Hi, I’m having serious stability issues with Cyberpunk 2077 on Linux and I’m running out of ideas and need help! I'm experiencing consistent crashes/freezes. The game always launches, runs smoothly, but no Proton version is stable. Crashes happen randomly during gameplay, often after 2-30 minutes. Usually after like 5 minutes. Running the game with PROTON_LOG=1 produces the exact same error in every proton version.

Proton versions tested:

• Proton-CachyOS 10.0-20251126 (steam linux runtime):
• Proton Experimental
• GE-Proton10-27: game ran the longest (~1 h), but crash here soft-locked the system (could alt+tab but nothing would launch, not even a terminal window), requiring a hard reset. Previous Protons allowed killing the process normally.

Proton GE:

err:virtual:virtual_setup_exception nested exception on signal stack addr 0x7f3a518b2e60 stack 0x7ffcce50

Proton Experimental:

err:virtual:virtual_setup_exception nested exception on signal stack addr 0x7ff6178b2e60 stack 0x7ffcce50

Notably, the address is always identical, suggesting a deterministic memory allocation issue.

Specs:
Kernel: Linux 6.18.2-3-cachyos
KDE Plasma 6.5.4
WM: KWin (Wayland)
CPU: AMD Ryzen 5 7500F (12) @ 5.08 GHz
GPU: AMD Radeon RX 9060 XT 16GB [Discrete]
RAM: 32GB

Happens in:

• Missions (e.g. Heist, Braindance)
• Menus (skills/perks)
• Sometimes after only 2–5 minutes, sometimes works up to ~1h if little happens on-screen

Things that I've already tested (all with cache clean + verify files):

• Ray Tracing OFF / ON
• FSR 3 / 4
• With / without gamescope
• With / without mangohud
• FPS limit only in-game (monitor 200 Hz)
• vm.max_map_count increased to 2147483642

Crashes occur in all configurations. Flags seem irrelevant. Ray Tracing may speed up the crash.

Game is opened through Steam, Launch commands tested:

Raw:

%command% --launcher-skip --intro-skip

Gamescope:

mangohud DXVK_ASYNC=1 VKD3D_ASYNC=1 PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 \

PROTON_FSR4_UPGRADE=1 PROTON_ADD_CONFIG=fsr4rdna4 \

WINEDLLOVERRIDES="winmm,version=n,b" RADV_PERFTEST=nggc \

gamescope -f -w 2560 -h 1440 -r 200 --force-grab-cursor -- \

%command% --launcher-skip --intro-skip -skipStartScreen

Without gamescope (last crash on proton GE):

VKD3D_CONFIG=no_upload_hvv PROTON_ENABLE_WAYLAND=1 PROTON_FSR4_UPGRADE=1 \

PROTON_LOG=1 PROTON_ADD_CONFIG=fsr4rdna4 mangohud \

%command% --launcher-skip --intro-skip

Last 100 lines of the PROTON LOG:
Proton LOG

I'm following this guide

https://www.youtube.com/watch?v=YNvfgYSmwwc

But reshade doesn't show up.

I tried putting a PS2 controller in the game, but it doesn't seem to recognize it. But on steam's big picture, it can recognize the controller.

I'm on popOS, i have an asus a15 (nvidia 4060), don't know if its relevant.
i've tried proton experimental, hotfix, 8-0-5 and 7-0-6. i made sure to have Easy anti cheat installed and chatgpt suggested to "disable" ipv6 or something like that.
Still cant connect, anything i'm missing? I'm not a linux expert, i've been using it for less than a month and i dont have very good knowledge in terms of "internet" and "network" stuff tbh, so i don't really know what could be the problem.

(everytime it gives the same error: C-00001-00898-1)

i also pased this into the lauch options:

PROTON_EAC_RUNTIME=1 %command% HOST_LC_ALL=$(echo $LANG) %command%

A little holiday update for Proton Experimental from Valve to improve Windows games on Linux, Steam Deck / SteamOS systems.

Installed Rust today as I used to play it on windows all the time, tried to get into a server and was met with a no EAC detected error.

noticed that Rust had installed via proton, and so the EAC installed was an .exe

Wanted to make a thread in case older threads had outdated info.

Is there any ways around this issue or am I going to have a Christmas without Rust?

Cheers.

Hello,

I am currently using Fedora 43 Cosmic. I have Steam installed via Flatpak because I don't see a system installation.

The problem is that I can't record gameplay. It seems to save a temporary file with the recording, etc., but when I try to play it back or save it, I always get an error saying that it can't be done.

Does this feature even work on Linux?

Does anyone know how to fix this?

Could it be a problem with my distribution?

I should mention that I switched to Linux from Windows about a year ago, so I'm still learning the ropes.

I installed and played "The Farmer was replaced" from Steam yesterday. No issues, everything worked OOTB.

Now, the next day, I only get this screen:

https://preview.redd.it/w6u2p8i4d59g1.png?width=1918&format=png&auto=webp&s=3017c9ec820dcdcc79cd58212d9d7674b3f74458

I can hear the games music, and it reacts to me pressing "ESC" (the screen gets a little darker).

I tried every common tinker steps:
Proton Experimental, Proton-GE, Proton Latest Stable, Launch options mentioned on ProtonDB: https://www.protondb.com/app/2060160

I'm running out of ideas here :(

I can connect it wirelessly through Bluetooth, but Steam doesn't recognize it, and it doesn't work in any games. It works without problem if I use a cable though. Everything worked fine when I used it on Windows before.

hi guys

I recently made the switch from Windows to Fedora. So far all the games I tried have worked, except for Anno 117.

When I press Play, it says "Running" but nothing happens. I tried using GE Proton 10.26 and 10.27 and adding the startup parameters suggested here: https://www.protondb.com/app/3274580

But nothing seems to do the trick. Are there any other suggestions by any chance?

Cheers and happy holidays!

Hi, I got a new monitor (1440p) and since then, Ive been getting heavy stuttering on games like cyberpunk (video), final fantasy rebirth and Warframe. I'd appreciate any help/advice in solving this!

I tried running it on windows and the stuttering doesn't happen at all, silky smooth.

Specs:

CPU: Ryzen 7 5800XT

GPU: Radeon RX 9070 XT ASRock Taichi

RAM: 32GB 3600 MT/s

1440p 180Hz monitor Freesync

I've recently started using Zorin OS after what microsoft did to us with Windows 10 and Windows 11, so I'm a total noob in everything with Linux

Here's the problem: Sometimes I need to use other apps while gaming (browser to switch music, OBS to record something, etc.), so I press alt+tab to switch to other apps. But when I switch back to a game, it completely freezes, I cannot close it, and I had to restart my laptop. Is there a way to fix it?

My specs: OS: Zorin OS 18 Core CPU: AMD Ryzen 7 260 GPU: Nvidia RTX 5070 8 GB SSD: 1 TB RAM: 32 GB

I have this particular problem with Warframe. Never tested on other game, but it still bothers me

If any other information is required, I'll be gla to provide it

so i tried playing ghost recon breakpoint via steam. I managed to get uplay up and running, but as soon as I picked my style of playthough, my linux os closed it, citing that it used too much ram. I have tried looking around for a solution but no one seems to have one. I have enough ram according to the recomended specs on the steam page, so why is it over using ram?

System specs:

OS: Ubuntu 25.10

CPU: Intel Core i5-13420H 13th gen

Ram: 8gb

GPU: NVIDIA GeForce RTX 2050

I've recently switched to linux mint and all my games work flawlessly except for overwatch 2. My FPS aren't great but most annoying is my ping spikes every 1-2 seconds which makes the game essentially unplayable.

I've tried it both on Steam and Lutris, turned my settings way down, and reinstalled drivers. Nothing seems to work and I can't find any thread on people with the same exact issue (and those with similar ones the solutions, see above, didn't work).

Is there any other steps I could take to try and fix this problem? I'm still a beginner on linux and don't know much.
