Has anyone run Marathon? I've tried it with Proton Experimental and Proton 9 without success on Fedora 43

Greetings!

After grappling with extremely jarring frame drops and stuttering, and multiple days of troubleshooting - I have conclusively fixed this issue on my AMD RX 9070.

Setup:

CachyOS Linux / Kernel 7.0 RC

AMD R7 5800X

Gigabyte B550 mATX

16Gb DDR4

750W Corsair (Platinum) PSU

Problems/Symptoms:

- Major frame drops and stuttering

- Intense power throttling visible in Mangohud (yellow line)

- Frame drops in Mangohud (green line)

- The higher the load placed on the GPU and the more power required, the more stuttering manifests.

- In Mangohud this is depicted as the green framerate line "bifurcating" or separating from the yellow power throttling line.

Instructions / Diagnostic / Power Management Tools Used:

- Mangohud and GOverlay

- https://wiki.archlinux.org/title/AMDGPU "It is required to unlock access to adjust clocks and voltages in sysfs by appending the Kernel parameter amdgpu.ppfeaturemask=0xffffffff.

- LACT for increasing power limit and enabling power states ("Power Usage Limit" slider maxed, "Performance Level" set to Manual, "Power Profile Mode" set to 3D_FULL_SCREEN. "Power States" checkbox ticked, "Enable Power State Configuration". A small GPU voltage offset is optional here but often benefits 9070's/XTs e.g. -50.

- Steam Launch Parameters: LD_PRELOAD="" PROTON_FSR4_UPGRADE=1 VKD3D_CONFIG=no_upload_hvv PROTON_USE_NTSYNC=1 RADV_PERFTEST=gpl mangohud game-performance %command%

Context / Write-Up

This is extremely difficult to troubleshoot as the symptoms have multiple causes that manifest in similar ways.

Initially I thought this was VRAM stuttering i.e the GPU running out of memory, the reason I thought this was because I found when I lowered the graphical settings far enough - especially Resolution / Textures / Details and elements that affect VRAM in particular, the problem seemed to resolve itself.

Needless to say, a 9070 should be capable of better performance than 1440p on low settings!

After discovering that lowering memory-intensive settings helped, I initially assumed I was running out of memory - which is insane on a 16 gigabyte GPU.

Then I noticed the power throttling and the low/unstable GPU usage, wavering around the 50%-80% range, lower than expected clocks and - this is key - the fact that the yellow frametime line in Mangohud would separate out from the green frametime line as soon as my graphical settings pushed / asked too much from my GPU.

Installing LACT was the key to fixing this. See the settings in the instructions above.

See the screenshot for proof of absolutely rock solid 100% GPU usage, locked in perfectly.

Conclusion

Power throttling / power limits manifest some very difficult-to-diagnose problems in Space Marine 2, and what muddies the water further, is the fact that this game itself chews through a lot of VRAM at high resolutions and when searching for solutions, one will come across a cornucopia of "fixes" that range from disabling SMT to deleting shader caches, to wiping your OS and so forth.

The power throttling also happens to MIMIC the symptoms of running out of VRAM for reasons I don't pretend to understand, making diagnosing it even more difficult.

After testing in game on all settings maxed out, with and without FSR Framegen - no more power throttling is in evidence and gameplay is extremely smooth, even at 4K - which is, as stated above, where VRAM limitations seemed to have been coming into play, while in actual fact it was the increased power requirements aggravating the stuttering / juddering and general poor running of the game. The multitude of complex optional Steam launch parameters only added to the confusion.

In closing, one has to wonder how many AMD GPUs on Linux are RMA'd for mysterious poor performance, especially on Linux where power/performance settings can be rather opaque, when in actual fact there is a mixture of throttling and (depending on the game) insufficient VRAM - which does indeed cause legitimate stuttering under the right circumstances e.g. an 8gb GPU running at 4K / Ultra graphics etc.

I hope this helps someone and am very keen to get feedback and answer questions.

Thank you for reading.

System info:

• OS: NixOS
• WM: Hyprland 0.53.1
• GPU: Nvidia GTX 1050 Ti
• Game: Deadlock (native Linux)
• Monitor: Samsung S24F350 — 1920x1080 @ 60Hz

What I've already tried:

• render:direct_scanout = 1 — minor improvement but gap remained
• general:allow_tearing = true — no effect
• decoration:blur:enabled = false — no effect
• windowrulev2 = immediate — made FPS worse in both modes
• cursor:no_hardware_cursors = false — no effect
• Gamescope — breaks Deadlock entirely (native Linux game, seems to conflict with SDL_VIDEODRIVER=wayland)

Ive been scrolling threads and its hard to nail down a comment that suggests a distro that will be optimal for what Im looking for.

I have my old gaming rig, (i5 4690K stable OC, gigabyte OC 1070 Gpu, 32 GB RAM). its currently running Win10 but the update bloat is killing it. Id like to back to a few games I loved like SPTarkov/modded Fallout4/Skyrim/Doom Eternal/Witcher 3. I was going to just do a fresh install of Win10 to try and get some performance back but with SteamOS and the momentum behind Linux right now I was curious if I could squeeze better performance out of a linux distro or maybe the SteamOS option. Last time I tried Linux it was a Ubuntu version back in like 2014. I just want to mod F4 and finish the DLC of Witcher 3 i never got to for the most part. While i mostly did 90-100fps in F4 boston downtown destroyed that. Ive seen some posts saying they did better with Fallout 4 on Linux.

I am trying to install nvidia drivers. nvidia-580xx-dkms - this is the driver that I installed, and also linux-headers too, but after i reboot and try to open , it stuck on cursor after the splash screen, Ans the above picture is tty information that I gathered

I’ve been trying to try some new mods for Cyberpunk 2077 and FNV - as I previously held a small collection of mods (< 20 mods or so) - which was simple enough to manage manually. However, I’ve been wanting to try some of the collections from Nexus, and have hit a bit of a snug.

I’ve tried installing the following packages from AUR:

- nexusmods-app-bin

- vortex

Both can handle NXM URLs and collections thankfully - given their native installations being used. While Nexus Mods App was easier to download and install the mods with, it doesn’t support FNV and would not properly install all of the core dependencies from the collection (Welcome to Night City v2.31a), leaving the game a broken mess and launching in safe mode.

Vortex on the other hand is an utter mess. They killed Nexus Mods App and replaced it with Vortex (again) but made it so that it’s Linux only. The AUR package solves the issue, but it fails to recognize game folders and versions. I tried defining my Cyberpunk 2077 folder, which is under `~/.local/share/Steam/steamapps/common/Cyberpunk 2077/`but Vortex kept throwing "This directory doesn't appear to contain the game. Usually, you need to select the top-level game directory, containing the following files: bin/x64/Cyberpunk2077.exe"

Exiting the window still defined the game by the looks of it, but trying to add a collection throws an error regarding "version mismatch". Not to mention, when I tried installing some of the mods from the same collection on a fresh folder, Vortex would fail to properly unzip some of them (`7z’, `unzip` and `unarchiver` are installed) where I’d end up with filenames such as `bin\x64\plugins\cyber_engine_tweaks.asi` in my root Cyberpunk 2077 folder.

I did try installing Vortex to my Proton prefix using Protontricks - which worked well it started panicking about the hardlink etc. way of staging/installing mods, and handing NXM URLs - where because it’s running in Wine/Proton, Firefox/Zen would not redirect the download to it.

Does anyone have any recommendations or proper way of managing modding on Linux?

Does anyone have any advice on how to take my game and files(including mods, game saves, etc) from windows to linux? I used bottles to install the game that I would be running. Runs fine but I do not see that saved files.

The Harbour Masters team recently released a big upgrade for SpaghettiKart, their Mario Kart 64 fan-made PC port with a bunch of new features.

Hi can anyone please suggest a linux distro for my old gaming laptop it has an i7-7700HQ and gtx1050.

I looked at bazzite but they dont support nvidia 10xx series yet for steam gaming.

Anyone has any other suggestions?? Thanks
