Hi, hoping to get some advice and that someone else has had some problem like this and can offer a solution.

System Specs: Ubuntu 24.04. on a system76 laptop with an AMD Ryzeb 7 7735U with Radeon Graphics × 16

The problem: Trying to play most games results in the game running horribly slow and my CPU usage jumping to ~100%. This doesn't seem to be a temporary problem (like if the shader's were being cached), I've left games running for 30+ minutes with the problem unresolved. Some games (this has specifically only happened with Deadlock and TF2) won't open at all. Games without any 3d graphics (specifically I've noticed this with RPGMaker games) still seem to run fine. This occurs for both steam games and at least 1 linux native game (factorio).

Background: I've been gaming with Linux for about 2 years and have never had an issue like this before. For the past two days trying to run practically any game results in my CPU throttling to max and the game running extremely slowly. This all occurred after I was trying to get an RPGMaker game to work, and in the process of getting it to work I ended up manually adding dxvk to wine and installing Lutris to get it to work. I'm not actually sure if that's the root cause of this, but I can't think of anything that has changed to cause this issue since I didn't have any system updates or other changes since the last time my system worked. I ended up completely uninstalling+reinstalling wine and completely uninstalling lutris which didn't help. I had originally thought that the problem was confined to steam/proton and completely uninstalled and reinstalled steam (and this is including deleting all files in .steam/ and .local/share/Steam and reinstalling games), which didn't fix the issue, and after testing with factorio I found that the problem wasn't unique to steam anyways. In terms of caching shaders the steam console output seems to suggest that that's happening (I'll post a screenshot in the comments), but even after leaving games open for 30+ minutes it remains laggy and the CPU remains at ~100%. So, I suspect I've done something stupid and somehow disabled dxvk or something, but I can't find anything to fix this.

Attempts to Fix: Completely uninstall/reinstall wine and steam. Updated mesa and also tried switching to the kisak/turtle release. Completely uninstalled lutris and also any packages installed with lutris. For steam games I've tried launching with several different proton versions (experiment/v10/v9) (I've also tried a handful of settings when using proton but I don't recall everything I tried).

I've downloaded the mod from here:

https://www.moddb.com/mods/quake-3-arena-rtx-remix-mod

I added the game to Steam as a non Steam game, enabled Proton Experimental, added the pak0.pk3 to pak8.pk3 files into the baseq3 folder, the game launches and runs perfectly but there's no RTX effects - it's just normal textures.

Has anyone managed to get this working under Linux with RTX effects? Video below:

Hey i used to use arch linux around 6 month ago, i have a laptop with igpu + rtx gpu using Nvidia optimus, i ran dx11 or vulkan games just fine, but i had a lot of performance issues with dx12 games, and yes i did setup optimus so that im using the rtx card while gaming, and i tried using proton / wine both gave same results, anyone have an idea why Nvidia gpus suck with dx12 games on linux? And is there a fix?

What was the last Linux native games you bought and would you recommend it?

I used Linux on and off since 2014, and changed to primarily using Linux around 2019. I wishi could get rid of windows, but games never worked well.

I remember ripping my hair out trying to get games to work on Pop OS. It was possible but too tedious. Performance issues, updates borking everything. Gave up, and switching to dual booting. Changed to arch a bit later.

But dual booting is frustrating. Needing to close everything and reboot to play games, having different settings and UIs sucks.

Gave it a try again last week, and holy fuck. It just works, especially with steam. EA and Epic were a bit finnicky but still, it works. Better performance than native Windows. Never going back.

Some anticheats don't work, but fuck those games. I'll play the ones which do, and it's not like there's a shortage of games that work perfectly.

Thanks, lord Gaben

I am running NixOS with niri and overwatch performance is way worse on linux when compared to windows. On windows I'm getting around 340-400 fps in practice range and never falling below 240 fps while in game with other players. While on linux I am getting around 250-280 fps in practice range on top of that it drops to around 110 fps in game. I expect some hit to performance because proton is translating my windows api calls but is this performance expected? I have enabled ntsync which did not help much with performance either tried setting shader cache location to ~/.cache/overwatch and increasing shader cache by setting environment variables in launch options. The game is installed on ssd with a btrfs partition. I have confirmed the game is running on Nvidia gpu as well.
Any help would be appreciated.

Some specs that might be relevant can provide other info if needed
OS: NixOS 26.05 (unstable)
Kernel: 6.19.6
DE: Niri 25.11 + noctalia
System: Lenovo Legion 5 Pro 16ARH7H
CPU: Ryzen 7 6800H
GPU: Nvidia 3070 Ti
RAM: 16GB

Edit: Kernel Version was wrong

For context, there's been a bug since 2013 where your screen would sleep mid-game because controllers didn't count as activity. The workaround was to use custom scripts, or third-party programs that you'd have to open/close every time you play a game. Now, I can finally re-enable my lock screen.

Using a legion go, so power isn't a major concern, but what's the best Dreamcast emulator? If it has a handheld/big picture UI or RetroArch core that's a bonus but not a need.

I am quite new to linux. Is gpu screen recorder VAC safe?

And in general, how can I determine if a program modifies game DLLs?

Thanks in advance.
