This game will need this bug to be fixed in LLVM 7 in order to run on the RADV driver.

https://llvm.org/viewvc/llvm-project?view=revision&revision=340171 Fixed upstream and patcher says it is being backported to LLVM7

seems to play perfectly here too with one caveat - when I start the game there is a message saying it was unable to reach the game's servers. probably same issue as #162

Ubuntu 16.04, NVIDIA GTX 970, Proton 3.7-5 Beta:

Steam System Information

^ Unable to connect to online servers
^^ Default graphics preset is High

NOTE: Frequent screen tearing if Vsync setting is Disabled

How are you guys launching the game?
I can't get the game to launch as it can't make connection with the servers.

It complains that "the server is not reachable, check your internet connection". If I try launching the game with Steam in offline mode (or by unplugging my ethernet) as a way to potentially work around this, it states that "Steam is currently in offline mode, for the first launch go in online mode".

Tried with both 3.7-3 and 3.7-6 to the same result.

@DougTy - I started the game with default Proton and it just ran. Didn't do anything special on top of that. I did get a network error in the game menu, but I assume this only affects the online components of the game. I was able to spawn and run around in my base (although I didn't try starting a new game)

Nope, not working on Debian. Characters are completely messed up.

Tested on Debian Stretch AMD64 / 390.77 / KDE with locale FR.

Reborn OS (Arch Linux)
AMD FX, Nvidia Geforce GTX 950 v.396.54-1
Proton Beta 3.7-4/5/6

When I start the game there is a message saying it was unable to reach the game's servers.

When they're available on Debian I will.

I am also having a connection issue, Manjaro Linux.

Any workaround or fix?

I am also also having a connection issue on solus linux.

Any workaround or fix?

steam system information: https://hasteb.in/ewapoqal.yaml

double-checked if anything had changed since my last report since so many people have trouble starting the game, but the game loads fine on my end still (tried with 3.7-6 this time, no difference). I still get the popup at the beginning saying I won't be able to use online features, but I can play the singleplayer game fine.

same sysinfo as before

What do you click when you get the popup?

I get "Retry" or "next".

Retry just makes the pop-up loop over and over and 'next' leads me to a link which isn't overly helpful because there is nowhere for me to paste the code?

(Also, I am using 3.7-6 BETA at this time also, thanks!).

I'd like to add a quick edit that the link provided above is of no use to me (or @DougTy because it is for a different issue altogether).

The game isn't working for me. It crashes before showing any window.
Starting it from the command line shows some info, just like @NaltanHusky's post in #1131.

My specs are:

Antergos (Arch Linux) Kernel 4.18.7
Intel i5 4690k, AMD R9 290X
Mesa 18.3.0-devel

@tunanachos I don't think we're talking about the same popup - I think you're getting the outside-of-game popup that complains about not being able to reach some server, my game starts fine, but then from within the game it warns that I won't have access to the online features (there's no choice after that except to acknowledge it and continue)

@Cuddlypuff No I don't think we are, I'm aware MGO isn't really viable but that isn't my issue.

Me and @DougTy cannot launch the game at all, instead (assuming he has the same issue as me) you get a pop-up stating that it cannot connect to servers (I assume DRM?).

Is it worth me making a post about this somewhere other than what I've done here? Seems like I am not the only one facing this issue (not to mention it's a bit annoying MGS:V plays so well with Linux+Proton but the DRM is stopping us), forgive my question - I don't often use Github etc, confuses me lol :)

@tunanachos I think @kisak-valve has been merging issues of the same game under the same report, unless they're officially supported games then they track all separate issues independently.

Did you ever start the game on any other platform? I had started the game using Lutris previously, and my Proton session is able to find that cloud save and run from there, so maybe that's where our experience differs?

Just brainstorming here: For those who have it working, had you launched the game at least once on Windows before? Maybe it does some sort of setup the first time you start it, which doesn't work on Linux.

Gave me a warning about inaccessible online mode, but apart from that it works just fine for me on Ubuntu 18.04 with Proton 3.7.6. I had played it on Windows first though, hence my question.

@DanMan not on windows, but I had started the game previously though Lutris without issues (no idea what versions of wine/dxvk i wouldve been on)

@Cuddlypuff Thanks for the reply

I had a go at installing it with Lutris but that was even more-so uneventful (forgive me, I fail to remember what happened but the abridged version is, it didn't work) .

I can reinstall it and maybe try running it in a console and see what the issue is, but as far as I can tell, it's just bypassing/connecting the DRM to the server which is my main issue (Running it purely with Steam+Proton).

I wonder if it has anything to do with my WM? I use i3wm and sometimes I feels as if games don't like it.?

@DanMan I don't think this is the case, I may be wrong but unless you mean a VM Linux and Windows would be installed in entirely different locations, with different paths - most likely both OS's wouldn't hop over and check the other, if that makes sense? (happy to be wrong on this).

Just brainstorming here: For those who have it working, had you launched the game at least once on Windows before? Maybe it does some sort of setup the first time you start it, which doesn't work on Linux.

I've played through the game on windows already. but I reinstalled it for linux. It won't get past downloading Microsoft redistributable

According to [a comment in #162](https://github.com/ValveSoftware/Proton/issues/162#issuecomment-421111573), Proton is based off of wine 3.7 & a large network issue was fixed in 3.9. Perhaps when @Cuddlypuff ran the game first in Lutris with system native wine >3.7, it activated the game's DRM there, so that pre-launch popup doesn't come up anymore when running the game in Proton because it's already activated.

I've actually tried the game with wine-staging 3.15 and it plays fine, no such issue, so I'm thinking this is just a case of Proton being based on too old a version of wine.

Hi @DougTy are you now able to play MGS:V without issue now? How did you go about setting it up? Just a usual Wine directory? No extra libs or anything?

I can happily redownload it and give it another go, especially if one of the only other people I've found with the same issue as me has now got it working.

@tunanachos Kinda. It works decently well with wine-staging 3.15 & DXVK 0.71. Lighting is a bit weird but the game launches & plays fine, however it seems to constantly corrupt my saves. I'll play the game without issue for however long I want, but upon launching the game a second time it claims my saves are corrupted and forces me to start from the beginning again. I haven't really put too much effort into debugging this so perhaps someone could get it to work -- though this isn't a Proton issue and should probably be taken up on AppDB instead.

There is no network error with wine-staging, but I definitely can't get the game to run in Proton still, even when using the game's compatdata folder as my WINEPREFIX with wine-staging first. Proton always claims that I have no internet connection. I believe Proton will need to be rebased to a newer version of wine in order to fix this.

Mmm, I might give it a couple of months and see if any progress has been made. I'd rather run it through Proton for simplicity sake and this save-game issue is off-putting to say the least (I have a bunch of Windows games I'm working through at the moment that work great with Proton, so I'm not lost for time killers).

I don't know whats worse; being able to play but not save or not being able to play at all...

Guess you could just tab out and leave your PC on forever until you're ready to quit lol.

Thanks for the reply, I'll see whats happening around Christmas if there isn't much of an update.

-Cheers

I've got the same error on Arch Linux when I started it with steam-native but it works with steam-runtime. I still get the ingame warning about the failed connection tho.

@DougTy Same issue with me. It loads and plays perfectly, aside from the servers not resolving, but after extended periods of play the game starts corrupting my saves. I started backing up my files after every session and stepped through the missions. Your results may vary, but after mission 6 "Where Do the Bees Sleep" it seemed to start corrupting my saves.

From what I've read online, there seems to be a rich history of this game corrupting saves due to the game state in relation to the companions. All the complaints seemed to peter out after 2015, so my guess is the devs fixed those issues. Running it through proton might have revealed a few more.

4.18.10-arch1-1-ARCH
AMD Ryzen 5 2600 (12) @ 3.400GHz
NVIDIA GeForce GTX 1070 Ti

Seems to run just fine with NVIDIA GeForce GTX 1050Ti, but after several hours of gameplay some sound issues show up, like crackling and echo, this is also happening with a few other titles like Outlast 2 and Dark Souls Remastered, strangely enough this issues appears after several consecutive hours of gameplay and is remedied by restarting the game. All system sounds are perfectly fine and no linux-native games have this issue.

Sounds like exactly the reason why you'd either want to install xact via winetricks, or wait for FAudio.

for those who have problems: give the game a first launch in "steam runtime" mode! after that it should be able to run also in "native steam" ;) your welcome

but i get also the message that i am not be able to connect to servers for some online features....singlplayer just runs perfect though...
any solution on that?

Game starts fine for me, gamepad works and performance is great. However, online mode doesn't work at all, whenever you start the game it tells you it can't connect to the servers. Also whenever I change the graphics options, the whole screen starts to flicker like crazy and I have to restart the game. The settings will be accepted and the game runs fine after restarting, though.

I can't play because menu elements are in the wrong position and most text is upside down. Also up/down in menus are inverted.

On ProtonDB, some other users have the same issue and one of them said this happened after they installed SteamVR and they fixed it by completely reinstalling steam. Unfortunately I have a very slow internet connection so I can't really reinstall everything or remove SteamVR since I use it and it's quite heavy.

Is there some trick to maybe hide SteamVR integration to the game or replicate the environment in which there is no SteamVR somehow?

Or even 415.xx would probably do!

Here is my system information @kisak-valve : https://gist.github.com/fazo96/03943c8a666b5ae529db6adbbf846cee

Not sure if it helps to know but other Proton games run just fine, even the ones requiring transform feedback such as GORN on SteamVR.

steam-287700.log

This is the log file, at the end I force closed the game because I did not want to sit through the unskippable cinematic at the start for the milionth time. The bug is noteceable almost immediately after starting the game due to some unreadable dialogs rendering. Also I tried disabling the steam overlay and nothing changed

steam-287700.log

Here's the new log with the intel files removed. I also tried disabling the steam overlay.

It did not work and the issue is still there. I don't think any game is rendering with the Intel graphics because I play at 2540x1440 and get good performance with high settings in other proton games.

@kisak-valve I tried something else: I installed the game using Lutris, so it runs on Wine + DVXK using Steam for Windows inside wine (proton/steam play not used at all)

The game runs perfectly.

Wine version: tkg-3.19-x86_64 (installed using Lutris)
DXVK version: 0.91
Everything else is the same as before except I updated my drivers to the latest Vulkan Beta, version 415.18.04

Running the game in Proton though Steam for Linux still has the same distorted graphics as before.
Running the game in Wine through Lutris works perfectly.

I think this makes the problem specific to Proton. If I have time, I'll try uninstalling SteamVR from Proton which according to another user fixes the problem with this game.

@kisak-valve I can confirm uninstalling SteamVR fixes my problem, the game on Proton now runs just as well as DXVK + Wine, however only if SteamVR is not installed.

Maybe this could be fixed by a flag that hides SteamVR to the game? The game has no VR elements that I know of.

I can also confirm that uninstalling SteamVR fixes the rendering issues with upside-down text and the game runs fine now. Though I don't understand how that could be related.

With Proton 3.16-6 the online mode works now without any problem. The screen flicker after changing the graphics option is also gone. With that all remaining issues are fixed for me now.

Sysinfo: https://gist.github.com/NoXPhasma/4273d8bfe7dc611fb74967ea44936989
Proton: 3.16-6

With Proton 3.16-6 the online mode works, the glitches when changing graphics options are fixed, and the glitches when SteamVR is installed are gone as well!

While online works now that is only one issue, using a mouse and keyboard is still impossible. I got to have a controller plugged in or the camera pans out of control, and the mouse won't navigate the map.

This stems from a windows bug that is "exacerbated" under wine: https://steamcommunity.com/app/287700/discussions/0/527274088389275023/

Can anyone can figure out a solution to this?

I can also confirm that uninstalling SteamVR fixes the rendering issues with upside-down text and the game runs fine now.

Agreed, the application now appears to be working as expected with Proton 3.16-6 once SteamVR is uninstalled:

Steam System Information

One problem I have is with the Steam overlay. If you bring it up, the same XB1 gamepad input is also still registered in the game. Especially evil on the title screen where you can delete your progress by activating a single menu item.

@DanMan Is this really a Proton specific behavior or does that happen on Windows as well? I've never palyed this game on Windows, so I have no idea. But for what I can say about other games, if the game pauses on Windows in Steam Overlay, it does the same with Proton for me.

Hi,
The same phenomenon (reversed chars, unplayable game, and so on) also appears w/ NVidia 410.93 driver.

Still upside down characters with Proton 4.2.2 and Buster and NVidia 410.93. (LOCALE is French, running on KDE)

Any idea ?

• Playing with linux mint (it worked out of the box there);

Fixed the error by reinstalling various libraries, ended up being an issue with a bad install of DXVK.

And would you care to explain how exactly you did that?

And would you care to explain how exactly you did that?

The built-in DXVK library as part of nVidia 430 was insufficient for this game specifically, despite working with many other DXVK-requiring titles. Instead, I followed the guide on this site and used the debian packages. Once those were installed everything worked great.

Yes, thank you. It seems that for me on the newest Manjaro KDE release (manjaro-kde-18.0.4-stable-x86_64) it works out of the box. It seems that Proton has issues running games from NTFS drives and moving the game to my ext4 SSD main drive and it runs perfectly out of the box.

If SteamVR is installed, the game is completely borked.- Without SteamVR all is fine.

EDIT: This issue now appears to be resolved with Proton 4.11-11, many thanks to all involved!

This issue still exists, with general text and menu options appearing upside-down when SteamVR is installed, as reported by @jaubin and others:

Anybody else having issues launching the game with 4.11-8?

Compatibility Report

System Information

• Kernel version: 5.2.21-1
• Link to full system information report as Gist: Gist

Symptoms

When launching the game, a window of the game appears with the 3 loading dots at the top right. These dots do not move, and the screen is then frozen. Tried this multiple times with the same result. To get it working I had to run MGS5 with Proton version 4.2-9.

Reproduction

Launch game.

The WINEDLLOVERRIDES workaround should no longer be required with Proton 4.11-10.

Proton 4.11-11, having mouse issues with a graphics tablet connected (Huion instead of Wacom, but maybe related to #3162?). Launching the game with a tablet connected results in both camera and map cursor moving left and upwards. Unplugging the tablet fixes the camera, but not the map cursor. Launching without a tablet connected causes no issues.
Logfile with a tablet connected:

System information:

I get constant network problems and frequent disconnects. Using 4.11-12.

For me the colors are extremely washed out in this game. Its runs with very good performance, but the colors are completely off.

Arch Linux with Nvidia 440.44 on an Optimus Laptop and Proton 4.11-12.

With 5.0-3, there is still a problem with the network.

I think this line is the most telling.

11420.060:0030:0065:err:winediag:SECUR32_initNTLMSP ntlm_auth was not found or is outdated. Make sure that ntlm_auth >= 3.0.25 is in your path. Usually, you can find it in the winbind package of your distribution.

And then all the following.

11420.981:0030:0065:fixme:winhttp:set_cookies unhandled attribute L"HttpOnly"

@sakuramboo, I doubt any of these have to do with the constant network issues. NTLM is the protocol to authenticate Windows machines in a local network (file shares), while HttpOnly refers to a feature of cookies that tell a navigator not to accidentally send cookies over HTTP too.

i change the save path of the game check the video and it's works with me

Looking into it, and trying a few things i cant seem to get it to work on the zen kernel. I'll give it a shot on a stock kernel
EDIT: Looking into, it looks like an architecture mismatch (32/64bit) I'll see if its a library problem
Edit2: Interestingly, lowering the proton version to 5.10 has seemed to fix the issue. Included below is the output from 5.10
steam-287700.log

@kisak-valve
I lowered the version to 5.13 and it works but it definitely doesn't work with 6.3; looks like a regression :/

@kisak-valve Sorry for being late to respond
I've already progressed passed this point and the game only permits for one save file; do you know if there's something I can do to work around this to get back to you on the log and other data?

You can get savegames for many levels here: https://steamcommunity.com/sharedfiles/filedetails/?id=523041722 but

pirated copies are known for some gamecrash problem with the first mission

Just sayin'. The game might actually try to detect pirated copies and running it through certain Proton versions might cause a false positive.

I've had savegame corruption issues before, like I said further up. But currently it works fine with 6.10-GE-1 for me.

Might want to try the 6.3-5 RC, because MGS5 is listed among the improved games. I think there's a video cutscene right after the mission that was mentioned

Hi,

There are also some savegame corruption issues in the game after a very
specific mission if you do some specific action. Forgot which one :

https://www.polygon.com/2015/9/8/9276195/metal-gear-solid-5-corrupt-gamesave-bug#:~:text=Konami is warning players of,saves and makes them unusable.&text=Doing so can trigger the,it out in the future.

That particular bug was supposedly fixed a long time ago though: https://www.rockpapershotgun.com/metal-gear-solid-v-quiet-bug

For me it happened a lot earlier in the game at 2 different times.

The games still plays the cutscene in Phantom Limbs at 2 or so fps. Same with the chapter 2 trailer, only time I've noticed it.

I was revisiting this yesterday, playing on Proton 7.0-4, and I noticed the FMV cutscenes play back at double speed and audio pitch, which, albeit hilarious, is kind of a problem. It's also annoying to reproduce, because the first FMV is after the initial 20+ minute long hospital escape sequence. I switched to GE 7-31, I'll just keep playing and hope I encounter another FMV to test.

Update: Tested some other Proton versions.
In Proton 5.13, the cutscene is skipped, pretty seamlessly. Someone who didn't know better wouldn't notice the cutscene was missing...

In Proton 6.3, the cutscene renders slowly at ~1FPS
In Proton 7.0 and onward (including Experimental bleeding edge and GE), the cutscene plays at 60 FPS (double speed.)

steam-287700.log (from Proton Experimental bleeding-edge)

Here's a save file if any developers would like to reproduce the issue faster.
It's in a .tar.gz with three files, since I don't actually know which one of them is the save itself vs. the character avatar data, etc.
This should be placed in $STEAM/userdata/bunchofnumbers/311340/remote
Then simply hit Continue at the main menu and skip the first two in-engine cutscenes. Then the mfplat video will play.

Still affected in Proton 8.0-2. 😐

Interestingly, at the current GE the prerendered cinematic intro to Chapter 1 just got skipped entirely after showing the first frame for about half a second

Using proton 8.0 or experimental:

After a while of playing, there starts to be a micro stuttering every a random number of seconds (every more than 30 seconds)

I remember playing from start to finish, guess something broke in the last proton versions , tried proton 9.0, experimental and proton-ge.

Anyone know a way to continue to play the game?

stutter

Same here. Did you fix this?

Nope, I was able to progress by using Proton 8, but the cutscene doesn´t work, there was another cutscene after rescuing Miller that plays at double the speed and the voice is very distorced, kinda like robot type.

I think the game used to work with <workaround removed by moderator> / Media Foundation installation but for some reason now it doesn´t work, tried a bunch of combinations. It really seems missing a codec or something to render properly just don´t know how to install it and have it working like the old days.

Seconding this issue.

Replying to [#124 (comment)](https://github.com/ValveSoftware/Proton/issues/124#issuecomment-2241778216)

Why are only certain Linux users missing this video codec? Apparently only some are missing it because the game has great rating on ProtonDB.

There are hundreds if not thousands of different Linux distributions, and the game is nearly a decade old at this point, and does not receive regular updates. Switching to an older version of Proton (ie Proton 8.0) as mentioned above may fix the issue.

Using Steam Flatpak 1.0.0.83 (Steam Stable 1751405894) on Aurora (KDE spin of Universal Blue, based on Fedora Silverblue) I can confirm that switching chapters crashes on proton experimental and hotfix. Downgrading to Proton 9.0 in Steam's 'force compatibility tool' fixes the issue for me.

@kisak-valve to contribute here is the gist with the requested information:

While this may be a separate issue without its own report I noticed launching the game is significantly delayed taking 5 minutes or more to launch without error or indication that the game is open. This delay however is mitigated partially by disabling split_lock_detection via the kernel cmdline or split_lock_mitigation via sysctl. This reduces the delay to about 1 minute.

Thanks @slashmach1 , I don't know of an easy way to trigger one of the problematic cutscenes without deleting my save and re-playing through the (long) prologue. How did you test?

@dryya im using fedora with btrfs snapshots pre and post game. disabling cloud saves when testing only

Same here.
I'm not sure it's related to Proton, as this delay occurs with the few versions I tested (8.0-5, 9.0-3, 9.0-4; Proton-GE), some (9.0-X) reported as working fine on protondb.
Thanks for your fix... I'll gladly provide any log or do tests if it helps solving this.

I'm having the same problem as @hakobi0 with a Radeon RX 6700XT with mesa 1:25.2.4-1 and linux-firmware-amdgpu 20250917-1 (both are the latest on Arch Linux). Game used to work fine

MGS V stopped launching on Steam Deck after the June 9, 2026 Steam update.

AppID: 287700
Depot: 287701
New manifest: 8183974873990090295
Previous manifest: 2518831260221836800
BuildID observed in Steam logs: 23407568

Error:
"Failed to load SteamAPI"

The game was working before this update. Depot 287701 had no public manifest updates since March 23, 2021, so this looks like a regression from the June 9, 2026 update.

Tested and failing:

• Proton 10.0-4
• Proton 9.0-4
• Proton 8.0
• Proton Experimental
• Proton Hotfix
• verified game files
• verified Steam Linux Runtime / Steamworks Common Redistributables
• deleted compatdata and shadercache
• tested steam_appid.txt with 287700

Workaround:

• Proton 7.0-6 launches the game successfully (Other Linux / Steam Deck users are reporting the same issue in Steam Discussions).
