Hey everyone!

Just wanted to share that Umamusume: Pretty Derby officially launched on Steam in June 2025 with full Linux support through Proton. It's even Steam Deck Playable verified!

I've written a comprehensive guide covering:
- Steam + Proton setup (works out of the box with 9.0-4)
- Alternative methods (BlueStacks, MuMu Player)
- Performance optimization tips
- Troubleshooting common issues

The anti-cheat (CrackProof) is now Linux-compatible, so no more workarounds needed. Performance is excellent and installation is straightforward.

For anyone interested in trying this popular anime horse racing game, here's the full guide:
https://gamertagzero.com/how-to-play-umamusume-pretty-derby-linux-2025/

Has anyone else tried it yet? Would love to hear about your experiences!

Hi all!

I recently bought a GPD Win2 out of curiosity (Win 2, not Win MAX 2. This has a relatively old Intel chip specifically an m3-7y30).

I installed Linux on it, (since I use it anyway), and was somewhat surprised about the extremely poor game compatibility. (more on this further). Bazzite didn't want to install for some reason, I prefer Mint or Ubuntu anyway, but running or not running Wayland made no difference whatsoever. (Which makes sense tbf).

The graphics processor in this chip is an HD 615 which is "old" and "entry level", but according to these specs has pretty decent 3d performance https://www.notebookcheck.net/Intel-HD-Graphics-615.174029.0.html . What I'm saying is that it is not a display adapter. It has DX12 and Vulcan support.

And yet, almost any game I tried, on any runner straight up crashes on startup. (Cursed to golf, Horizon chase turbo, Xpand Rally Xtreme, Flatout Ultimate carnage, Crazy taxi, Call of Juarez Gunslinger). I'm convinced all of these games would run on Windows. I managed to get a handful of games to run, (Crash time III, Slay the Spire, the original Flatout through Heroic)

I installed Wine, the i386 build flag is enabled, I messed around with different Wine versions, and Proton builds (The latter of which did yield some result, Crash time and WatchDogs managed to at least launch (and run alright-ish on proton 9)

However all unity games crash with a Wine Access violation such as this:

Unhandled exception: page fault on read access to 0x00000010 in wow64 32-bit code (0x75a7cfd8).

I have the full dump, but honestly it seems rather low level, and pretty general so I doubt anyone would be able to look at it and present a solution, Still if you need it I can publish it.

This isn't the end of the world, I bought it more as a UMPC, but it has a gamepad built in, and it would be fun to play games on it, but more importantly I am a bit dumbfounded on the 'why'. I had an old Latitude 5470 which had the HD 530 Intel graphics (which I am fairly sure is basically no different architecturally), and I don't remember games refusing to even launch.

I searched a bunch on google, and came up short. Is there something I don't know? Are there some fixes for HD graphics? If this is as good as it is gonna get, can someone explain why? Basically please help my hyperfixation on this issue, I need to move forward with my life.

Thank you.

I just ran Skyrim via Steam and where the SteamLibrary is where I installed it, there is a compatdata pfx for each installed game separately. That can't be right. I install a certain WINE/Proton version for Steam, tell it to use it for all games, but surely it cannot be right (because huge storage space need) that it installs many hundreds of MB of that for each installed Steam game. I had to patch it with xact to have vocal audio in the game and had to do it into that, not some system-wide WINE.

Can you clear up my beginner confusion?

I use Debian 11 (bullseye), using a laptop with ChromeOS (I didn't think first before buying, oops) and I will respond with any required info if needed. I am not using Proton.

My system is a i7 4500u that got both the integrated intel gpu and another integrated gpu which is a radeon HD 8600M(which seems to be the main one for apps and games), i have recently installed Linux and was able to enjoy a great fps boost in roblox with sober, however the only thing i cant fucking run for my life are Proton games.

Currently, the only games(that i have interest and tried to run in the Linux system) are bloons td 6 and Dead by daylight, which both seems to need directx11, i also tried vampire survivors, which worked without me having to do anything at all, so thats great.

Yes, i have tried using most Proton versions, from GE, experimental, 10, 9, 5, 3, Yes, i tried to enable wine3d in all of them, no, it didnt work, dbd opens the anticheat but doesnt do anything after in most Proton versions, or it just show a message talking about directx, bloons is also the same but without the EAC of course.

I am aware that Proton needs vulkan which might not support completly or even half for old gpus, or something like that im not sure, but since Linux seems to have billions of workarounds, i come here asking for it, also if it would be able to stretch res that would be great, in case i needed to increase my fps.

I currently use ZorinOS with Xorg, in case someone asks.

Well, I know that every day on this forum there is someone asking this. Which distro do I choose for games? I've recently been looking to move away from Windows and I'm looking at every tool I use on Windows to see if it runs on Linux and now it's time for games. I play light and simple games like Celeste, Cuphead, Undertale and Hollow Knight. I know there are tools like Wine and ProtonDB. But I worry about gaming performance, whether the system can handle it. I know this depends more on the hardware, but a fear still comes to my mind that these games won't run well or won't run properly on Linux. I'm between ubuntu, fedora and arch for me to use, and I know there are distros focused on this like nobara, bazzite, cachy os, garuda, anyway... tell me your opinions please!! Furthermore, there is the issue of game emulation that I am curious about. But my biggest concern is the games in my Steam library.

Recently installed arch w/ hyprland fully on my laptop, installed steam setup proton and whatever else (note this isnt a gaming laptop its using intel integrated graphics) I've installed so far just 2 low end stuff to test the waters which are both deck verified and playable BUT both will go through the process of launching on steam, and then they'll just die, no proper error or anything , and I'm not exactly sure on what to do so I've come here for some hopefully insight to figure out what I should do to try fix it.

Hi!

I've recently made the jump to Fedora but also dual booting with Windows 10 and I am having a blast. The only multiplayer games I play are TF2 and Marvel Rivals which work perfectly on Linux for me thankfully.

The only thing that's holding me back from completely jumping ship is game streaming with Moonlight and Sunshine. Not sure if it's because I use an Nvidia GPU, but I always seem to have a laggy stream streaming from Linux compared to Windows no matter what I do, so I keep my dual boot only for this purpose.

I love to game in my living room streaming from my PC, so this is the ONLY thing holding me back from going all in. Is this an issue for anyone else? I know for a fact that Nvidia's driver are not as mature as windows when it comes to this aspect, so maybe that's it, but I'm curious if anyone else is having this problem and if it's holding them back as well :)

Before you get the wrong idea, I already know about having to update the kernel and mesa drivers and Linux firmware. The problem is, before finding out about all that, I tried to update the drivers normally and was testing using elden ring, which had been giving me a white screen, but for some reason this time purple pixels went everywhere on my screen and the computer froze. After a bit I force shut down my PC, and when I tried to reboot it neither the motherboard display port slot or the GPU slot worked. After a bit this seemed to resolve, but now when I plug in the cable to my gpu everything gets very sluggish just on the desktop. In mission center it says the clock speed is 0-2 megahertz and is drawing next to no power. I updated my motherboard bios, I updated the kernel to 6.14, I updated the mesa drivers to 25, and reinstalled the amdgpu firmware. Still the same as before. Did I somehow cause some kind of hardware damage or is it just because of the drivers still not working?

Hi folks,

since Star Citizen 4.1, the game no longer runs under Proton or Lutris. It used to work flawlessly with the `EOS_USE_ANTICHEATCLIENTNULL=1` workaround.

Now:

- Game hangs at load (no crash).

- EAC throws a generic "module error".

- User reports suggest a new "heartbeat" check was enabled.

This effectively blocks all Wine/Proton environments – even GE-Proton or Steam Deck setups.

🧠 Has anyone found a workaround? Or is this a hard lock now due to EAC changes?

Spectrum thread for visibility:

➡️ [https://robertsspaceindustries.com/spectrum/community/SC/forum/50259/thread/4-1-eac-star-citizen-no-longer-launches-on-linux-v\](https://robertsspaceindustries.com/spectrum/community/SC/forum/50259/thread/4-1-eac-star-citizen-no-longer-launches-on-linux-v)

Would appreciate any insights – even a “won’t work” confirmation. We’re not asking for native Linux builds – just to not be silently excluded.

Hey Guys,

I wanted to play ARK Survival Evolved with some friends of mine.
So i installed ARK Survival Evolved on my pc with the latest arch, the latest nvidia drivers, the latest steam and GE-proton10-10.
When i press start it will continue starting with the maintitle melody playing but no game pops up and after some time a crash message pops up.
I tried debugging for a few hours now and i kinda now what the issue is but not how to fix it.
Here's the error message:

and here's the proton log:
https://pastebin.com/yUmLfv68
(it was to large for the reddit post)

I tried to reinstall vcrun2013 with protontricks to repair the .dll, i tried reinstalling the game and the proton version and i tried to rebuild the prefix.
It is perfectly reproducable on my pc.

I hope that maybe someone of you, is in the mood to take a closer look on this and fix it or maybe you'll look at this post and see this shit and you'll have a little smile on your face, however i will give up fixing this shit :D
If you want a copy of this prefix or more data about the problem hit me up(I posted all available logs, the game logs mentioned in the proton log simply just don't exist) :D

I've recently reinstalled Fedora and nuked the Windows install I had sitting unused in a partition of my SSD.

My Steam library was in a shared NTFS partition, which I didn't want to remove because I would have to reinstall all the games. Before the reinstall, Steam wasn't able to launch the games because of the NTFS partition, but symlinking the *.acf files and installation folders of every game over to ~/.local/share/Steam/steamapps/(common/) solved the issue.

After the reinstall, the issue returned and that workaround didn't seem to work anymore. Plus, I tried uninstalling one of the games and reinstalling it in ~, but to no avail, which leads me to think the cause of the issue may be different this time.

Relevant details in summary:

• OS: Fedora 42
• GPU: Nvidia Geforece GTX 1660 SUPER (no iGPU)
• GPU Drivers: Propietary from RPMFusion (575.64.03)
• DE: KDE (Wayland)
• Steam library in NTFS partition (game files symlinked to ~/.local/share/Steam/steamapps/(common/))

Hey all. I hope this is the appropriate place to post this, so here goes...
I am looking to upgrade my PC sometime soon and want too switch from Windows to Linux.

I already have quite a good grip on using Linux in general, having used it personally from time to time on a second PC I own, and using it exclusively at my place of work (I do web development and Linux server administration). I also own a Steam Deck. So it's fair to say, I know my way around Linux and am not afraid to use the console.

My main experience is with Debian and Debian-based distros (mostly Ubuntu in recent years). I am open to new things, especially if they are better suited for the task at hand, but I also don't want to make it too hard on myself. So my question is, should I switch to a different distro, and if so which one?

A friend of mine has been using Manjaro as his daily driver for quite some time now and he swears by it. He is a bit of a crack though and doesn't mind tinkering with stuff. I know Manjaro comes "with batteries included" as opposed to "vanilla" arch, but how many batteries does it come with? I don't mind fiddling around with things, but I mostly want it to "just work" out-of-the-box.

I have also been looking at things like Bazzite or (thanks to this subreddit) Nobara, but I might want to things other than gaming and browsing the internet further down the line, like maybe hosting a server or doing some programming in my spare time. Are these any good for that or should I just stick to a less gaming-focused distro?

Or should I just stick with Debian, since I am most familiar with it (using it on my main work PC and the servers I tend to at work)? I was considering Ubuntu or a derivative like Kubuntu, but I am not a fan of how snap is integrated into the system and it feels like everything is running in a sandbox, which is not ideal for if I actually want to do some programming. I know since I have Ubuntu on my work laptop and it can be a pain sometimes.

I am mostly torn between Debian and Manjaro.
Manjaro does look tempting, since it seems to be updated on a more frequent basis. But I also like the familiarity of Debian...
So, any advice is much appreciated :)
