The game starts for a split second, and crashes. In the logs I see this last message:

wine: Call from 00006FFFFFFA3A58 to unimplemented function USER32.dll.GetDpiAwarenessContextForProcess, aborting

It seems it has something to do with HiDPI support in WINE.

EDIT:

Game works fine on my Arch Linux and SteamDeck when using this launch option:

SteamDeck=1 %command%

Replying to https://github.com/ValveSoftware/Proton/issues/8495#issuecomment-2697479701

Doesn't work for me personally. The game closes/crashes right after trying to launch it, with no window whatsoever showing. I can't even get Proton to write any log.

Try deleting the prefix and runing with the SteamDeck=1, I was able to run it that way

Nope, still doesn't work, same thing happens.

For me it launches with SteamDeck=1 %command%, without it Proton's wine probably needs https://gitlab.winehq.org/wine/wine/-/merge_requests/6802 to be merged
EDIT: Yep, applied the patch and compiled Proton manually, the game launches fine without any additional tinkering required. With SteamDeck=1 Online doesn't even load; without the environment variable and with the patch applied it loads but the player gets kicked after a few minutes due to BattlEye support not being enabled by Rockstar

Doesn't work here with or without the SteamDeck=1 launch option on Desktop.

The game didn't launch because the launcher stuck.

Proton ver: 1741023333 experimental-bleeding-edge-9.0-169490-20250303-p9fdc47-w507bc0-d9769df-v6c9103-unstripped
Proton log: steam-3240220.zip

When using Heroic Games Launcher, SteamDeck=1 environment variable didn't work for me, but adding -onSteamDeck as argument to executable did work. Online doesn't work, tho. At least Story Mode works now.

I was able to launch the game with SteamDeck=1, but sadly, unable to join an online game:

Tried the tinker from Legacy, but no success

Compatibility: GE-Proton-9-25
Command: SteamDeck=1 PROTON_BATTLEYE_RUNTIME=/path/to//SteamLibrary/steamapps/common/Proton\ BattlEye\ Runtime/ %command%

The game will automatically disable BattlEye if it's told it's running on Steam Deck. Wait for the Wine patch for it to come to Proton, but even then I don't know if it'll work.

I understand that Rockstar would add a few lines of code to automatically disable BattlEye on Steam Deck, but the fact they went a little further and made it skip that unimplemented function in the same context makes me question if they're softening up, like you might as well just leave it broken if you don't officially support it.

Yeah I realised that checking the invoked process. Tried with -onStemDeck arg so -nobattleye doesn't get auto added and I'm getting a "You've been kicked by battleye" error instead, upon joining

This is just speculation, but i don't think GTA Enhanced will work on linux if your sole goal is to play onlline, from what i know they added BattlEye/Kernel Level Anti-Cheat on GTAV, which makes it incompatible with linux. its most likely the same for GTA Enhanced sadly

Your best bets are to just dualboot windows when you want to play GTA Online, this is a big issue that happens with lots of games implementing kernel level anticheat such as Riot games

Thanks for your input. Unfortunately, I have taken the decision recently to entirely ditch my dual boot for ethical reasons. As part of this, I have also ditched games I used to play (Riot, and or Respawn), so I'm afraid if this is indeed the direction Rockstar is taking, I'm afraid it's going to be a pass.
Hopefully you are wrong :D
for now, I still have the story mode to do again

I am running it using SteamDeck=1 %command% and Proton Experimental Bleeding-Edge. Unfortunately, it hangs when trying to use Franklin's special ability on the starting section:

It hangs right when I press Caps Lock into that scene. I had to then kill the process. Here follows the proton log (zipped because it turned out to be enormous):

steam-3240220.zip

I've also tried running the game with the -safemode command-line parameter but it locks up the same way.

Also, running the game at all does not always succeed. Sometimes I just get this message:

My system information (Ryzen 7 7800X3D, Radeon RX 7900 XTX, Archlinux): https://gist.github.com/Patola/ecc08624307296709b35756a5cb246d8

The game should now launch without any additional tinkering required on Proton Experimental bleeding-edge branch, because commit https://github.com/ValveSoftware/Proton/commit/256e9783cc07d216532fbe90a45321a80699ddc3 (updates wine to commit https://github.com/ValveSoftware/wine/commit/50dbb59157f4344dec3eceafa6aceafb5dda0592) adds the missing syscall (which in turn has been implemented in https://github.com/ValveSoftware/wine/commit/7b31aae6200640391682db757962b9b5120a2b30) that is required by the game.

Does this also fix the hang on activating Franklin's special ability? (I will test of course)

It didn't. The hang still happens.
Doesn't seem to be related to the graphics because there's no amdgpu alarm on dmesg and the hang also occured in -safemode. But I'll try running it also on my NVIDIA laptop to be sure.

Running grep vkd3d-proton on your logs does show quite a bit of warnings, these might be of interest:

Thanks, @Exotic0015. Weirdly enough, yes, it works in my NVIDIA laptop with this configuration. Not sure what I should do though. These errors also appear on the proton logs for the VR game Metro Awakening, but it runs nevertheless. Should I try and use a different kernel?

Wouldn't hurt to try; try running the game on the stock kernel and report back if it fixed the issue.

proton hotfix has been fixed

The game no longer works. Verifying files, deleting compat folder, changing Proton versions etc does nothing.

Can confirm, I am also encountering the error above on Proton Experimental bleeding-edge
Logs suggest an access violation in D3D12.DLL and d3d12core.dll, so I'm guessing one of the recent commits in vkd3d-proton is causing this.
Edit: Reverting vkd3d-proton back to https://github.com/HansKristian-Work/vkd3d-proton/commit/078f07f588c849c52fa21c8cfdd1c201465b1932 (since that is the last commit I've tested the game with before the breakage) made the game launch without any problems.

Take note that the game is still working on NVIDIA GPUs with Proton Experimental bleeding-edge. It's not working on AMD GPUs though, so there's some interaction between vkd3d-proton and the GPU driver that prevents it from running.

Where you got this information?

The game works just fine here on AMD GPU (RX6900, proton-experimental).

I don't know what changed, I have tested about 6 hours ago, using my desktop with an RX 7900 XTX on Archlinux with mesa 25.0.1 and I've asked two other friends in chat that have AMDs (7900 XT and 7800 XT), one with Fedora and the other one with Archlinux. We couldn't make it run, it was just showing that "Unable to launch game, please try reinstalling the game".

And for working in NVIDIA, I have a practically identical setup in my laptop but with an NVIDIA RTX 3070.

However now I have just tried to run it again in Proton Experimental bleeding edge and it worked.

UPDATE: just after that, tried starting the game 5 more times and it keeps waiting in the animated "R" window.

UPDATE 2: it still hangs when I press "caps lock" to call Franklin's special ability, but that's on me, still using the same kernel.

Confused as to why this game was marked as playable on deck, the original version is still marked as unsupported cause of anticheat and i dont believe anything has changed with this

@waspennator the singleplayer mode is playable using SteamDeck=1 %command% in the launch options to disable the anticheat, but the online version is not because it requires BattlEye's kernel level anticheat

yeah but why did valve change the status to supported tho.

I agree, the online mode is a major part of the game. As long as it does not work in addition to single player, this should not be marked as supported.

The new Playable rating is clearly wrong and has affected Rainbow Six Siege too https://github.com/ValveSoftware/Proton/issues/946

It was previously rated Unsupported on the now Legacy edition for the same reason of online being blocked intentionally by Rockstar. There's no way Playable is correct for this.

Seems like it was a mistake, both games are unsupported again.

Wouldn't hurt to try; try running the game on the stock kernel and report back if it fixed the issue.

Did just that and the hang happens on kernel 6.12.19-1-lts from Arch pretty much the same way it does in my 6.13.7-273-tkg-eevdf. Using mesa 25.0.2 now

@waspennator the singleplayer mode is playable using SteamDeck=1 %command% in the launch options to disable the anticheat, but the online version is not because it requires BattlEye's kernel level anticheat

You can use FSL to bypass anti-cheat and play online mode with BE turned off

I would also like to play Arch Linux in online mode, but this crap doesn't work

I set a Proton Experimental with SteamDeck=1 command
If set language to English its stacks on launcher
But if set another language, its loads nearly perfect, even a GTA Online works...
But with 1 excuse - within 5 seconds after you fully connect on session (or momentally) it raise an error like on pic

Thats means that with this time BattleEye is working, also as a GTA V, BUT BAttleEye blocks online instead

Some correction - without forcing compability in steam it goes to same result

Grand Theft Auto V: Enhanced (3240220) - Moving Camera with RT Lowers Framerate

Issue transferred from [#8606](https://github.com/ValveSoftware/Proton/issues/8606). @Crozh posted on 2025-04-13T21:29:25:

[...]

1)Open GTA V. 2)Enable an RT setting of any kind, AFAIK the every setting has the same issue. 3)Move the camera around, wheter on foot or in a vehicle. 4)Framerate should lower dramaticaly, the speed in which you move the camera matters.

In regards to the stuttering, I have determined it to be related to the steam overlay. If you add LD_PRELOAD="" to the start of the launch options, like LD_PRELOAD="" %command%, the issue never appears.

Freezing while in Ammunition

Whenever I am in ammunition, and I have bought a gun or an attachment to the gun and I hit "back", the game freezes every time. The sound keeps playing until the track is "done" and stays frozen visually, and does not respond to any input. The issue has also appeared once in the middle of a mission, but that has not happened since.

Running steam in my console I can see this error popping up when this happens:

err:winevulkan:signaller_worker error waiting for semaphores, vr -4.

I need to kill the process to close the game.

Hello Valve or whoever reads this, I am a linux user and I just want to say that I love playing there but it is a shame that companies like Rockstar Games,EA, Ubisoft suddenly update their anti-cheat and stop supporting linux users, before Grand theft auto v worked perfectly but since last year they updated the anti-cheat to battleye we can no longer play, This kind of things should not be allowed and something should be done about it, if not I wish they could put a solution or contact this kind of companies, in this case Rockstar Games, I'm very pissed off, thanks for reading me.

Hi @rcv11x and anyone else reading this,

I highly doubt anyone at Rockstar follows this forum. If you want you can give feedback to Rockstar you can do so via https://www.rockstargames.com/gta-online/feedback - and perhaps there's a slim chance they will chance their stance at some point in the future, or maybe take this into account in future games.

I suppose this forum is better kept on point on what Proton can do. GTA Online and other games with windows-only BattlEye version is out of the scope of Proton.

Replying to https://github.com/ValveSoftware/Proton/issues/8495#issuecomment-3005490666

I can confirm this being an issue, but this extends to all cutscenes as well.
It only seem to happen with a certain level of high quality settings too, so I am not sure what specifically affects it. Have you had a chance to play around with post processing and blur (depth of field) settings?

Replying to https://github.com/ValveSoftware/Proton/issues/8495#issuecomment-2994426665

I'm sure I've used LD_PRELOAD in GTA V, I use it in almost every game. Still have PTSD with the overlay crashing, bugging or lagging any game it hooks on to - I can't recommend the command enough.

Has anyone had an issue with audio where some sounds mostly come from the left audio channel, e.g. vehicles, npcs and other environmental sounds

Got a major bug to report. Regardless of which Proton version is used (9/10/Experimental), all input going to the game completely shuts down the moment I switch to a mouse-based window like Google Chrome or Discord, rendering the game totally unplayable unless you force-close and restart.

Has anyone had an issue with audio where some sounds mostly come from the left audio channel, e.g. vehicles, npcs and other environmental sounds

Yes, I'm having this issue. Tried new ProtonGE ALSA sound tricks but they didn't change anything for me.

When i play in first person all sounds from behind go to left ear. Can be noticed easily when standing next to road or train tracks and right ear is facing to road or rails. When rain arrives from ahead sound comes correctly from right but soon as it goes behind player sound moves to left.

with -disableSpatialAudioClient flag Menu sounds move to left with many other sounds too but stereo mixin in FirstPerson camera works as intended in previous scenario.

I've been playing Rockstar Launcher version with Lutris launcher and tried many proton versions and variants. It feels like no matter what you do stereo sounds(mixing) are someway broken. I don't have similar issues with Win11.
