After the initial launch, game complains that Ubisoft Connect is not found. After this error message pops up and is discarded, use protontricks to install it.
On rare occasions, a dialogue line would be repeated twice.
Overall good experience.
P.S. Another reporter complained that the in-game shop wasn't working. Since I wasn't using it, I can't comment on this aspect.

Не работает внутриигровой магазин юбисофт, что не критично

Game launches into cropped black screen and then takes 5-10 minutes to load. It works perfectly well after that initial waiting.

Had to install uplay with protontricks. Steam did not install uplay after installing the game

Works out of the box. No issues.
Had a little bit of unsharp graphics. But making the game borderles instead of fullscreen fixed that. (probaly issue cause of my hyprland setup)
My é button did not work in fullscreen but did in borderless. (Probably issue cause of my hyprland setup)
Works, just need to wait for it to fully launch and maybe kill and restart a couple of times on first launch. But after that as long as you wait for the game to fully load before switching windows/screens it all works perfect.
Maybe change to borderless instead of fullscreen when running hyprland as your desktop.

Starts then gets stuck on black screen
Disable Steam overlay, Ubisoft overlay, changed intro videos
Tried every reasonable messure to get it to run and nothing... :/

Ubisoft Connect window pops up first time for login. After this it sometimes pops up to log in again.
Sometimes after resuming from sleep the audio crackles. This can be fixed by restarting the game.
It seems that save file is not consistently uploaded to server. I have had no issues with local saves.
I have graphics set to medium preset with 30 fps cap, this is a very stable 30 fps. Deck can handle high preset with 30 fps but will have a dip sometimes, especially in busy locations.

Em geral, não precisei fazer ajuste nenhum. Somente a questão do mouse que tive problema, mas depois foi resolvido.
Nas primeiras inicializações, tive o problema do menu inicial não detectar meu mouse corretamente. Tive de reiniciar a máquina para identificar e só depois funcionou.

Tried many Proton versions, always boots to a black window
I've tried Proton 9.0-4, 8.0-5, GE-Proton10-4, Experimental, and Hotfix.
Without fail, game shows the title card, then opens another window that captures my mouse (have to Alt+tab) but is just a black screen.
Left this running all night (6+ hours) and managed to get to the warning screen and Ubisoft animation. I never made it to the title screen.
After installing and booting for the first time and logging in to Ubisoft Connect the game boots to a black screen, but after stopping the game from withing Steam, the game boots successfully every time I open it after that.

Game runs smoothly without any significant issues. When starting the game, sometimes cannot pass the loading screen by just waiting. Opening and closing the Steam overlay seems to fix the issue.
Game ran via the Hyprland WM w/latest drivers and patches.

Lowered graphics a bit, or it'd drain too much battery. It looks pretty nice, but not at its best.

Exiting the game doesn't fully close ubisoft launcher, make sure to exit that afterwards.

needed protontricks to install uplay

Using NVK drivers. No either installing or launching the game. Surprising knowing you have to go through Ubisoft's shitty launcher.

Ubisoft Connect seems to have problems saving to the cloud. Nothing else.
Not always hitting 60fps, may be because of hardware, don't really think so. Performance is decent anyway.

Had to disable Steam overlay and use the xbox dongle instead of bluetooth for controller. Once I did that it's fine, it runs better than on my Windows 11 partition.

Super playable after fixing annoyances and major issues, recommend playing on a controller, runs exceptionally well and stable (8GB+ VRAM)
Potential fix for startup hangs: Edit the file ~/.local/share/Steam/steamapps/compatdata/812140/pfx/drive_c/users/steamuser/AppData/Local/Ubisoft Game Launcher/settings.yaml
and set overlay.enabled
to false
, this also get rids of the annoying ubisoft overlays for "This hardware is not supported". Deleting the intro videos folder per other comments is a nice QOL too. Not sure how much disabling steam overlay also helped, but it's consistently booting without issues lately.
Problems with the mouse not being grabbed seems like a Wayland only thing to me (I couldn't reproduce them xorg), at least for NVIDIA. Even fullscreen or windowed mode occasionally opens with artifacts or broken parts here on Wayland. Got a dualsense and swapped to controller only ingame, perfectly playable otherwise.
Had to swap my mouse polling rate to 500 Hz instead of 1000 Hz as it sometimes got stuttery, laggy at random (alt+tab and back, loading a save). Seems to happen more on Wayland than Xorg, but I'm playing on a controler now and it's been perfect.
Two crashes so far inside cutscenes in 40h of gameplay. Not really a problem as restarting the game is fast on a SSD and loads quite close to where you were.

Works as expected. I had issues running it without Proton-GE. Now it works without any performance issues.

It could be a wayland issue but when I switch to another window and switch back to the game, my keyboard input stops working. Only the mouse works. It goes back to normal once I restart my game.

On rare occasions the power-shot sound (sounds like the crackling of fire) would not stop to loop, resulting in a constant background noise. Exiting to desktop and starting the game again fixed that problem.
I have over 200 hours of gameplay in AC:Odyssey and it was fun playing with the Steam deck. Surprisingly even the Ubisoft launcher did not cause any troubles with this game.

Noticeable input latency, but that could just be my setup.
Say what you will about Ubisoft, but their games have always worked very well on Linux for me.
Game sometimes freezes on boot-up videos. Needs to be closed and re-opened several times until it no longer freezes.
Works best with Proton Experimental on Steam

Only tinkering I did was delete the en file in videos, but I also did this with the windows versions.

Controller sometimes stops responding
Aside from minor initial gripes because of the startup movies, the game runs well, assuming you're not using low quality peripherals
Disabled steam overlay. Deleted $STEAM/steamapps/common/Assassins\ Creed\ Oddysey/videos/en/
Game froze on launch without these steps.

The game runs as expected.
Just remember the close the Ubisoft launcher when you're done playing.

Does not need any tinkering, but I use Proton-GE for everything anyway

Assassin's greed + proton + ubisoft cannect not working together
Tried a lot, switching proton-versions, protontricks. Installing the ubisoft connect application with protontricks the game started only once. No second time.

Downloaded game, disabled steam overlay and ran without further adjustments. Full screen resolution, high details, audio and cutscenes work
Had to go to game properties (left click on steam library) and disable steam overlay; as recommended by another user.
Minimal crackling audible during cut scenes.
After disabling overlay, this is a pretty much out-of-the-box experience for me.
The Ubisoft Connect at the start is a bit annoying, but flawless experience after that.

Might need to install Ubisoft Connect from Proton Tricks. Once the game is installed find the installation folder using the command "sudo find / -name "Odyssey". Once in the installation folder go to videos folder. Create a new direcctory called "test" and move all bk2 files into that folder using the commond "mv *.bk2 test". One last thing remains, let's say your language is english, go to the "en" dorectory; create test directory and run the command again "mv *.bk2 test". We are running these commands because the game crashes if the intro video plays, this skips them.
The game will either fail to install Ubisoft connect without tinkering or get stuck at opening videos
after launching the game from steam, - vulkan shaders loading. - game status changes from stop to play in steam, nothing else happening.

gamescope -W 2560 -H 1440 -f --adaptive-sync -r 165 -- %command%
Running with gamescope fixed crashs with intro videos. Ubisoft Connect has to be killed manually.

You'll need to disable Steam Overlay. Otherwise, I ran into a crashing issue that happened 75% of the time. Other 25% worked great. I also disabled the startup videos. Not sure if you need to do that but it was one of the tinker steps I took.

The game is fun, the crashes during intro videos are a nuisance, but you can use the pcgamingwiki article to navigate to where these are and delete or rename them which will solve that crash, or at least get you to the intro screen itself. I have had it crash there a few times as well, with another crash happening during game when i got a steam achievement. I attributed this to the steam overlay being problematic as Ubisoft Connect has its own overlay running (never running properly to be honest) so i disabled the one i could, the steam one, and i haven't had a crash ever since. Plays very well.

Had problems with some new versions of Contability. So I switched to 8.0-5 and it runs fine.

As an NVIDIA user, the key to this one is PROTON_ENABLE_NVAPI=1. I also have to filter the DXVK device to ensure it picks my NVIDIA card.
DXVK_FILTER_DEVICE_NAME="NVIDIA GeForce RTX 4060 Ti" PROTON_ENABLE_NVAPI=1 gamemoderun %command%
The game launches and works fine once you enable NVAPI support. Ran so well I was pleasantly surprised
