my yah-har'd copy of elden ring has weird frame drops, and then speeds up, and then drops in frames again and it's messing up my game real bad.

i'm using an acer nitro 5 with an rtx 3060 and a ryzen series 5000, and am running the game through heroic on cachyos latest.

It even has a AppImage version. I hasn't tested it though.

Hi folks, I hope it's alright that I post this here because I have spent hours trying to figure this out. I thought I would post this information because others have had the same issue as me but there wasn't much advice on what to do and it turned out to be ridiculously simple. I am running the latest version of Linux Mint and installed MO2 for use with Skyrim SE.

When installing Mod Organizer 2, an error comes up that shuts down the whole process:

/tmp/mo2-linux-installer-downloads-cache/OpenJDK8U-jre_x64_windows_hotspot_8u312b07’: permission denied

I opened to my /tmp/ folder as admin and located the folder called 'mo2-linux-installer-downloads-cache' that MO2's installer had already created. If it doesn't exist, you can make one, just be sure that it is named correctly. I then changed the folder permissions from root to my user. When restarting the installer, MO2 was able to download to the folder and install correctly without the permission denied error.

Another issue that came up was a problem with WINE:

warning: Unknown file arch of /home/$USER/.cache/protontricks/proton/GE-Proton9-1/bin/wineserver

Updating Winetricks fixed this issue. You can update it with:

sudo winetricks --self-update

I found this fix here: https://github.com/Matoking/protontricks/issues/286

Hope someone finds this useful!

Which of these options do you consider superior based on your experience?

I'm interested in hearing opinions on aspects such as performance, compatibility, and long-term stability.

Thanks!

Hey boys and girls, I am wondering if Linux (or rather Nvidia drivers under Linux) support native G sync modules without having to use any software Vrr at all. I am looking to switch to Linux as im sick and tired of windows forcing Vsync and having to use hacks and workarounds to disable it when on Linux I can just turn off the compositor entirely and also have good core scheduling (disaster on win11). Thanks!

I understand that Nvidia support for Linux is lacking quite a bit but some of the issues I see people having with them seem..... Strange. I'm running 48gb DDR5, an i-7 13700F and a Zotac 4070Ti Trinity OC and I have almost no issues what so ever on CachyOS. Sure my max FPS is lower than it would be on windows but I get much more consistent frame rates and a much smoother gaming experience all together than windows ever gave me. I don't have issues with waking my PC from sleep either like I've seen some people talk about. I'm just curious why it seems like so many people have issues with Nvidia that most people will just recommend switching to AMD.

I'm not sure if OpenEmu is relevant anymore, but I used to use it on a Macbook I had years ago. I'm just looking to emulate a variety of retro games and I liked how that let you do that. Here is my rig:

Basically I dual boot and am using Heroic Launcher to launch City Skylines on the Nobara 42 Linux . I was wondering about the arguments section. I have tried the "-nolauncher" argument but nothing else. Is there a way other than yanking the PC apart for me to play (I also really hate Windows on a personal level) I will be back with a different post so 1 of 2 post for different problems

I used cachyos and bazzite for around 6 months, i've been happy with them and considered them a must have, but now after about 1 month of random kernel panics on Bazzite i was sure i had hardware issues since Bazzite is an immutable distro therefore no way i messed up something so bad that it crashes the computer, so i did a memtest86+ and left it running for 13 hours no errors at all.

So I opted to install something reliable like Fedora, after installing Steam and protonplus i was already setup for gaming wtf (im on AMD)? Games are running with same exact performance as before (i verified with benchmarks) except now my computer doesnt crash anymore.

I remember in the past when i used to mess with Android roms the very first thing you saw written in custom roms was "dont blame the developer if your clock app doesnt work and your morning alarm doesnt wake you for work"

Im sure the team behind Bazzite is very competent but why does everyone seem so eager with trusting them? They are still hobbysts messing around with the Kernel for negligible performance gains which are all within 5% margin of error compared to Fedora, i would more easily trust Fedora which is sponsored by red hat

Rust: meant 5070 ti in title

I have a 5070 Ti, 9800X3D, and game on a 240Hz ultrawide OLED with HDR.

My main games are Overwatch, Darktide, Warframe, Path of Exile.

My experience with Nvidia is currently fine, all games are working, but Darktide has noticeably worse performance than windows. Is it worth going the the hassle of swapping cards? Especially with the DX12 fix (likely) coming this year, and the recent announcement of GeForce experience (or Nvidia app, whatever) for Linux

So i decided to test the game on linux as we can pre download the game now, but Oh boy does the game not want to start

The launcher installes ok but the actuall executable does not want to start.

SO far I have tried:

* Proton Experimental

* Proton-GE latest

* Wine

and all of them failed

here are logs if anyone wanna debug them:

I have a 'big' workstation with an AMD cpu with mutiple CCDs and NPS4 so lots of NUMA nodes. While this is great for my typical workloads gaming has been less then amazing. Benchmarks seem fine but games like Cyberpunk 2077 are stuttey/frametime mess even at medium settings. What's really funny is even games like Age of Empires II while perfecly playable also had issues and after applying this script is now butter, I never would have known.

I got tired of manually messing with affinity settings, so I spent a couple of days vibe-coding a tool to automate the fix: gpu-numa-tune.

What it does:

It’s a straightforward utility that identifies which NUMA node your GPU is physically attached to and automatically sets the CPU and memory affinity for your game. The goal is to keep the game's execution "local" to the GPU to minimize latency and keep the frame delivery smooth.

Why I built it:

I wanted something simpler than maintaining a bunch of custom launch scripts for different games. It’s a project I put together quickly to solve the issue on my own rig, but I figured others in the community with high-core-count setups might find it useful too.

GitHub Link:https://github.com/mattkenn4545/gpu-numa-tune

Key Features

• Automatic Node Mapping: It identifies exactly which NUMA node your GPU is physically attached to.
• Zero-Config Tuning: Automatically sets CPU and memory affinity for the process so it stays on the "local" hardware node.
• Smart Process Filtering: Only PIDs that are using the GPU and children of game launchers (proton, steam etc...) will be effected.
• Persistent Service: Runs in the background as a systemd service to keep things optimized without manual intervention (or not, can be ran as a daemon or one-shot)
• Focus on 1% Lows: Specifically designed to reduce microstutters and stabilize frame delivery in latency-sensitive games.

How it Works

gpu-numa-tune optimizes performance by ensuring the entire execution path—from CPU instructions to memory access—stays on the same physical hardware node as your GPU.

• PCI Topology Discovery: The script queries the system's PCI bus (via /sys/bus/pci/devices/) to identify the specific NUMA node physically wired to your GPU’s PCIe slot.
• Process Filtering (fuser): Only proceses that are using a GPU are considered. Agnostic to GPU manufacture.
• Process Affinity (taskset): The background service monitors for active game processes. When detected, it uses taskset to bind the game’s entire thread group to the specific CPU cores belonging to the GPU's local NUMA node.
• Memory Locality (numactl): It enforces memory allocation policies using numactl, ensuring that the game’s data is stored in the RAM banks directly attached to that node.
• Memory page migration (migratepages): Attempts to migrate pages to the local numa node if possible.

Flexibility

• Dynamic Affinity Modes:
  • Gaming-Only Mode: Automatically detects when a game is launched (via Steam/Proton or standalone) and applies optimizations only to that process, leaving your background tasks untouched.
  • System-Wide Mode: Option to force all non-essential processes to secondary nodes, giving your game exclusive access to the GPU-local cores.
• Hyper-Threading (SMT) Control: Smart detection of logical vs. physical cores. You can choose to pin to physical cores only to reduce contention or leverage all threads for CPU-heavy titles.
• Node-Aware Memory Management: Beyond just CPU pinning, it enforces Memory Locality. You can toggle between "Preferred" (try local first) or "Bind" (strict local only) to prevent performance-killing remote memory access.
• Configurable Sleep Intervals: Fine-tune how often the background service checks for new processes, balancing responsiveness with low CPU overhead.
• Auto-Detection & Manual Override: While it’s designed to automatically find your GPU's node, you can manually specify nodes and core masks for complex or non-standard hardware layouts.

Quick How-To: Installing the Service

Setting it up is pretty straightforward. You just need to clone it and run the install script to get the service live:

1. Clone the repo: # git clone https://github.com/mattkenn4545/gpu-numa-tune.git, cd gpu-numa-tune
2. Run the installer/updater: # sudo ./install.sh
   1. Copies the script to /usr/local/bin
   2. Enables the service and starts

It’s still pretty new, but its made gaming on my system viable. Open to feedback and ideas!
