Some months ago I read something about gaming specific linux kernel that I can install on existing os like linux mint or ubuntu and then that gaming kernel would give me optimized gaming experience on my linux machine. So is that actually a thing or was I hallucinating. And another thing about gaming in linux is that, my 1000 hz polling rate mouse just doens't work on linux. it' just gives me really less polling rate like office mouse, and another problem i face on linux is, I mostly only get 60 hz support only with my display. so how is that everything changed on linux??

I wanna play

CPU: 5600x

GPU: RX 6600 8GB

RAM 16 GB (8x2) DDR4 3200 Mhz

OS: CachyOS 6.17.8-2 + KDE PLASMA 6.5.3 with Wayland

Hey guys, I'm getting really high CPU % in Cyberpunk 2077 and RDR2 (80 - 90%), and in the first game it is not even using all my GPU. I'm playing both on medium-high settings without any mod. I'm kind of new to Linux but when I played these games on Windows my CPU usage didn't go higher than 50%. I've already tried changing compatibility on Steam and updating drivers/kernel.

Idk if it could be a Mangohud bug because even with those metrics I thiiink my game performance is what it should be with my specs, but it is still weird.

Any help is very welcome, tysm.

Yesterday I finally installed Linux. Since I had trouble with CachyOS and I am completely new to Linux I tried Mint and it worked.

After some trouble I made battle.net work. I installed it with Lutris and I start it with steam in compatibility mode with Proton 10.

Unfortunately I have around 10-20 fps less than I have with Windows 11. My Hardware is a 7800x3d, a 7900xt, 32Gb Ram and a Msi B650 Tomahawk.

Is there anything I might be able to do, to get more fps?

TL;DR: HDMI audio was stuttering and none of the usual culprits (PipeWire latency, GPU clocks, suspend settings, etc.) were the reason. Real cause was PCIe link instability!

I recently built a new couch + TV gaming PC with an Intel CPU and Nvidia GPU and installed Bazzite. Games ran great with high FPS, but I had persistent audio issues—a split-second skip every 30 seconds to a few minutes. It happened even with very lightweight or emulated games, which led me down a rabbit hole trying to fix it.

Turns out, this is a very common problem when running audio over HDMI. There are numerous Reddit posts and a massive GitHub thread with many suggested solutions. Here's a guide summarizing everything I found and my experience debugging this:

1. Tweak Pipewire (Bazzite 43 already implements most of this by default.)
   • Adjust the PULSE_LATENCY_MSEC environment variable.
   • Modify min & max quantum.
   • Set up realtime scheduling for Pipewire threads in the kernel CPU scheduler.
2. Disable suspend for HDMI audio sinks
   • Especially important when going in/out of sleep.
   • Example here
3. Disable aggressive GPU power-saving
   • Lock GPU clocks, or at least memory clocks.
   • Use LACT for AMD or nvidia-smi for Nvidia
4. Check for other apps stealing the audio sink (this is rare)
   • For example, speech-dispatcher
5. Enable kernel preemptiveness (Also default on Bazzite 43)
   • Example discussion

Many are just “try this and see” suggestions, which is frustrating for intermittent audio skips. I recommend a methodical approach:

1. Check Pipewire buffers and sinks
   • Use pw-top to watch for under-runs/overruns or apps stealing the sink.
   • Enable Pipewire logging if needed.
   • In my case, there was no correlation between Pipewire and audio skips.
2. Monitor GPU clocks
   • Check if audio skips correlate with clock changes.
   • In my case, they didn’t—the issue was completely different.

• Video: Frames are computed on the GPU using textures, geometries, and assets loaded into GPU memory ahead of time. Only small updates—commands, movements, physics—are sent live over PCIe per frame.
• Audio: Streamed from CPU threads (Pipewire, ALSA) to GPU memory at 2×48k samples/sec, or higher for 5.1/7.1 channels. AI chatbots tell me that GPU buffers can be as tiny as 10–50ms and hardware-specific, not software tunable.
• HDMI output: The GPU’s HDMI block interleaves video frames and audio samples with latency synchronization and sends them over the HDMI link.
• So HDMI audio is the proverbial canary in coal mine all the way from CPU ==> GPU ==> Audio -- it is very low bandwidth but is a continuous latency-sensitive stream, and any latency hiccup along this path causes an audio dropout.

All of the above solutions unfortunately did not fix my issues. I couldn't find any fishy pipewire errors/logs or GPU clock changes that correlated with the audio dropouts.

Here's what I eventually figured out:

• Run sudo nvidia-smi dmon -s e
  • This command shows various errors and I saw an ever increasing count of PCI errors.
  • All of them were correctable errors, so nothing functionally failed and reported back to kernel logs as hardware issues.
  • These PCIe correctable errors are typically CRC (or similar) errors, due to poor signal integrity on the link.
  • The hardware automatically retries the packet which causes a tiny microseconds worth latency hiccup; few errors won't matter, but 100s of errors per second could make a big difference.

Solution

1. Fix signal-integrity issues: These issues originate due to hardware, so starting there is a safe bet
   • Reseat your GPU
   • Get rid of any PCIe riser cables
   • Check for bent pins, remove debris from the PCIe slot
2. Avoid PCIe link retraining as much as possible:
   • Manually fix the PCIe link speed in your BIOS instead of letting it auto-negotiate.
   • Make sure you don’t accidentally lower your NVMe SSD speed or misconfigure its link. Use: sudo lspci -vvv <device> | grep -e LnkSta -e LnkCap to check each device’s current state and capabilities.
   • Disable PCIe ASPM and other PCIe low-power link states. This slightly increases power draw.
   • Just doing this dramatically improved my audio — instead of a dropout every few minutes, I only got a split-second skip once in four hours.
3. Eliminate PCIe errors entirely:
   • Use a lower PCIe link speed that produces zero errors. Example:
     • My GPU supports Gen5, but my CPU only supports Gen3 — and even Gen3 still produced a lot of correctable errors.
     • Dropping to Gen2 eliminated them.
   • Very few games are PCIe-bandwidth-limited, so don’t stress about lowering link speed. Raise it back up only if you can prove a game is PCIe-bound. This barely matters.
4. If all of that didn't help and you do have a lot of PCIe errors, you may be dealing with a poor PSU that has too much noise or a defective motherboard :-(

After doing all this, Bazzite 43 worked perfectly out of the box. Not one audio skip.

• Some users on the GitHub thread see this only with Bazzite or Fedora, not sure why. If nothing works, try a different Linux distributions like CachyOS (avoid Nobara as it's also Fedora based).
• Others observe this as a problem only with HDR enabled, again not sure why. Probably requires more methodical analysis. ¯\_(ツ)_/¯
• Tip: AI chatbots are surprisingly good at pointing you to the right commands and tools. They helped me discover PCIe errors, which I wouldn’t have checked otherwise. And they helped fix the language for this post as well :-)

yo good day, i dont know if this the right group but maybe there is someone here using a fake ps3 controller im on arch endeavour os my fake ps3 controller is not working vis bluetooth now its not connecting i install bluez-plugins-ps3 but still its not working maybe there is someone can help me i cant find any solution to fix my prblem thanks

(Fedora 43 Workstation) (Nvidia 3060)

The game launches and works perfectly fine - until maybe 1 or 2 minutes into the match, the game crashes completely. No matter the version of proton, I tried many of them, like GE10-25, or hotfixes, experimental - crashes no matter what.

Came back trying to run retail wow after a few months. Its always been fiddly and oddly specific about what wine version to use, but I always got it working without really understanding what i did.

But this time was different. Tried maybe a dozen different runners, some of them would get me into battle.net, none would be able to launch the game. Wasted maybe an hour or two. Then i gave up and added battle.net launcher to steam and proton 10.0-3 everything would work instantly. Almost went back to install the game on my w11 (im dual booting).

Should I just assume lutris is dead in the water and not worth it anymore or is there something going on that i dont know?

Switched from Win11 to Fedora Kde Plasma on my second SSD, i got the latest Nvidia drivers and proton working, but when i launch a game ( for honor ) it takes like 10 to 15min to launch. any way to fix this? i tried some fixes like disabling vgui and downgrading the mesa but its still the same. thanks in advance

I recently shifted from a Windows 10 OS to Fedora KDE. I havent had any major issues with gaming on fedora aside from learning that some games do not run on ntfs format hard drives. Yesterday I installed nier automata and since it was platinum on protondb. I thought there wouldn't be any problems but I couldn't get it to run. I tried many different things like:

1. Moving the game directory to OS ssd. (This solved my omori problem)
2. Trying different versions of proton but still nothing.

Steam says it plays for a second and stops after a few second without any error and any screen .

I am using flatpak version of steam and my system specs is:

• Intel i5 3350p
• GeForce GTX 1660 Super
• 16 GB DDR3 Ram

Also my drivers is 580.95.05

I have tried proton hotfix, experimental, 9, 7, 6, all have this issue. Computer runs Arch with i3 wm using an intel i5 8300h and a nvidia 1050 mobile.

I want to get back into sim racing and I'm looking for a new wheel. I used to do a lot of simracing on Windows with my old G27, but the FFB motors on that are busted and I decided to just get a new wheel. I can get a decent deal on G29 Driving Force (here). Does anyone have experience with this wheel on Linux? Does it work well? Would I need to do any tinkering to get it working? I'd like to use the shifter too, but it's not a must if it's problematic.

I used to play a lot of Assetto Corsa (which I see on ProtonDB that should work well) + I'd like to use it for Euro/American truck too (which I already play with a controller, so I know that there's no problem there). I'd also like to try AC Competizione, that one wasn't out in my simracing days yet.

I'm using Manjaro with kernel 6.17.8, in case it's important.

Any info or experience is appreciated, thanks.

Hello everyone! My project is a local server-based anti-cheat system for Linux. It's completely free software. If you want it for Windows, you can convert it to an .exe yourself with Pyinstaller. I didn't do this because Pyinstaller doesn't produce Windows .exes in the Linux environment. That's why it's only available for Linux. Here's my project's GitHub page:Hello everyone!

What would you recommend for gaming on Linux? I'm currently experiencing some issues with this. Firstly, my Steam client loads, but does not open at all if I launch it through a shortcut; it only launches normally through the console. Secondly, every time the system starts, Steam "forgets the disks" on which the games were installed, and I have to select them again. Thirdly, I am very concerned about the pre-caching of shaders, it takes a long time and loads my processor to critical temperatures. I use Proton Experimental for four and I am running into some issues: A couple of times when launching games I got a crash that forced me to reboot the system, and also during some games the load distribution is very strange - the video card is always loaded to the limit, and I need to somehow learn to limit it, but when I made the frame rate limitation through the launch parameters with the command DXVK_FRAME_RATE=75 %command% This limited my frame rate, but did not reduce the load on the PC, and after a couple of days this launch option stopped working altogether. I currently have Ubuntu and I'm planning to switch to Arch. Please help

Hello,

When I open steam, the window to load the user data pops up, disappears, and then the main Steam page never pops up. When viewing my applications (windows key), I see it pop up briefly as an invisible window, close, and open again, repeating the process forever.

When I run it from the terminal, it opens, but games won't launch. Everytime I click play, it starts launching, and then stops and the play button appears again.

It seems my issue is identical to https://www.reddit.com/r/Ubuntu/comments/1577jej/steam_games_refusing_to_launch/, however, there is not a solution on there for me that has worked.

I'm not entirely sure what I've tried at this point, I've done so many things that my brain's getting foggy. I installed my GPU drivers when I installed Ubuntu (from AMD's website), I'm not sure if they're working or not, but I can't find a clear answer on how to see if those are causing my issues.

I've also been having consistent issues with installing dependencies, for example when trying sudo apt install steam it would tell me that I had missing dependencies, so I installed them, yet it claimed that they're still missing. I had to go and download the deb file for one of them to get it to work. I can't find a clear reason why this is happening either.

Dear all

Apologies if this is not the correct place for this question.

I have Linux/Windows dual boot on my laptop, and I am considering to try Linux on my Windows desktop as well because I am frequently unhappy with Windows. I'd like to try and dual boot on this system as well, temporarily, and perhaps move to Linux permanently if everything works as I want.

My PC has a small windows SSD, a storage SSD and a HDD all used by Windows now. I was thinking it'd be easiest to use the many deals now to buy an M.2 SSD since my motherboard Gigabyte B550M DS3H has two unused slots now and install a Linux distribution on that.

I am a beginner in Linux and I'd like advice on three matters.

1) I checked the Gigabyte manual and found WD Black SN770 a good compatible M.2 SSD. I had thought of going for a 1GB or 2GB drive, for the whole Linux system as it were, but I have read that people recommend installing the Linux distro on a different drive from the storage drive. This would complicate matters for me as 1) I'd like to keep the other Windows drives as is for now and 2) I don't understand if my CPU 5600X has enough PCI lanes to support two M.2 drives, the GPU etc. Is it really necessary to separate the Linux OS installation from the storage?

2) My plan would be to install the M.2 drive in the motherboard, check if it is recognized by the BIOS and then install a Linux distro through USB on that new drive. Is that the correct procedure to achieve dual boot? I have read people recommend to 'disconnect' other drives and the like during the installation of a new OS, because of OS 'partitions' and the like. What are good practices for installing Linux in a dual boot setting when Windows already occupies other drives?

3) A small thing. For the BF6 beta I went through the procedure of enabling 'secure' boot. The beta didn't convince me and I have no intention of playing that game. I suppose I should disable this again before I start this procedure?

Thank you very much for your advice.

so i recently downloaded zorin os on my pc and deleted windows and both minecraft and roblox are 99% slower, minecraft used to get 300-400 fps in windows now in linux it gets 2-3 fps
