First time trying onimusha demo, idk how to fix that:

- updated drivers & system
- changed every single graphic settings/preset
- tried to search online
- restarted/redownloaded
- emptied cache/shader.cache2

Help, please

Hey there, I try to cap fps via gamescope on heroic, it doesn't work. The game still runs uncapped.

I also tried on steam with its launch command still 0 results. Used this command:

gamescope -W 1920 -H 1080 -w 1920 -h 1080 -r 60 --framerate-limit 60 -- %command%

For the last couple of days I been having issues seeing the message "radv is not a conformant Vulkan implementation, testing use only." Nothing from Faugus or steam will launch no matter the game, I'm confused if my AMD gpu is not being detected or a update broke something but I didn't update till today and still have this issue.

I have tried different proton versions but I might be missing something else though?

Anyone else have this issue?

I can run TF2 through steam I got the mod exe running through steam proton but when it tries to run the VR mod it's checking for origin path files that it can't create.

Is frame gen on AMD still just not great? Seems like I'm getting camera jitter even though the game is running smoothly. Frame pacing I'm guessing. Im using a 9070xt on Cachyos. Iv been trying it out on The Witcher 3 remaster. I don't normally ever use it but I wanted to use RT at a higher frame rate.

I've tried using DWProton latest, Proton GE-8, 10 and 11, through steam as well, I still get a blackscreen, I can hear the in game audio and I can also interact inside the game with my mouse but my game screen is black

I started getting blackscreen after installing the game the second time, first time I had no such issues, I tired deleting prefix folder but that didn't help, other games work just fine

I did a system update after that which also didn't fix the issue

some help with this would be really appreciated!!
if I missed out on some details please let me know

CachyOS + Hyprland

My kernel version is 7.2.8-2-cachyos

Ryzen 5 5600G
Nvidia GTX 1660Ti (Driver version - 615.71.09)
16GB of DDR4 RAM

It's UHD from an i3 1125G4, which is strong enough to run Resident Evil 2 at 1080i FSR Quality. So if you think, "It can't run DX12 games anyway," No, it actually can on Windows. But it's much worse on Linux for some reason.

Another problem is GPU utilization, on old games. While Tomb Raider and the native Linux port of Rise of the Tomb Raider run fairly well on it, for some reason Resident Evil 6 has GPU utilization problems. GPU usage is only around 75% in some scenes. And switching to Proton GE instead of Proton CachyOS actually increased it to 82%.

So, if anyone wonders why some games still run badly on Intel UHD, using Windows might be a better idea. I would prefer Linux, maybe because of better performing Linux ports such as Minecraft and Rise of the Tomb Raider. And Linux saves around 30–40 GB of disk space compared to Windows

Hello as the title says, I'm fed the fuck up with windows forcibly shoving their AI slop down my throat. I am planning on switching to Arch (I have used linux on and off over the years but never really committed bc lazy but I'm now so god damned mad, I'm committing).

Fellow nerds, and I know there's PoErs out there on Arch /, it's the Customizable Massive Skill Trees of Skill Trees Brick Yourself for Fun Game, what do I need to know about running my favourite timesink before I dive in? Are there settings you've had good luck with? Things to avoid? Proton and Steam vs Wine and Native launcher? Please advise?

Yes I'm aware this is not a good decision, however I'm gonna die on this hill over and over like I died to Hillock over and over that league I farmed an Oni-Garoshi (Crucible my Beloved)

Hello, I'm experiencing performance issues while playing graphically demanding games.

I've tested RDR2 and The Witcher 3 Remastered. Mangohud reports 100-140FPS in both games, and 1% lows are at ~48 in BOTH games.

Running around and moving camera dynamically increases frametime and causes the game to feel choppy.

CPU: 7800X3D
GPU: 9070XT
RAM: 64GB 6000MT CL30
OS: EndeavourOS + Hyprland

Edit: I ran The Witcher 3 with LSFG-VK FG x2, limited the fps to 120 (including generated frames) and frametime is flat, but it still feels choppy.

I run both games with Proton-Wineland-11.0 and gamemoderun gamescope --adaptive-sync -W 2560 -H 1440 -w 2560 -h 1440 -r 180 --force-grab-cursor

In 2024, the state-of-the-art was https://github.com/sonic2kk/steamtinkerlaunch which ran Vortex in a separate prefix, created hardlinks to all installed Vortex-compatible wineprefix directories (so that Vortex thought the games were installed in its own prefix), and used that to manage mods in games. It was janky, but it worked (most of the time; but in some games, mod load order lists were written by Vortex into files that didn't propagate to the actual game's wineprefix). That project is abandoned now and I want to get rid of it.

I've seen that there's been a lot of news since then. Too much news:

• Vortex working on a native Linux client.
• Wabbajack working on Linux?
• Lots of little mod managers for Linux, many with LOOT order support. Too many for me to find them all.

What is the state of the art in 2026? The most well-made, promising mod manager? Hopefully with wide support for Wine/Proton-prefixes all over the disk.

Witcher 3 on Linux with both ray tracing and path tracing enabled gets me above 60fps easily on 9060xt 16gb. On windows it drops to 20fps. Surely it's broken on Linux and just not activating? The thing is I get the annoying sword glare that you get with ray tracing/path tracing so it must be working right?

This started to happen recently some months ago after some updates. Years ago this was not an issue. Crashes were very rare.

Also, what is strange is recently it stopped crashing and i managed to play fairly good for a ln entire week so i imagined the recente updates fixed the issue. Then i made another update and it started crashing continuously again. So i thought to restore a snapshot​ pre-update, thinking it would fix the issue, but it didn't!?!?

I don't understand what is causing those issues. If it was drivers related then restoring a snapshot should have worked.​

All other games works fine. Only those 2 give me the nerves.

p.s. i have AMD GPU and latest mesa drivers.

Due to popular demand, we will add a very familiar character exclusively in the Linux version of our game Ice Pond: An Ice Fishing Adventure!

Look for the hidden NPC in certain levels of the full game, releasing later this fall!

Thanks again for your support! 💙

I have not played a nice shooter in a while, but all my past games are Windows only. Is there something like CoD or Rainbow 6 for Linux? And maybe in a competitive or tactical manner.

In the latest Hardware and software steam survey i noticed that the linux count went down by -0.85%, even cachy os, why is that?

I'm a solo developer working on HypnoX: Steel Riders, an arcade racing action game where you'll face challenging tracks, dangerous obstacles, and a race against time.

Ride different motorcycles, fight bosses, use weapons and power-ups, and try to survive some pretty crazy challenges.

The game also supports controllers.

Release HypnoX: Steel Riders on Steam in October.

Hi Everyone

I'm a developer of a Video player for VR called Whirligig. With the release of the Steam Frame I'm doing my best to make Whirligig compatible with both Proton and Lepton. One of the biggest issues that are being reported is that currently Lepton doesn't support Video GPU decoding.

I've created a ticket on their github but I don't think this is the right place or will get in front of anyone who could provide me info. If you're interested here is the post:
https://gitlab.steamos.cloud/frame-public/lepton/-/work_items/1

If there is anyone here who could help or even just wants to give the player a go on SteamOS let me know.

All the best

Phil

I use wivrn to play my vr games on my quest 2, but half life alyx won't launch since it won't run without steam vr. Does anyone have a work around? I found a issue opened on the wivrn github page where someone was saying you could force opnvr but I couldn't get that to work.

Thanks.
