I just retested using Proton 4.2-5. Although #18 has been resolved, the launcher still crashes instantly.

I guess this is the relevant part from the logfile:

Game still crashes because of the full screen mode.

Turn this of like mentioned in protondb works, but no full screen.. :(

({steamlibrary root}/steamapps/compatdata/360430/pfx/drive_c/users/steamuser/Local Settings/Application Data/2K Games/Mafia III/Saves/ and change the line in videoconfig.cfg to "0 0 1280 720 0 0 0 0".)

nooo unplayable.. suddenly runs 2FPS in the "A Friend in Jesus" mission. Before it was playable between 40 and 70 FPS. proton version 4.11-7

steam-360430-2.log

Tested with 5.0-4 but still crashing when trying to launch the game.
steam-360430.log
Tried installing dotnet 4.0 + 4.71 but no luck. Still crashing.

Renaming Mafia3.exe to launcher.exe still circumvents the problem.
Setting following in videoconfig.cfg avoids the hang at start: -6 0 1920 1080 0 0 0 0
You can switch to fullscreen in game but on every new launch the game needs to be in windowed mode or it hangs again.
steam-360430-hang.log

The game is really slow. For me the problem was frame cap was set to 30 fps and vsync on. Once both are deactivated, the game runs 55-60 fps with Vega 56.

Got now the launcher running. Tested with a custom Proton 5.4 build, but I guess that also Proton 5.0 should do.

1. WINEPREFIX=~/.local/share/Steam/steamapps/compatdata/360430/pfx/ winetricks -q dotnet471 (it needs at least dotnet 4.51, so lower versions should do the trick too)
2. WINEPREFIX=~/.local/share/Steam/steamapps/compatdata/360430/pfx/ winetricks d3dcompiler_47
3. (In my case, I also had to disable winegstreamer.dll. Don't know if that's needed everytime.)

From there its easy to configure the game to run windowed. On the other hand, installing that dotnet stuff is a quite heavy, given that the game later doesn't need dotnet at all.

Also heads up, with wine 5.5, the game crashes at start: wineserver: ../../wine-mirror-git/server/thread.c:1309: copy_context: Assertion `to->cpu == from->cpu' failed.

After installing dotnet launcher is fixed, but game did not launch, only process is started.

Hey sorry, it was a little bit to early to say that proton 5.0-5 is working. I actually thought its working but I just tested myself and getting a very similar log like you. So that means you probably need wine 5.4 to run this.

back again.. it worked, now the mafia III definitive edition is released it won't start using proton 5.8-GE-2-MF and proton 5.0-7

Ok update reverted the renaming of mafia.exe to launcher.exe, did this, black screen. reverted the changes in videoconfig.cfg to windowed mode and it starts again.
Only problem now is, setting is back to fullscreen, this works perfect in game, but the game won't start again, next start gives me only a black screen. Too bad since this is the only problem now and was solved for me before the update. Game performance for the rest is perfect on high settings

Sadly, 10 fps on rx 560 on lowest settings/720p

Can confirm that with the new Definitive Edition, the old workaround still applies and works. Sadly you can still only run it in window mode, but you have to have V-sync off and frames set to unlimited or it slows down to a snail pace. You can change to fullscreen when you're in-game but it crashes at a cutscene. On the plus side, mine is running on Proton 5.0-7 and hasn't crashed in a 2 hour session with full high graphics.

Figured out, in-game fps lock is causing massive fps drop, disabling it boosts fps to 60.

Yes, I also figured that out - https://github.com/ValveSoftware/Proton/issues/2142#issuecomment-605524370
Given that also nvidia guys report this, this could be a wine bug.

BTW, do you see any corruption with mesa and especially with ACO turned on?

Yes, mainly with trees, and yes, with aco.

https://gitlab.freedesktop.org/mesa/mesa/-/issues/2768

In my case, the loading icon freezes before jumping to game, I thought it was a corrupted save and tried starting new game, I was wrong. Previous to the game update the game load successfully but the performance was very bad.

Every ty to load the game stops the loading icon freezes the same way.


steam-360430.log

Any one find a fix for the flickering trees on amd llvm or the graphics in aco?

I've sent a patch for DXVK which already got accepted upstream (to my own surprise) to fix the flickering of the trees. Until a new DXVK release is out, you can also just create a dxvk.conf file in game main directory with d3d11.invariantPosition = True which should be enough. This makes the game playable with LLVM backend, didn't played long though.

I see totally messed up polygons, melting and transforming faces with ACO and the problem is still not resolved months after initial report. Unfortunately RADV developer can't reproduce. Means I don't know if it just me or more people effected.

If you guys see the same issue, it would be very nice if you can send a message with your system specs to the report @ gitlab to raise awareness.

I have the same ACO issue (last I checked anyway) thought this was a common issue where do I send the report?

Please drop a message here (with the output of inxi -GSC -xx if possible):
https://gitlab.freedesktop.org/mesa/mesa/-/issues/2768

You can sign in in gitlab using your github account.

do I put inxi -GSC -xx in the launcher flags or is this a terminal command?

This is a small app which every distro should have in its repos. Simply put the command in a terminal and copy its output to your reply.

@kisak-valve please rename the title of this issue to Mafia III: Definitive Edition.

@aeikum @kisak-valve I found in this report https://www.protondb.com/app/360430#TgxHDBqB3a
that the issue with not working full screen has been finally fixed in Proton-6.9-GE1 but it's not mentioned in it's change log https://github.com/GloriousEggroll/proton-ge-custom/releases/tag/6.9-GE-1
so I guess that it was fixed directly in Wine, maybe
in https://www.winehq.org/announce/6.6 in https://bugs.winehq.org/show_bug.cgi?id=43437 (Zanzarah game opens a black fullscreen window and then crashes)
or
in https://www.winehq.org/announce/6.8 in winex11.drv: Correct a full screen condition.

@aeikum I purchased this game and tested it on my own.
When I run the game using Proton Experimental it works correctly in full screen but using Proton 6.3-4 there is only black screen.

This game almost works well on Steam Deck save for its botched Steam Input API integration that leaves the game unresponsive to Steam Deck inputs and causing in-game button prompts show up as "?" or gray rectangles. You can load a template that translates to Xinput but the broken button prompts remain.

my buttons show but they are clustered together, and the UI is overlapping each other.

Game launches with wrong controller setup, which makes it difficult to accept the agreements on first launch. Setting it to steam deck default (gamepad with joystick trackpad) solves this issue. In-game controller icons are missing, this makes it hard to find out which buttons to push for the right action. Icons in the menu are correct. Performance is overall good or as expected, low FPS but good frame times.
