26

just the loading time takes a little long it could be useful to delete compatdata at the beginning

Finished all 3 games. Sometimes the games don't start (EA Launcher fail to start), but usually i simply restart it and it runs.

Doesn't launch
Shows EA loading bar and than just exits.

Game still has bugs from original ME3 like the shield bug. Simple fixes below resolve issues. Gamescope fixes 60 FPS limit bug.

Disable both Steam and EA overlays. Steam can be done via the game properties in Steam, for the EA launcher you have to edit the config file located at "~/.local/share/Steam/steamapps/compatdata/1328670/pfx/drive_c/users/steamuser/AppData/Local/Electronic Arts/EA Desktop/user_********************.ini". The .ini number string is 20 characters long and is unique to your own EA account. Add "user.igoenabled=0" to the end of this file to disable the EA overlay completely for ME LE.
Mouse sensitivity is still tied to FPS, an old ME3 bug. At higher rates than 60 FPS, mouse sensitivity will slowly decrease the higher the FPS goes. At higher FPS limits like the recommended max 144 FPS, you may have to increase sensitivity ingame, just adjust to your preference.
First, without gamescope, game was limited to 60 FPS max no matter what settings I tried in game. Also, the old "shield" bug from original ME3 release is actually still present even in the LE version, but instead of 60 FPS, the new limit is 144 FPS. Setting the FPS limiter in the game higher than 144 FPS will result in slow shield recharge, and enemies being able to aim much faster. Game logic is still tied to FPS. Simply disable vsync and set the in game FPS limit in settings to 144 (or whatever is lower than your monitors refresh rate!) to fix the bug.
Without gamescope, game feels stuttery even at the 60 fps limit. Gamescope fixes this, and game runs flawlessly on my hardware in all 3 games at 144 FPS. I have completely beated ME1 and ME2 in linux, and am playing ME3 now. Also ensure you force proton experimental otherwise ME3 will freeze on launch with blackscreen if you use the default proton-cachyos, ME1 and ME2 were not effected. In launch flags, "-game 3 -autoterminate" will skip the game launcher entirely and load directly into ME3, and then exit to desktop on quit. Change the number in the launch params to whatever game you are currently playing.

Launcher would not always recognize input
Small text
Some audio would cut out completely if you stayed in a conversation too long.
Can only use one input at a time in launcher. Make sure to set as priority controller
Games played at 900p with FSR enabled.
45fps, 9Watt limit, lowered resolution to 960 x 600 and used fsr at sharpness 3.

Runs flawlessly with no issues. Sadly the EA launcher popup breaks mangohud, so no FPS or frametime statistics because of DRM.

Game runs fine on default proton, no need to run on CachyOS to get it to run.

Massive stuttering and frame drops occurred randomly.
The game required several launches to get the EA launcher working properly, so don't be dismayed if it doesn't work the first time. The only major downside is massive frame drops and stuttering, but I believe this to be a problem inherent to Legenary Edition even on Windows. It runs well with both Proton experimental and GE.

Just deactivated the EA-App overlay via configs
I had 2 crashes in 50 hour

It was very difficult to navigate menus and control the game with mouse and keyboard.
Initial cut scenes stuttered badly, game appeared to run with very low FPS, but GPU usage was below 5%.
The problem was a Logitech USB joystick that was unused, but plugged in. I unplugged that, and the game is running great with mouse+kbd. I've never had a game behave like that.
gamemoderun %command%

Completed ME1 and ME2. Zero issues. Started ME3. Seems to be working flawlessly.

Worked almost perfectly with no tweaks.
Initially, frame rate was bad, and fiddling with graphics settings in game did not help. I've learned by now, though, that I just have to start the game up, then exit out (just to the EA launcher), then start it again, and frame rate is just fine, even at max settings.
Wouldn't launch on Windows 11 for me for reasons I still don't understand, but ran with no problems out of the box on Kubuntu 24.04

Haven't Completed the first one yet. So i haven't tried 2nd and 3rd game yet, but first one works flawlessly.

The EA Launcher wouldn't install with Proton Experimental. With Proton GE, it installed, but wouldn't open.
gamemoderun %command%
Neither the EA launcher nor the game opens on my setup.

I directly opted to use proton-ge but probably valve's recommanded proton version - experimental would also work fine I think. The necessary EA companion app installed and runs fine alongside the game. When the game is running, I even get a virtual windows system tray on my sway wm environment to access that EA app if it's ever needed for some reason.

EA Install Script took a long time but it worked.
With GE-Proton9-20, EA App would start, but I'd get the Error Message "Failed to Launch Game".
Tried fixing it by installing EA App on Lutris, which led to another Error of some Port 32** being blocked.
Tried Proton 9.0-3 and 7.0-6 next, both didn't work.
Finally I tried Proton Experimental, which just skipped the EA Launcher entirely, and the game now works. The weird thing is that now that the game started once with Experimental, it ALSO WORKS WITH GE-Proton. Whyyy? I don't understand.
Tl:dr try Proton Experimental first, then after that your version of choice.

gamemoderun %command%
Game frequently crashes on startup, sometimes several times in a row, likely due to the EA App. No crashes or stability issues once the game decides to actually launch.
Aside from occasional crash at launch, the game works fine and stable. Save transfer between individual ME games works without any issue.

Cutscenes and talks cause significant CPU temp increase
EA Launcher would not start game with Proton experimental. Switching to GE-Proton fixed this

Was able to get fullscreen working after changing the resolution and restart
After fixing the resolution the game starts without any issues
Mass effect 1 will show "Loading" while playing the game a lot, gets annoying but not unplayable.

Using Proton Experimental, EA's launcher was unable to install and run. Switching to Proton 7.0.6 helped.

gamemoderun %command%
Everything works

Plays nicely.

This GE version solves the EA app install issue. Make sure you use the launch options tho.

All 3 games works quite well. There were some issues with the EA App.
The EA App sometime causing the game launcher (LE) to not launch.
Played all 3 games without significant issues. There were some minor issues: characters get stuck in textures when using elevators in ME1; cut-scene/next objective didn't start after cleaning a level in ME3. But I think that's game-related bugs, not the proton.
Sometime EA app could not launch the game (LE launcher). It happened in scenarios like: EA app update, user was logged out from EA app, the game crash/force exit. I made a copy of proton prefix's files for modding purposes. So if some issues occurred with EA app, I use that copy to revert changes and fix it.

Mass Effect 1 and 2 work flawlessly OOTB, no tinkering needed.
I've played both games, 1 to the end and 2 halfway through, no problems at all on either. The EA app sometimes doesn't start and you'll have to shut down the game from Steam, then re-open it, but that only happens rarely. Save games also work fine with the cloud, I had to uninstall the game temporarily for something else and I didn't even have to log back into the app when I reinstalled the game. Perfectly seamless.
steam overlay off

Worked out of the box
No problems with EA Launcher. No tinkering needed

Stuttering/FPS drops
Tried different Compatibility settings in this order: GE-Proton9-12, Proton 9.0-2, Proton Experimental, Proton 8.0-5. None of these worked as they were all stuck at EA Install. Only Proton 7.0-6 passed EA Install and the other installations before finally working. There is stuttering like other users have reported, which should not be my hardware's fault given it can run BF1 on 60+ FPS without drops.
