I am unsure what share Steam Deck has in the gaming industry, and I don't know if that share is growing. I am wondering whether the Steam Deck is encouraging new game developers to give more consideration to Linux and Steam Deck compatibility.

Steam do not seems to have a native linux build of Celeste, so i am using proton for compatibility.

When i try to run the game without any configuration, it just closes without any message.

Launching the game with `FNA3D_FORCE_DRIVER=OpenGL %command%` seems to fix the closing problem, but the game graphics are very problematic (seems that openGL is trying to emulate the light masks inverted):

FNA3D_FORCE_DRIVER=OpenGL %command%` launch option

Browning a bit, i found that use vulkan instead of opengl (`FNA3D_FORCE_DRIVER=Vulkan %command%`) could work, but when i try it i get these error messages:

`FNA3D_FORCE_DRIVER=Vulkan %command%` launch option

System information:
- Arch linux 6.15.5
- Wayland
- NVIDIA GeForce RTX 3050 6GB Laptop GPU

I recently tried to use the proton ge 10-8 on my steam using the proton plus, I managed to download the proton and tried to load the game, but only a loading screen appears with the game's photo and closes when it finishes loading, while in the others it doesn't even load anything, it just closes.I recently tried to use the proton ge 10-8 on my steam using the proton plus, I managed to download the proton and tried to load the game, but only a loading screen appears with the game's photo and closes when it finishes loading, while in the others it doesn't even load anything, it just closes.

hello all. i have recently switched from windows 10 to linux mint, and i have run into an issue. almost every game i've run on steam which has had noticably slower fps, and, in some cases, have frozen my entire computer and required me to restart my entire pc. it isn't a problem with games that don't require much processing power, but for the games i typically play (grand strategy games) it has become a serious annoyance having a slowdown to 20-30 fps, and in the case of victoria 3, has made the game almost unplayable, running at about 5 fps and crashing whenever i try to change graphics settings. i would prefer not to have to go back to windows or change distributions, because apart from this my experience with mint has been great, but my primary use for my computer is gaming so i will do what is necessary to resolve this issue.

I'm probably getting insane, but here is an idea:

Could I run a "dual gpu" setup on Linux?

Would it be possible to use an AMD gpu for gaming (monitors are connected to it) and a second gpu, a Nvidia, for stuff like rendering (maybe even recording with OBS via nvenc)?

Hello peeps so when playing the ea bf2 my game uses 15 gb of ram which I think is what causes my system to completely freeze and I have to force restart it every time I’ve confirmed this doesnt happen on windows but my windows drive as a 10-15 year old hdd that takes years to even load the task bar so what can I do proton tricks? Wine version I dont know abt? I use proton ge 10-4

Rtx 3070 lhr

R5 5600

16 gb 3600 mhz ram

Newest version of linux mint and newest kernel and everything is up to date (yes including drivers) any help?

Please and thank you guys

This is a very niche problem but does anyone know how to get past the operation flytrap bug in prototype 2? The mission gives you an objective to claw pounce on a soldier but after doing that the objective is never satisfied, stopping me from competing the mission. I’ve looked at a few fixes that work on windows by limiting the fps to 30 but not sure how to get the result on linux through lutris. So far I have set the cpu cores to only use 1 and putting “DXVK_FRAME_RATE=30”into the command section but no luck.

CPU:ryzen5 2600 Gpu:Rx 470 4gb Ram : 16gb Os: Linux mint Kernel:6.8.0 Wine/proton used: protonGE 10.4

I've been moving to Linux as a daily, mostly for gaming, but I found certain games were only using cores 8–11 out of my full 32-core setup. Turns out gamemode was the culprit. It's been locking CPU affinity even though none of its config options mention this.

I tried setting renice to 0, disabled GPU optimizations, and found out realtime was deprecated. So, only disabling gamemode stopped the affinity lock and brought performance back up.

On lower-core-count machines (like Steam Decks or typical AMD systems), it's probably less noticeable, hence why I haven't found anyone with a similar issue online.

If you're getting weird slowdowns, check your affinity with something like htop or taskset.

If anyone has a fix let me know, I’d love to get the benefits of gamemode without the core lock. Otherwise let this be a PSA to anyone who might be having performance issues.

I have reported this on the Repo, but just also posting here for awareness as alot of people may not interact with gits.

Hi, I need help. I've just installed Arch Linux on my laptop and I wanted to play some Skyrim. I downloaded Steam and Stardew Valley, both run perfectly, but I downloaded Skyrim and when I try to launch it the launcher will pop on the screen for a fraction of a second and then close. I'm new to Arch Linux and I can't really find what's causing this problem.

Basically when I run games with gamescope, whenever a steam notification comes up, the active window seems to change towards the notification and in turn makes the game quickly flicker whilst the notification comes up and then once it's gone. It doesn't do it running games without it.

OS is CachyOS, Hyperland and CPU/GPU are AMD.

Anyone have any ideas?

I have been playing 1.21.60.10 for a while now and everything was working pretty much out of the box, but now everytime i try to get to the skins tab or i enter my world it will just crash for some seconds.....

It's one of the latest versions so i get it might not have proper support atm.What i wanna know is, which version should i play?....I don't even play minecraft, just bought it today to try it out but no clue wether i should use something like 1.18 or smt, are there any big changes in the middle of 1.18-121?

EDIT: I made a different desktop file for mcpelauncher appimage and turned off "multiplayer game" or smh from the world settings, back to the track for now.

Hello, I'm trying to install the old Harry potter pc game, the one from the first movie, I'm using lutris and trying to install the game using an ISO image, it all seems to work well, I get the installation prompt from the game, but at the end I get an error message saying that RPC failed, I'm not sure what that is or how to fix it, does any of you know? Could you help me figure it out? Or should I just try another method of installation? Thanks

I'm having problems starting Yu Gi Oh Master Duel, the game starts and closes on this screen, I tried using several versions of proton, as well as this command that I found in ProtonDB: gamemoderun PROTON_USE_WINED3D=1 %command% nothing works.

Is it worth using a Windows virtual machine or setting up dual boot for games that don't run on Linux at all?

Hey guys really struggling here and not quite sure how to get what I want, maybe you can help me out here.

What I have:

AMD Ryzen 5800x (so no iGPU)

32GB RAM

RTX 4080 S

Many SSDs

What I want:

A Linux Host on which I can play games via Proton and a Windows VM for Games, that aren’t able to be played via Proton (as well as some other Windows exclusive stuff I need to do).

What I’ve tried:

Linux Mint & PopOS!. Some of the features worked, but not all of them. I tried following different instructions many times and tried especially with PopOS! about 3 installs and I wasn’t really able to do what I want. I wanted to try now with Manjaro since many people said this was the distro to go for, but I would go back to Pop or Mint, if that makes it any more possible.

ATM I dual boot, but would really like to get everything under one Main OS and I would prefer to use Linux over Windows in my daily use for as much as I can.

I’ve read a lot about getting a second GPU or using the iGPU, for the Host OS and passing the Nvidia GPU to the Guest OS (Windows). But thats not what I want, I really want to do as much as possible on the Linux Host (including gaming) and then, if nessesary use the Windows VM and passthough the GPU to that. While being in the Windows VM I do not need to do anything on the Linux Host.

Most what I’ve read about this was pretty sparsly explained and I’m no Linux Guru, so maybe that’s part of the problem. But I’d really like to get more into Linux, so here we are.

I installed Steam on my laptop with ubuntu and applied the linux filter. But some games that don't support linux are appearing along with Install option. I know FIFA and R6S is not supported which I am sure. Any idea why this is showing?
