VALVE's Deadlock weird performance issue bug

Reddit Linux_Gaming - 23 Dec 2025 - 9:07am

Greetings!

For the past month, I've been running Fedora KDE Desktop (Fedora 43) on my PC, completely replacing my previous Windows installation.

I'm in love with the whole system and I haven't had any issues so far when it comes to gaming or the software I use in general.

Path of Exile 2, Baldur's Gate 3, Helldivers 2, everything runs great on smooth constant 60 FPS.

I keep having a weird issue when it comes to VALVE's Deadlock though. Granted, the game is still in Closed Alpha but for some reason, it seems like I am the only one who has this particular issue.

Before I get into the details of the issue though, my whole configuration is the following:

OS: Fedora Linux 43 (KDE Plasma Desktop Edition)
CPU: AMD Ryzen 5 5600G
GPU: AMD Radeon RX 6600
RAM: 2x4 DDR4 4GB + 1x1 DDR4 8GB @ 2666 MT/s (Single-Channel, can't go dual-channel atm)
MOBO: Gigabyte B450M DS3H V2
Compositor: Wayland

Steam is installed through the distribution packages, not through Flathub.

I'm running the game under Proton Experimental with the following Launch Paremeters:
PROTON_ENABLE_WAYLAND=1 RADV_PERFTEST="dccmsaa,gpl,sam,nircache,transfer_queue" %command% -vulkan -nojoy -high -threads 12 +fps_max 0

So, the issue I'm having is the following. One day I'm launching the game and everything runs just fine. GPU usage is at an almost constant 99% and VRAM usage sits at around 5.4GB/8.0GB and I'm easily maintaining 60 FPS and above.

The other day, I may launch the game and for the rest of the day, my console is being spammed by the following log: [SteamNetSockets] Waited 2.3ms for SteamNetworkingSockets lock [GetSessionConnectionInfo]

While that happens, I do notice that my GPU fluctuates betweeen 20, 60 and 80% GPU usage, never being used to it's full extent. FPS plummets during matches, dropping to below 40-30.

Changes to graphical options seem to have no effect when it comes to this issue.

I've tried multiple things:

  • I've set CPU's Frequency Governor from powersave to performance
  • I've set GPU's Performance Level through LACT to Highest Clocks
  • I've tried multiple Proton versions, even GE-Proton
  • I've tested multiple launch parameters, tried both DX11 and Vulkan
  • I've tried using X11 instead of Wayland
  • I've used gamemoderun launch option before %command%
  • I've used gamescope as well
  • I've tried setting the game's affinity to different set-up of cores/thread: 0-5, 1-6, 2-7
  • I've rebooted both the router and the PC (thinking it may be network related) and I've also disconnected the Ethernet table
  • Tried disabling fsync as well, no luck there either

Despite all these things that I've tried, the issue seems to persist. I do have Proton Logs both from the "bad launch" of the game, so to speak and from the good one where everything runs smoothly.

Unsure whether I should post them or not, since I do not know if there's any sensitive information in there.

Can anyone point me to some direction, something to check out or the potential culprit of this issue? It's literally the only game I'm having issues with in Linux so far. Every other game I've tried from my steam library, works just fine (aside from having to mess around a bit with DX11, DX12 and Vulkan).

I've done as much research on the whole thing before making this post but considering I haven't managed to figure anything out, well, here I am.

I'd appreciate any help if anyone is familiar with the whole topic.

Modding Fallout on Bazzite

Reddit Linux_Gaming - 23 Dec 2025 - 9:05am

I recently switched over to Bazzite after using windows my whole life and wanted to know if there was anyway I could continue modding game like I used to? (Admittedly I didn't research Bazzite and Linux as much as I should've). To my knowledge Vortex and Mo2 don't work under Linux and I couldn't find any alternatives. I was wondering if was still possible/accessible/easy to do.

Games i wanted to mod are: Fo3, FNV, Skyrim, and CP2077.

any help is welcome, thank you in advance

Weird screen distortion with Gamescope

Reddit Linux_Gaming - 23 Dec 2025 - 7:27am

I am using Linux Mint 22.2 x86_64 on an Intel computer. I was trying to play Metal Gear Rising with Proton when I noticed this weird bug where if an another window was focused and the game was focused back it would start flashing white. To fix this, I decided to compile Gamescope. The issue I intended to fix is resolved, however, for whatever reason the screen has these really bad distortion artifacts particularly in cutscenes. I tried vkcube and glxgears and the issue persists. I searched everywhere for a fix and even though there were other people who had screen artifacting with Gamescope I wasn't able to find anything that would help.

Weirdly, the issue only appears in fullscreen or on a borderless window without taskbar. And disappears when I take screenshots or on a window.

Pro 2 Back Buttons not being seen by Steam Linux

Reddit Linux_Gaming - 23 Dec 2025 - 7:13am
Issue

Not too long ago steam added direct support for 8bitdo controllers to Steam Input allowing their back buttons to be mapped without needing the ultimate software. I’ve recently moved over to Linux and have got my Pro 2 connected to my system. It’s being read as a pro 2, the home button icon has even changed to the 8bitdo logo as it had before on windows. But I can’t seem to find a way to get the system to recognise the back buttons. Has anyone had any this issue and resolved it?

Would there be any compatibility issues with racing pedals or should they be recognized fine?

Reddit Linux_Gaming - 23 Dec 2025 - 6:31am

I'm looking to upgrade my wheel and pedals soon, and while wheel compatibility is pretty well documented, I can't find anything on pedal compatibility. Does Linux just recognize all pedals as generic input devices or is there potential issues to avoid?

Best solution for trying Linux

Reddit Linux_Gaming - 23 Dec 2025 - 5:34am

I have a b650 across ax with a 2tb Gen 5 ssd. I know my mobo has a couple of Gen 4 ssd slots but from what I can tell none are easy to access without taking out my mobo entirely

I have not great fine moter skills so I'm trying to find the easiest way and in hindsight I'm kicking myself for not grabbing 2 ssds when I first had it built

My thoughts are to try an external ssd or to partition about 500gb from my current ssd.i have a 3.2x2 poet on my case and mobo

I don't play many multi-player games but I want to make sure I don't have any major issues before fully transiting from windows

Any thoughts?

Thanks

Elden ring getting 30fps or lower despite steam saying cpu/gpu are at 50% utilization

Reddit Linux_Gaming - 23 Dec 2025 - 5:31am

I have an ancient CPU (10 year old i7) which can often run into issues but eldenring is chugging a fair bit despite steam saying it's not even at half load for either. On windows I get roughly 60 with slight dips.

Latest ge proton, 10-27 I think. 390 nvidia driver, latest arch kernel with ncsync or whatever it's called enabled.

Weird Graphical Glitches on Marvel Rival, Help?

Reddit Linux_Gaming - 23 Dec 2025 - 5:26am

So this started when I updated to the newest version of Fedora 43. Suddenly there are these weird graphically glitches throughout the entire game where the HUD disappears(even midgame), shading on the characters is very dark but only on the menus. It doesn't impede the game at all but it does seem very odd to suddenly be occuring. Maybe an issue with the latest version of Mesa? Interestingly, I only see this occuring with Marvel Rivals. All my other games have no issues with these graphical glitches. If anyone has seen this and knows of a fix, that would be very helpful. Also, yes I have reloaded my shaders on Rivals and it persists

Specs: Intel 12900K, Intel Arc B580 LE, Fedora 43, mesa-25.2.7-3.fc43

G502X Wireless (No Right Click)

Reddit Linux_Gaming - 23 Dec 2025 - 5:01am

With all the jumps in linux gaming I recently jumped back to linux on my main rig. Normally I am on some debian based system but I was enthralled by all the cachyos hype. I have used some Arch based distros in the past and am not incapable of finding my way around. I am a bit stuck right now though. When testing my current daily game (Borderlands 4) I noticed that right click wasn't working to scope. Then I realized that right click wasn't working in the DE. I have libratbag and piper installed but piper only reports the Powerplay (Logitech Candy). I have played with Solaar a bit to look for issues. My G733 headset and G915 keyboard are working great. After trying several avenues I discovered the power switch on the bottom of the mouse will turn the mouse on and off, but will also trigger a right click. I can't find anyway to correct this mapping! Has anyone else experienced this? Search attempts have only been able to find different issues with right click glitches for the G502.
