This has been raised before, can be fixed by manually installing older version of uplay into the prefix and then changing the version number. https://www.reddit.com/r/linux_gaming/comments/a8f2kl/proton_3166_beta_released/ecbdi99/ Not a nice fix, but a fix at that.

I've managed to get this game running after doing the above steps, but am now encountering lack of audio and a rendering bug, I've uploaded the video of my issue here: https://jackryder.co.uk/stuff/far-cry-rendering-bug.mp4

@kisak-valve would my issue be best in a separate issue? Didn't want to create another open issue for the same game.

system info :https://gist.github.com/JackRyder/d706d3038a2b8893595214a95e930045

Since the game runs, the proton log is pretty hefty so I split it into two parts, I imagine the second part would be the best for infomation, but i'll attach both anyway.

steam-298110B.log

Also using proton 3.16-6 Beta.

I was able to get it working with Proton 3.16-8 Beta, and I got sound working too. I achieved this by using protontricks to run winecfg and add FarCry4.exe with the compatibility mode set to Windows XP, then using protontricks to install xact. Now I have an issue where the game is freezing every few minutes. This is because I'm on Ryzen isn't it? The issue reminded me of another issue I had with other Dunia Engine games on wine-staging because I had too many CPU cores. This is definitely not the culprit (and shouldn't be since esync is enabled). The stuttering seems to be caused my me rapidly moving my mouse. Any ideas? I plugged a different mouse into my computer and the freezing went away. Thanks Corsair.

Had the same mouse problem but disabling Uplay overlay fixed it..!

With Proton 4.2-4 the game working with follow issues:

1. No sound after first cutscene, this issue can be workarounded:

• $ WINEPREFIX=~/.steam/steam/steamapps/compatdata/298110/pfx/ winecfg
  and set Windows Version to Windows XP
  
• $ WINEPREFIX=~/.steam/steam/steamapps/compatdata/298110/pfx/ winetricks xact

1. Appearing on random locations rectangular dimming in game:
   
   How it looks in dynamic I demonstrate on Youtube video: https://youtu.be/6O_LUtFXP58

2. After switching to another application and returning to game by pressing "Alt -Tab" unable rotate protagonist on 360 degrees (only 180 is possible), this issue can be workarounded if in main game menu (Escape button) and select "Resume" item.

3. Not working gamepad in my case it Dualshok 4

Gamepad controls are not recognized in the game...

Also all foliage appears flickering

To fix flickering foliage, install/compile dxvk 1.4.4 or less for now.
Related: https://github.com/doitsujin/dxvk/issues/1257

I've bisected the flickering issue, it's caused by this commit in DXVK.

As Far Cry 4 was on sale I got it. Works with an nvidia card as far as I can see. The audio issues still exist but can be worked around as previously detailed.
I would like to get the controller part to work though. Any ideas how to go about it? The initial menu react to controller input but seem to misinterpret the input. This probably leads to controllers being disabled.
Any ideas how to go about debugging this? I'm not very experienced with wine/proton debugging.
Searching for this issue I see that Far Cry Primal also has trouble with controllers, same issue maybe.

Far Cry 4 don't run. Uplay run correctly without any problem, but when I click play on Far Cry 4 it didn't run

I've bisected the flickering issue, it's caused by this commit in DXVK.

Have you reported it to DXVK?

Have you reported it to DXVK?

I wrote a comment about it in the Far Cry Primal issue (https://github.com/doitsujin/dxvk/issues/1257) because that seems to have the same problem. Unfortunately they don't really know what's causing the issue, and are not really interested in fixing it(see https://github.com/doitsujin/dxvk/issues/1257#issuecomment-558790007)

Unfortunately they don't really know what's causing the issue, and are not really interested in fixing it

from the later comment it seems like it you tracked it down pretty closely. I guess the next step (unless someone spots the issue) would be to look at the disassembly (ghidra has a diffing mode) with and without the call. not in the mood to wade through x86 assembly now, though.

it seems to work fine with Proton-6.0-GE-1

It seems msmpeg2vdec.dll is part of the Windows Media Feature Pack which led me to a winetricks github issue. that can not be linked here

It seems this is a really old issue which makes me think it is not the reason Far Cry 4 is not launching for me because it clearly worked several months ago.

I did some testing on this...

Ubisoft Connect does not work on Proton 5.13-6 or older. So that leaves only Proton 6.3-7 and Experimental.
I tried fresh installs of Pop!_OS, Manjaro, and Garuda Linux. All the the same issue.
Either Far Cry 4 works on an older Proton Version but Ubisoft Connect won't work on or this is a specific issue with my hardware config... 5950x and a 6900xt
Looking at ProtonDB I can see that this was working on the latest Pop!_OS with Proton Experimental 2 months ago with a Ryzen 5 2600 and Nvidia 1650 so perhaps this is an AMD GPU issue.

It has been months now and I am still having this issue and over these last several months I look at protondb and I see random people also having the same experience as I do appear either the game runs great or it never launches. Does not seem to matter what hardware brand you have, what version of proton you are using, or what linux distro you are on. Either you are lucky and it works or you are not lucky and it doesn't launch past UPlay. I tried multiple distros both debian and arch based, tried multiple Proton versions including experimental bleeding edge, as well as tried removing all DLC and just running the base game.

Try using the GloriousEggroll proton versions, they work better with 3rd party DRM

I have been, just tested it again with the latest version. No change on the issue. Also just tested with Resizable BAR disabled. I can see plenty of people reporting they are using official versions of Proton without issue as well.

Edit: Also for clarity all my other UPlay games work fine. Several Assassin Creed games, Watch Dogs, etc. So definitely an issue specific to Far Cry 4.

I'm in the exact same boat as you @ChaosBlades I've got an Nvidia system, Farcry 5 works no problem, Farcry 4 refuses to launch.

I have finally got this game to launch on something. I am now fairly confident this is some kind of hardware specific issue. I installed ChimeraOS 33 on my living room PC and the game works without issue. I then install ChimeraOS 33 on my desktop PC that I have been having this issue on and just like with every single other distro I tried it will not launch. Here is the hardware breakdown on both systems.

Living Room PC (Works)
CPU: AMD 5800X
RAM 32GB DDR4
Mobo: ASUS TUF GAMING X570-PLUS (WI-FI)
GPU: Nvidia GTX 1660 Super
Storage: PCI 3.0 NVMe SSD

Desktop PC (Does Not Launch)
CPU: AMD 5950X
RAM: 32GB DDR4
Mobo: ASUS ROG Crosshair VIII Dark Hero (X570)
GPU: AMD 6900XT
Storage: PCI 3.0 NVMe SSD

Based on my research I can not find anyone reporting this game to work on any CPU that has more than 12 cores 24 thread. Every reference to this game not working with a CPU model listed is reporting they have a 5950X that I am able to find.

@makeclean What CPU do you have?

I went into the BIOS and limited the CPU to 1 CCD (8 core 16 thread).... Game Launches!

That is the issue, it is some kind of core count limitation.

Now that we have identified the issue can we get a developer to look into this? Let me know if you need any logs or anything from me. I did post a log back in Sept of 2021 but if that isn't enough let me know.

I'll also update my report on protondb to reflect this issue.

Does it work if you launch the game with WINED3D?
I have already made a dxvk issue since i noticed i got stuck in the pre company logos loading screen 1/2 times with dxvk, but not with WINED3D.
The game have apparently been finicky with dxvk in the past.

I added PROTON_USE_WINED3D=1 %command% to the launch options and no it does not launch. Same result as before.

That also does not work around the issue. Also tried different variations on that such as the following.
taskset -c 0,2,4,6 %command%
taskset -c 0-7 %command%

I just disabled SMT (disables Hyperthreading) in the BIOS which turns the CPU into 16 Core 16 Thread (instead of 32 Thread). This also allows the game to launch.

Edit: Limiting each of the 2 CCDs to 7 cores (14 Core 28 Thread) also allows the game to launch.

Edit2: I would just like to state that the game does work running on this same system under Windows. Seems on Linux via Proton we have a Thread limit somewhere between 29 and 32 threads and artificially limiting that via taskset does not work around the issue.

Good investigation Chaos 👀

My email reply didn't make it to you @ChaosBlades but amazing sleuthing. I have a dual socket 32 core (64 threads total) machine, which corroborates this. Amazing work.

I wonder if its worth trying numactl- https://serverfault.com/questions/625146/difference-between-taskset-and-cpuset maybe?

Assuming I did this correctly, that does not allow the game to launch.

cpuset and numactl is not installed by default on Pop OS so after installing them both it looks like cset by default already sets up a cpuset containing threads 0-31. So I should just need to add numactl --physcpubind=+0-7 %command% to launch options and that should limit the game to CPU cores 0-7, which did not allow the game to launch. UPlay does launch which makes me think it is working, but I get the same behavior as before.

Similar issue here https://www.protondb.com/app/55150 reported by synrgy87, seems to be a theme with high core count machines.

It would be nice to have a software solution to this :)

If it works on windows then i imagine a software workaround or fix should be possible.

Note even after this has been fixed the game also is a bit iffy together with dxvk and can randomly freeze at boot at least. Dunno about ingame

I own Warhammer 40,000: Space Marine - Anniversary Edition as well and tested for this issue.

On failure it will launch to full screen (black screen) unlike Far Cry 4. It will then crash to desktop with a Bug Splat error window. Where it wants you to send in a bug report.

On this game I needed to limit the CPU to 6 Cores per CCD. So 12 Core 24 Thread. The game would not work on 14 Core 28 Thread like Far Cry 4.

I'll post in the issue thread for Space Marine as well looks like they don't understand what is going on over there yet as well.

@ChaosBlades I just learned of WINE_CPU_TOPOLOGY which is built in to protons version of wine. Dunno if that could make a difference or if it's basically the same as the other methods. I'm gathering you could run it like WINE_CPU_TOPOLOGY=4:0,1,2,3 %command% to only tell about 4 cores.

But i don't really understand really anything about it 😁

@Blisto91 THAT WORKS! Nice find!

So I can run
WINE_CPU_TOPOLOGY=31:0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30 %command%
and it will launch but if I do 32 then it will act as it would without the command.

Space Marine will run with
WINE_CPU_TOPOLOGY=26:0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25 %command%
but not 27. I'll post that over on that issue thread as well.

Symptoms:

• with no launch options, Ubisoft Connect starts, but the game does not launch

• vk_radv %command%: Same as with no launch options - Ubisoft Connect starts, but the game does not launch

• vk_amdvlk %command%: Launches but freezes immediately at the very first loading screen; it does not even reach the main menu:
  

• PROTON_USE_WINED3D=1 %command%: Game runs, but with massive graphic glitches, see video:

https://user-images.githubusercontent.com/18660100/177756123-4ca3d5a3-3dea-400f-a36f-06c666d16009.mp4

Changing between different ingame graphics settings does not have any effect on these glitches.

@ngreve It's likely a dxvk issue. I also reproduce a hang at the initial loading screen. Tho that is with radv.
I have made a issue about it here https://github.com/doitsujin/dxvk/issues/2669
And there is another issue from a windows user that the game crashes when they use dxvk.

Does it say anything interesting in the proton log when you try to launch with radv or amdvlk?

Edit: i am sorry i accidently pinged the wrong person first time

Running with vk_radv the last message says (steam-298110-radv.log):

5862.720:0150:0154:trace:seh:raise (22)
terminate called after throwing an instance of 'dxvk::DxvkError'
5862.720:0150:0154:fixme:msvcrt:__clean_type_info_names_internal (1000B488) stub

Running with vk_amdvlk i can't find anything interesting, but that's because I actually do not know what I am looking for (steam-298110-amdvlk.log).

This in your radv log is very odd.

info:  Required Vulkan extension VK_KHR_surface not supported

That should not happen as i'm pretty sure that is a pretty old supported extension (and required for anything to work). Could you try reinstalling radv and see if anything changes?
Be sure to install both 32bit and 64 bit version.

The requested system information (also updated my OP)

I've reinstalled vulkan-radeon and installed - the missing - 32bit version of it.
Now running with Proton-7.0-3 and vk_radv, the game freezes in the beginning just like with vk_amdvlk, but the message Required Vulkan extension VK_KHR_surface not supported disappeared, I guess that's progress (?).

But I also revisited ProtonDB and saw that people got the game running with Proton 6.3 in the past.
So, I've tested it with Proton 6.3-8 and I've got it running with with vk_radv and vk_amdvlk.

But I encountered another bug. At some point, if you switch between different Proton versions, an error message appeared that said something like "No Ubisoft Connect installed. Install it so run the game... (blabla)". This error occurred every time when I've switched from Proton 7.0 down to 6.3. Switching back to 7.0 did not fixed the error, I needed to reinstall the whole game.

So, to get it running with Proton 6.3, I firstly needed to uninstall the game.
With the game uninstalled, go into Properties -> Compatibility -> Select Proton 6.3-8, then install the game.
Now Steam/Proton finds Ubisoft Connect and starts the game.

Again, the game now runs with Proton 6.3-8 and both vk_radv and vk_amdvlk.

If they are using https://aur.archlinux.org/packages/amd-vulkan-prefixes i think as long as they launch with vk_radv %command% it should be fine. In the game at least. But yes the lines look odd in the system report.

@ngreve Good to hear with some progress. Could i get you to try and start the game 3-4 times into the main menu with 6.3-8 and see if it succeeds each time? at least my own issue was that it only happened some times. If it doesn't freeze with 6.3-8 at all thats a good data point to try and find a regression for when i test it again later.

I've entered the main menu multiple times now and played for ~5min and it seems to run fine with two little caveats:

• Before you enter the main menu, there is this splash screen with the FarCry 4 Logo and the message "Press any key". When I now press a key, the game focus gets lost and I have to alt+tab into the game again. But then I am in fact in the main menu and can play the game.

• The game freezes, as soon as I try to enter the steam community overlay with shift+tab steam-298110-steam-overlay-crash.log.

EDIT: Btw, thanks for the exchange of ideas and getting it running in the end.

Okay thanks for testing.

On the second point i think i remember seeing that too when i was testing Far Cry 2. When i brought up the steam overlay it froze. Forgot to make a comment about it.

But I encountered another bug. At some point, if you switch between different Proton versions, an error message appeared that said something like "No Ubisoft Connect installed. Install it so run the game... (blabla)". This error occurred every time when I've switched from Proton 7.0 down to 6.3. Switching back to 7.0 did not fixed the error, I needed to reinstall the whole game.

You just need to delete the compatdata folder for the game. You don't need to reinstall the entire game.

Replying to https://github.com/ValveSoftware/Proton/issues/2143#issuecomment-1148536945

Genius! Yes, I have 64 cores that will be it! Man that's quite the find.

@kisak-valve did you managed to get it working by any chance? Just got it on a sale and it's dead stuck for me and I'm also using RX 7900 XTX.

For the sake of the argument, I also did not give up on this, my hardware is still the same and I tried a couple of months ago again. It still won't boot.

It weird though, there are quite a few fairly recent report on ProtonDB that it works, both nVidia and AMD users, but well, tough luck then I guess

I mean.. yeah.. but if possible I would definitely like to play that one, it's the one that is missing out from my collection of Far Crys

I'll be honest the following did it for me

WINE_CPU_TOPOLOGY=31:0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30 %command%

I've been trying all of those yesterday with no luck. I'm using 5900X, so it's 12C/24T, I've also tried

WINE_CPU_TOPOLOGY=4:0,2,12,14 %command%

Still hangs at the loading screen:

@agurenko Assuming you're using proton stable, could you try using Proton 9 (currently in beta) and see if you still have the issue? You might need to delete the game's prefix.

@agurenko Assuming you're using proton stable, could you try using Proton 9 (currently in beta) and see if you still have the issue? You might need to delete the game's prefix.

I've tried all versions from 6 to 9, Experimental and GE both 8 and 9, so no dice

I can confirm that the game no-longer works using Steam Proton Experimental or 9.0.1.

Ubuntu 24.04 - Nvidia RTX 3080 - 535.171.04

Clicking the Play button should initially start the installation process for Ubisoft Connect, but this never happens, I see the processing Vulkan shaders and then it returns to the Play button again.

Native Steam package with the game installed on an Ext4 formatted partition.

OK, so I managed to get it working.

Install UbisoftConnectInstaller.exe as a non-steam game using Proton Experimental.

Then launch the game again, and it correctly will launch Ubisoft Connect and load the game.

You still need to disable the Steam Overlay however.

Thank you a lot @intelligentgaming, not only your solution fixed Far Cry 4 for me but also allowed me to solve another issue I had on Mass Effect LE! 🎉

I remember a week ago I used to play "Outpost Master" non stop because I could quickly reload the stage and assess my approaches, it was fun.
But then, I progressed further in the game. After making the Arena available and conquering the first fortress in the game, every-single-outpost now takes forever and then some to load. Quick reloads are gone, they take additional time, ruining the fun. I've tried Glorious Eggroll, Proton, Linux runtime, you name it but apparently this is something I can't workarond.

I guess you can't have too much fun with an Ubisoft game.

I had the same issue about the process just hanging at start (not even drawing a window).
I fixed it with sudo sysctl kernel.split_lock_mitigate=0. As soon as I ran that, the game just came to life.
