Works perfect out of the box. In 34+ hours of playing I've only gotten some minor texture errors (bottom of some environmental textures on one map were faded into a blue color) once. Just once, on 34+ hours, and even then it didn't happen twice on the same map so it may not be linux related.
SP simply works, no tinkering at all. Haven't tested online.

Shader building took some time
Crashes without crash log, no way to find a reason

gamemoderun %command% -useallavailablecores
mv TaleWorlds.MountAndBlade.Launcher.exe TaleWorlds.MountAndBlade.Launcher.exe.backup && ln -s Bannerlord.Native.exe TaleWorlds.MountAndBlade.Launcher.exe
Just rename the launcher with the command mentioned above (of course, first cd into YOURINSTALLPATH/steamapps/common/Mount & Blade II Bannerlord/bin/Win64_Shipping_Client). Works great, even faster than on Win10.

[Heavily modded playthrough] Runs like a dream, even after adding a ton of steam workshop mods.
I have seen some very rare occurances on some maps where some textures will have near the bottom a blue tint. Keep in mind, it's happened 4 times in over 166 hours
Crashed roughly 6 or 7 times
Matchmaking is a coin-toss between finding an actual game or staring at the loading screen infinitely.
Using GNOME 47.3 (xorg)
I've also played roghly 20 hours ish of vanilla with no issues.
Works out of the box. Better than expected performance for me

Works great for me.. just as smoth as windows.

On first run the frametime is horrible after logging in. Logout and start again it will work fine
gamemoderun %command%
MULTIPLAYER ISSUE: on first launch the framerate is super inconsistent. Unplayable

Honestly runs better than on windows 10. Saving and loading into areas and the map no longer take very long.
9.0.3.

Turn off the steam overlay
FPS tanks on some locations below 30, but It may be the common issue with Windows
Steam overlay causes frequent crashes, so you have to turn it off
With STEAM OVERLAY turned off the game never crashes, but the performance sometimes is sub-optimal even on the lowest settings (lowering graphics or crowd doesnt really help) but as I said it could be a common issue with Windows

The game is running fine with proton but make sure to meet the required components to run it without issues
Lags during battles due to my computer's poor perfomances

works fine
On the past it has very slow save games, currently version works fine

The frequent crashes make the game nigh impossible to enjoy at points during mid-to-late game where troop count tend to be in thousands.
Simulation for cloth physics, specifically on banners in battles, goes crazy.
Game continously crashes during large scale battles, more often than not during sieges, I suspect the mentioned cloth physics artifacts are the main cultprit as they are tied to the physics engine.
Admittedly, I did play on highest battle size settings which may have exacerbated the physics and subsequent crashing issues.
Works pretty good out of the box, I just had to turn the settings to medium for my hardware.

Works fine as long as the Steam overlay is disabled.
Game freezes when doing anything with the Steam overlay, including getting achievements. Had to disable the overlay.
Works great out of the box. No issues besides the occasional crash when playing for 6 hours straight.

To use mods:
Run protontricks -c "env" 261550 | grep "WINEPREFIX"
and you'll get something like WINEPREFIX=/path/to/SteamLibrary/steamapps/compatdata/261550/pfx
. Copy and paste it and add winetricks dotnet472
. Your command should look like this: WINEPREFIX=/path/to/SteamLibrary/steamapps/compatdata/261550/pfx winetricks dotnet472
(you have to change the path to the one you get from command of course)
Then paste it again and add winetricks vcrun2017
, then again adding winetricks gdiplus
(this one will take a while!)
Installing dotnet using protontricks has been failing me for a long time, even if I go back to proton 4. But it works using winetricks.
If you want to play with RBM (Realistic Battle Mod), you have to also instal the Harmony mod, and it will start working.

I had an issue where the game crashes randomly when entering or leaving combat. I believe it had to do with .net 472, but I am not certain.
The issue was resolved after steam randomly reinstalled "steamworks redistributables" for the game.

The game was running flawlessly until a week ago. I think an update to video drivers has messed something up.
Crashes when entering or leaving combat. The game works fine on the world map

Crashes resulting in a loss of unsaved data.
Crashes Frequently. Once it even froze the whole system.

Unable to launch new campaign - crashes after character creation. No rendering issues - stress test runs ok.
Tried "cabextract" method mentioned in Proton issues page
Not playable.
Game kept crashing on start (before the main menu). Disabling the steam overlay solved it.

Works perfectly with Proton-GE. Also no problem launching with Experimental and Stable, but I didn't play that much on those versions.
Shift+Tab overlay crashes the game.
Some mods may not work. I personally tried Calradia Expanded, and it crashed on "New Campaign" no matter what. I switched from Wayland to Xorg, changed Proton versions between GE, Experimental and Stable, disabled and enabled MangoHUD.
I am currently using Dismemberment Plus, Harmony, ButterLib, UI Extender and Mod Configuration menu. No problems with these mods.
Works perfectly aside from occasionally requiring multiple attempts to launch

Steam overlay causes the game to freeze when opening steam overlay or receiving an achievement. Disabling steam overlay fixed it. Note that I had to enable steam overlay globally in the Steam -> Settings -> In Game section and then disable it specifically for Bannerlord in its game-specific properties under General to fix the problem for me.
Pretty easy to get working at 100% functionality, but I definitely recommend disabling Steam Overlay to prevent issues.

gamemoderun %command%
Crashed everytime I got an achievement, fixed by turning off In-Game Steam Overlay.
Other crashes I experienced are known bugs in the game, unrelated to Proton.

Runs perfectly
It just works (lol)

Multiplayer works as expected, however, the menu to select custom servers is very slow to load (20s).
The game runs well in single and multiplayer. I did not experience any issues aside from the mentioned long server selection loading.
Unplayable since latest update
Tried several versions of Proton, Proton Experimental, GloriousEggroll
Played 400+ hrs with GE 7.2 last year. Since recent updates (1.2.7 to 1.2.9), it doesn't launch anymore - tried every Proton, Experimental, GE version you can think of. Nothing works.

Ekran Kalibrasyonu Ekranında Kaldı
gamemoderun %command%
Başta oyunu açarken bilgisayarın fanlarının hiç dönmediğini gördüm. Oyun yükleniyor ekranında takılıyordu. NVIDIA kartının çalışmadığını tahmin ettim ve tahminim doğru çıktı. XFCE'nin compositor'unun bu konuda sıkıntı çıkardığını öğrendim ve devre dışı bıraktım. Ekran Kalibrasyonu menüsüne ulaşabildim. Fakat bilgisayarın Num Lock tuşu dahi çalışmıyordu.
(Oyun müziği takılmadan arka planda oynuyordu)

Works perfectly after disabling Steam overlay
At first the game wouldn't load for me but after disabling the Steam overlay, as mentioned in some other reports, it works perfectly in singleplayer. I've played for many hours now without any issue. Haven't tried the multiplayer.

Disabled steam overlay
opening steam overlay or even getting achievement freezes the game
Used the MO2 installation script with a custom game config. Installed dotnet using Proton 4.11 up to and including .Net 4.5, then changed Proton to 6.3 to install .Net 4.6 through 4.72. Then changed back to GE8-23. Installed BLSE (https://github.com/BUTR/Bannerlord.BLSE) manually into the game folder and Harmony, ButterLib, UIExtender and MCM through MO2. This leaves you with a fixed base install. You launch the game which opens MO2 where you can start BLSE to run the game.

Even though it freezes for me, many others report no issues. And if you stick to 1.1.6 or lower it seems to be more stable.
The video will hard freeze after a random amount of time. This is unrecoverable - I have to shut it down in Steam and restart. Sometimes it happens on the main menu, but usually it happens after the game loads while on the map, in the Trade screen, the Smithy screen, or the map. It very rarely will freeze while in a battle. It immediately freezes when I press F12 to take a screenshot. When the video freezes, the audio continues to play. It can take anywhere from a few seconds after loading to many minutes or over an hour before the freeze happens. These issues only started with version 1.2.x. I had no issues with 1.1.6 or earlier versions. I also have these issues with the perf_test and perf_test_beta beta versions. I also discovered that if I reboot for some reason it will take longer before it freezes the first time.
