Enjoyable experience in game
During the credits roll and during a cutscene or two there would be an artifact
Very occasional crashes
The EA launcher is annoying and gets in the way

At 60fps battery lasts about 1.5 to 2 hours. To improve battery performance lower to 40fps
Can't sync ME2 save file
The game itself runs very well with Proton. If not for the Origin client, the experience would be flawless.
I disabled all the notifications in the Origin client. Otherwise, every time an achievement notification popped up the game window was minimized. Not critical, but pretty annoying. Especially during combat.
I recommend disabling the notifications in the Origin client. Otherwise, every time an achievement notification pops up the game window will be minimized.

It run's through origin which can sometimes cause problems. After 20h of successful play, it suddenly stopped launching. I had to go to the proton prefix and delete ProgramData\Electronic Arts\EA Services\license directory. The problem has nothing to do with linux or proton per se.
Works OOTB on Proton Experimental, seems to not be affected by low FPS issues that Windows experiences with the Origin Overlay.
Issues in regards to the PhysX installer are now gone.

Had to execute "winetrix physx" manually to install Physx

Large Address Aware Proton launch option is set to keep audio from falling out of sync during cut scenes.
On dual monitor setup, I had cursor on the wrong display
Game works out of the box with Proton 6.3 or Proton Experimental. This is now a Platinum game.
Sometimes mouse-clicks are not registered correctly e.g. on the galaxy-map, but exiting and reentering fixes it.
First startup used a low resolution until I changed it in the settings and restarted the game.
Origin achievements are unlocked right away but the Steam achievements are only unlocked the next time the game is started.

Follow my guide on GitHub, i am now able to run Mass Effect 3 directly on Steam by just pressing Play.

Tried every possible solution mentioned here. The game won't launch or is not installable (through Lutris Origin for example).
I recommend waiting before buying this on Steam at least.

EA Play on Steam. Game install / Origin Launches but game doesn't run.
I installed the EA Play version. The game installs and Origin launches however Origin shuts down and closes down the game before it launches after a dialog box pops up to tell me that my hardware doesn't meet the minimum requirements.

Downloaded via Lutris-Origin
Some missing textures but barely noticeable
Occasional lag spikes during cutscenes
On single-player, Game crashes when disconnected from EA servers. Could be caused by DLCs as they cannot be verified

Plays well with few issues
Some missing textures but its not that noticeable
Occasional lag spikes during cutscenes
On single player, game crashes when I lose connection to EA servers. Probably caused by DLCs as they cant be verified
Installs and Origin opens. PhysX error. Not playable at all (game won't open)

protontricks 1238020 physx
The problem is that proton DELETES physx files every time you launch it with steam (check the wineprefix and install all necessary things), What you need to do in order to play it is: installing as normal with steam, then let it run and say yes to the physx error, then install protontricks and run in your terminal: protontricks 1238020 physx Now DO NOT press play on steam Run mass effect 3 with wine selecting the prefix, type in your terminal WINEPREFIX=~/.steam/debian-installation/steamapps/compatdata/1238020/pfx wine MassEffect3.exe Now it should work :)

Origin is installed as it should... but no luck with ME3
Game doesn't starts up and after successful login to origin yields an error:
failed to initialize the physics system please ensure you have an updated version of the physx system software installed
I've tried with protontricks to:
- install PhysiX engine
- force 32bit arch
Still same error is present and game doesn't start
Used 32bit prefix with winesteam, worked without any problem that way. Uses lutris-5.7-3-x86_64

Borked due to Origin
Tried with both:
Proton Version: 5.0-9 Launch Options: None Proton-5.9-GE-3-ST GloriousEggroll
Proton 5.0-9 - loads Origin but gives a stucks on physx error before even loading the game GE never loads after attempted install of Origin thin. Tried both via Lutris as well as the Lutris proton version (latest only)
Did not work for me, attempted manual install of missing physx as stated below but no difference unfortunately.
Would probably be easier to get a cracked version working than the legit version.
I did see on the GitHub that someone got it working on Steam for Windows (32 bit) via Lutris, but I do not know if that is a solid fix for everyone.

Might try the above if my windows VM is too sluggish.

Does not run
I can't run it with proton 5.0-9 (stucks on physix) or Proton 5.11 GE 2 MF-1 (processes stopped working on startup without any graphical output)

Proton-5.11-GE-1-MF GloriousEggroll
in Lutris change Origins' runner to Proton-5.11-GE-1-MF and :
Under "Runner options":
- Enable VKD3D
- Enable Esync
Under "System options"
- Enable the "ACO shader compiler" option
Occasional yet small amount of stutter in cutscenes along with minor flickering at the very top of the screen while on Mars until I got indoors.

Wine missing physx-Driver
pretty much the same as the others.... wont even detect manually installed physx-driver

Game crashes, cites PhysX error.
Hopefully this will be fixed when Proton merges with Wine Staging.
Origin installed and it complained that it could not install the game in the folder.

Installed successfully, including Origin, but game dies with PhysX error
The full error (pops up in a dialog): Failed to initialize the physics system. Please ensure you have an updated version of the PhysX System Software installed.
Proton Version: 5.0-9 Launch Options: None
I installed PhysX via protontricks (protontricks 1238020 physx) but the problem remained. I also installed PhysX manually, but that didn't help either.
