Just posting in case someone faces a similar issue in the future.

I spent two days debugging instant shutdowns on my PC (3090 FE, 7900X, 64GB RAM). The system would just die mid-game, completely reproducible. PSU clicks off, no kernel panic, no freeze, no logs. Just instant death.

I've had this issue for at least a year, maybe longer. Since I don't game that much and some games like Anno 1800 always worked fine, I never properly investigated. Naturally I assumed my 800W Enermax Max Tytan was damaged or couldn't handle 3090 transient spikes, so I ordered a 1200W be quiet Dark Power 14.

Strangely, Windows worked perfectly on the same hardware. (I still use dual boot for BF6 sometimes, but also tested Witcher 3.) So did Blender CUDA rendering on Linux at 600W for hours. Only Linux gaming killed it, both native and Proton. On X11 and Wayland. (Tried AwesomeWM and Hyprland)

Witcher 3 killed my PC once it loaded the game. Baldur's Gate 3 at a specific camera angle and position in Baldurs Gate city. GTA V usually when I changed graphics settings and unpaused.

I started limiting GPU power via nvidia-smi. 300W crashed. 200W crashed. At that point my whole system was pulling maybe 350W. An 800W PSU doesn't trip at 350W.

Set up remote logging to my NAS since local logs died with the system. Captured GPU stats, temps, kernel messages, journal, strace, bpftrace, ltrace. Nothing abnormal. System running fine, then just gone.

Then I swapped in a 400W PSU I had lying around. At 150W GPU limit it was stable. At 200W it died the same way. Both a 400W and 800W PSU failing identically was suspicious. Yes, 400W is underpowered, but I expected at least different behavior.

Switching from nvidia's open kernel module to the closed proprietary driver eventually fixed my issue.

Arch merged their packages so you get the open module by default, even if you install nvidia-dkms. I grabbed the .run installer from nvidia's site, installed proprietary, and the system has been rock solid at full power since. I eventually installed nvidia-beta-dkms via AUR.

I have no idea what the open driver does differently that causes this. If you search for "PC instantly dies in game" you'll mostly find recommendations to buy a new PSU. And nvidia-open is recommended by both Nvidia and the Arch wiki over closed proprietary.

So if you're facing a similar issue where your PC dies instantly mid-game, reproducibly, maybe try the proprietary driver before buying new hardware. I canceled my PSU order and consider writing a bug report once I am less annoyed of wasting my last two vacation days.

So I’ve tried connecting my controller, a DualSense ps5 controller, to my CachyOS pc to play games. It works just fine in Absolum, but when I try to use it with Resident Evil 4 Remake it won’t recognize it.

My Xbox controller won’t work either, but I also have to connect it via cable because it won’t connect via Bluetooth.

I’ve tried different proton versions and nothing. Different settings in steam input either.

I haven’t tried proton-ge cause I don’t know if it would actually have any fixes.

Any help is greatly appreciated this one hurdle is the biggest pain in my ass with Linux gaming and I am desperate for a fix lol.

It’s not like Steam doesn’t see the controller. It recognizes it and even opens the steam overlay in RE4, just RE4 doesn’t recognize it. It even says its compatibility is “unknown” in the info page.

Hope this helps, I’m willing to do statin can to assist if anyone is willing to help.

Update: I tried silent hill F and it will let me skip credits with a controller, but once it gets to the title screen it stops…

Update 2: I installed udev rules for both DualSense and Xbox controllers. After a reboot the DualSense is still wonky but my Xbox controller works. I’ll consider this solved, but I’d love to get to an underlying issue. If someone has any ideas or pointers where to start looking at the DualSense issue I’m all ears.

i have a second installation of elden ring that has been downgraded to an older version[as shown in this video] to check for compatibility with an outdated mod. the second installation is on the same drive as the main game. if possible, i would like to be able to launch either version from their respective executable, keeping the files completely independent of each other. the secondary installation is not located in the steamapps/common folder and as such there is currently no way of launching the older version without overwriting the files of the latest version with that of the former, and i would like to keep the files of the latest version untouched

i am using linux mint cinnamon kernel 6.14.0-37-generic

Bazzite: Stable, Linux 6.17.7-ba20.fc43.x86_64, KDE Plasma 6.5.3, AMD Pyzen 5 2600, AMD RX 9060 XT, Steam, GE-Proton10-25 (hope I didn't miss any important data, if so please tell me, even if it's not important for this topic, because I probably will have to create more post somewhere else for some troubleshooting)

I already looked up the game on protondb and created the missing cfg file and the game would now boot up, but shows a blackscreen and immediatly want to create a mini dumb. After creating the mini dumb and looking into it, there are the errors Could not open midi device 0 (Err:3) and Could not open midi device 1 (Err:3) Does anyone know what I need to do so I could play the game?

I'm having issues with Steam lately.

It takes a very long time to load and then gets stuck in Offline mode. Can't download games, can't sync saves, can't load the store... It says I have no internet access while I clearly do.

What I tried so far :

- Using Ethernet over Wi-Fi,

- Deleting all the Steam related files and packages and reinstall everything (worked for like 2 days)

- Updating the system (everything's up to date already)

System information :

ThinkPad P14s Gen 5 AMD, Debian 13 Gnome (trixie, main, contrib, non-free, non-free-firmware)

Does anyone had this issue ?

I have been plagued by this bug just way too long at this point. For some reason there seems to be a coherent bug (no matter if Nvidia(earlier) or Amd(now)) where for some reason the Display Server Protocol just mixes up something and only gives me less than a third gpu util. The only fix i have found for this issue is to just alt tab out and back in again, and sometimes it jumps back to >80% gpu util and sometimes it just stays low. Most notably are War Thunder and CS2 in that regard, which might have to do with their native builds, although me already running CS2 in wayland only mode for example.

Pc-specs:

• RX 6950 XT
• 5950X
• KDE (Wayland) 6.5.4
• Kernel: 6.17.12-300.fc43.x86_64
• Fedora 43
• 32 Gigs Ram

Displays:

• FULL HD, 60hz (DP)
• 1440p, 170hz (DP)
• FULL HD, 144hz (DP)
• 4k 60hz TV (Hdmi) (Disabled, only used in my Bazzite distro)

I also want to add that none of the components is thermal throttling and my main only lead or suspicion is a bug in wayland, but the more i look for similar issues the less i find about it :/

Maybe someone has a similar bug or already fixed it, would be lovely :)

Oh and no, using Gamescope for example does not fix it beforehand.

You see, the limit is 162w. But no matter the game, it will now exceed 145w(which is the limit if amd overclocking is disabled). Same system in my fedora 2nd install show the correct powercap and also reaches upto 162w. But on arch (endeavour and cachy both) it can only reach upto 145 and then power throttles it(as seen in mangohud). Would appreciate any help to uncover underlying cause/issue

Hi everyone, this is my first post on this community.

I have been using Linux for a long time on my laptops and work PC, but I have never used Linux for gaming on my main PC, which runs Windows 11. Recently, I have been experiencing system crashes, instability and all the other joys that Windows has to offer on this very PC.

Since I use Arch at work, I am intrigued by CachyOs and would like to try it out to see if it could solve my problems.

My configuration is as follows:

• Ryzen 9 5900X
• Asus-B50 XE
• 32GB RAM (DDR4)
• Asus TUF Radeon RX 7900XT
• Samsung 960 EVO 500GB
• and various non-NVMe drives.

Would you recommend using a dual boot system or going all-in on Linux?

How do I manage Asus peripherals and check the health of my drives on Linux? Is there an alternative to Adrenaline that allows me to adjust my graphics card settings (e.g. power, maximum FPS, etc.)?

I mainly play Arc Raiders and Helldivers 2 in multiplayer on Steam and Heroes of the Storm on Battlenet. I've seen that Arc Raiders is compatible with Steam Deck, so there shouldn't be any problems running it on Linux, but are Battlenet games supported?

Sorry for the barrage of questions, but I'm really keen to make the switch to Linux.

Specs: https://imgur.com/5jtiBt5
The trouble:
-- Diablo 2 Resurrected, Will ABSOLUTELY get into actual gameplay (seeing the towns, move around) but https://imgur.com/a/bPkSpuu. OG graphics work fine, but I want the newer/fps ...
-- Warcraft 3: Reforged - Completely black graphics, no audio whatsoever, never see anything.

Using Lutris, and have to run battle net with proton 10, to even get into diablo, I've tried other protons/wine/ for warcraft and no change. I assume some GPU (mesa?) update borked both.

Out of nowhere, my FPS in Metaphor:ReFantazio has dropped from 120, to around 13. Attached is a screenshot of the issue.

I’m not really sure what to do next. I’ve tried re-installing the game, multiple versions of Proton (including GE, CachyOS, Experimental, Hotfix), rebooting the system multiple times, starting the game in both desktop mode and gaming mode…

I just want to try to play my favourite RPG this year. It was working fine up until now for several upon several hours and I have no idea what is causing it. This does not seem like a common issue as Google searches have also turned up nothing.

This issue does not seem to pop up with other games I have tested so far.

I am running Bazzite, with an AMD 9070XT and 5700X3D.

I am new to Linux and a while ago got a 9070 XT and was very comfortable using it on windows with access to fsr4. But now on Linux I haven’t figured out how to get fsr4 to work. I am using pop os and have mesa 25.1.5 and no idea how to update it since I have heard mesa 25.2 has some built in fsr4 stuff but I’m not too sure what that’s about. I’ve so far tried everything from Optiscaler to manually updating the fsr dlls to just adding things into the launch arguments and updating to the latest version of proton (idk if using proton ge will help in any way but if so do tell me). I’m at a complete loss for how to continue and how to get fsr4 to work on Linux and would really appreciate some help because everywhere else I look either is for a different os or mentions 5 different things as assumed knowledge I have never heard of before as a Linux noob. So any help here would be much appreciated

So I saved my 2012 sony vaio by upgrading it's RAM to 8 gb and installing linux mint. I was an avid gaming enthusiast till my college years i.e. till 2009. Now the itch is back. Can anyone guide me which game to install or can install on linux mint, I used to play Age of empires, civ4 etc

Just what the title says basically, but i'll explain. Having to rotate the wheel a full 360 degrees or more to do a hard turn makes the game not as fun as just using the arrows on the keyboard, also makes it easy to lose track of the buttons that i've set to do different funtions. how can i set it to do a full turn at like 90 degrees of turn, maybe 135 degrees max?
i tried using jstest-gtk and calibrating by only turning the wheel 90 degrees but that had no effect. affect?

I have a laptop im just screwing around with, 4gb of ram, Jasperlake UHD intel graphics and 128gbs of storage. Im just trying to make this as fast as possible performance wise.

Have you guys found any difference between in the two in consistent performance? which was generally better?

Is cachy OS better for running games on low end hardware basically, or does it not really matter?

Hi everyone,

I am currently running ubuntu with thin 14' acer ( 7840u cpu, igpu 780m, 16gb ram ).
I didnt have much troubles on windows as it came with windows 10 and it worked right out of box. With laptop stand, air would flow in properly and it never went beyond 80c temperature while gaming.

When I switched to linux I had trouble with temperatures over 100c and shut downs. After a lot of investigations and trying out everything I could, I ended up using ryzenadj to make a gaming script which basically set up my tdp to 25w. It gave me more fps than windows and it stabilized my temperatures to around 70-75c.

Now if I got this right, it means I basically told my laptop to use fixed ammount of power instead of jumping around, I've also set my up max temperature do never go beyond 80c. Is that a good setup that will force fans to spin faster when needed and to deliver optimal power when gaming?

So far this has been the only thing to allow me to game and to keep temperatures low and fps high, just not sure is that a proper method for linux, ryzen cpu/iGpu and thing laptops that don't have any access to fans in bios.
