I have a 6700XT Nobara PC hooked up to a 4k 144 Hz TV (TCL C61K) via direct HDMI. I always assumed it was not 4:4:4 due to bandwidth limitations on AMD GPUs, but after doing some tests it seems like it is actually 4:4:4? For reference I am on the Nobara 6.19.10-200 kernel.

In the KDE session, HDR is enabled with 10bpc, resolution is set to 4k, refresh rate to 120 Hz with VRR enabled. If I go to https://testufo.com/chroma with 100% scaling, both visual tests seem to suggest it's 4:4:4.

$ kscreen-doctor -o
3840x2160@120.00*
HDR: enabled
Wide Color Gamut: enabled
Color resolution: automatic (10), range: [8; 16] bits per color
RgbRange: Automatic

$ drm_info
"max bpc": range [8, 16] = 10
"Colorspace": enum {Default, BT709_YCC, opRGB, BT2020_RGB, BT2020_YCC} = BT2020_RGB

$ xrandr --verbose
3840x2160 (0x41) 1498.250MHz -HSync +VSync *current +preferred

So does this suggest HDMI 2.1 is somehow working for me to some capacity? I haven't seen much news about this though so I'm not sure why it would suddenly work.

However for some reason I can't get 4k 144 Hz to work even though it's enabled in the TV settings. The 144 Hz option just doesn't appear in the plasma display settings even though the capability is there in the EDID metadata.

Hey everyone!

I just bought the game during the sale and while it's been running well performance-wise, I've been experiencing a lot of crashes during cutscenes, after about an hour or two of gameplay.

I have tried using multiple Proton versions:

• Experimental and proton-cachyos-10.0-20260320 crashed still
• GE-Proton10-34 caused a full BSOD:

QR that appeared on the BSOD

I checked ProtonDB where the game is rated Platinum, and there doesn't seem to be any sign of this being a widespread issue. Here's my system info:

I have not had any similar issues with any other game, including the two previous games in the series.

NiriWM is a Tiling Windowing Manager, https://github.com/niri-wm/niri
Ive been using it for the past 6-8 months and Ive enjoyed it, in terms of productivity it actually really helps me. Due to me able to switch from workspace to workspace, but in terms of Gaming, *IN SOME INSTANCES* it is buggy!
Examples with Black Ops 3 my games display freezes but the game is still working, and its just frozen on one frame but I can move and shoot (I can hear the sounds), same thing with Ultrakill and Battlefield 4, It happens at random. A fix I found was just to use Gamescope.
But some games like Overwatch and TF2 the game runs perfectly with no problems without gamescope.

Is gaming on Hyprland better or is it also buggy sometimes?

OS: Linux Mint Cinnamon
Proton: GE-Proton7-13
Game Version: Latest

Solutions Tested & Failed:
-Sudo update & Upgrade
-Removal of All Mods
-Restarting Computer
-Changing Proton to experimental
-Verifying Cache
-Reinstallation
-Punching a hole in a wall

TLDR: Game is basically unplayable

Long Version: I have no idea why this is happening, Benchmark is showing over 90FPS consistantly, but it seems like despite my desktop and monitor being set to 144, the game itself seems to be changing the refresh rate, I made sure there was no frame generation on, no raytracing, so what the fuck is the deal? Yall I'm honestly baffled, I was promised that it would "just work" with proton, and after many MANY hours, I'm furious. Somebody please explain what is going on and how to fix it.

Hi! Recently I got a new laptop with Linux (lux bellatrix, which from what I gather is a debian variant working on gnome?) because in my country it was significantly cheaper than getting the same model of laptop with windows, and I have been attempting to play games (which were obtained through completely legal manners, of course) through Lutris.

I have been using the same install files for these games (which were obtained through completely legal manners, of course) and they worked fine on Windows, are, in theory, working fine on linux — I can open, the game does not stutter or crash, and they play very well. It is not an issue of the game files being bad

However, with the specific game of Crusader Kings 2, I am having an issue that the game does not activate the mods despite reading the mods as being installed and active, and, when I play vanilla and save the game, it does create the savefile on its folder, both quicksaves and "hard saves" as I believe extra, separate files are called in english, but when I boot up the game again, it insists it cannot find any saves.

I need to keep the Lux Bellatrix for insurance and tech repair purposes, so I can't use the suggestion a friend had of "just switch to mint man", and most my friends use windows + steam, and the ones that dont use windows also use steam. From what I know of computers, this may be a question of the way files are ordered on linux through lutris messing with a game intended to be played through steam. How to fix this, however, or if it even is the correct diagnosis, I have no clue.

Help a poor fellow out?

My PC specs: I3 12100F, RX 9060 XT 16 GB, 16 GB DDR4 3200 mhz

OS: linux mint 22.2

I am trying to achieve 60 fps but game constantly drops to 30-50 fps range.

Proton: steam's proton experimental

Mesa: 26.0.3

I know my CPU is kinda weak (4 cores) but usually if it can't handle a game, it caps to a certain fps, when my character stops, I have constant 60 fps, but when I start to walk (move my character) the stutters begin

I made a tiny wrapper for Roblox on Linux because Sober is an android emulator, and the android roblox version has way worse graphics. That's why i created VineShade.

I put together a quick launcher that hooks vkBasalt into the Flatpak properly.

It’s open source, no injection, no bans.

Repo:https://github.com/olaffx/VineShade

I would really want you to star the repo!

Hey, I'm a Linux noob; I've only used Debian for a media server.

I want to find an OS for an older PC that has a Ryzen 3 1200 and a 1050ti. I plan to use it for lightweight couch gaming, emulation, media streaming, and game streaming from my main PC.

I'd like to not have to use a keyboard as much as possible. Is there any good OS for this?

I used to connect to ESO to play with my friends while in Windows. Now, under Kubuntu I was testing it and with the mesa NVIDIA drivers it played choppy and low res. So, with another gaming session coming, I went through the drivers tool and got myself a slightly older NVIDIA driver, that had one magic word attached to it. It said "tested".

Yesterday, I was able to play for hours in high definition, enjoying the time with my friends. One problem less, let's fix the next one.

I'm coming back to pc gaming after strictly playing console for a long time. To give you some perspective, the last time I was serious about pc gaming, I was playing CS 1.5 and DOD then maining WOW pre-BC.

I am now at a place where I am able to afford to revisit some of my old hobbies but pc gaming is completely unrecognizable. I don't even know where to start when it comes to hardware/software optimization. Having been subscribed to this subreddit for a while, it's become painfully apparent that there's a huge knowledge gap on the underlying tech, let alone how best to implement it.

I've been switched over to strictly Linux for a bit over a year now. As such, I figured this subreddit would be the best place to ask about relevant suggestions for resources and/or guides on how and more importantly what to learn.

I'm starting out with old hardware that I was able to source for cheap and upgrading as I go. Obviously with RAMpocalypse ongoing, I've been a bit hesitant to invest in a full-on gaming rig at this time. I'm aware that my cpu is dated and low power and am also aware that I'm losing performance with an egpu setup. The goal is to eventually move away from both. I'm more interested in what tweaks and tech exists now to really get the most out of pc gaming vs console.

Sorry for being so long-winded. I'm just hoping someone is able to translate my idiot post into something useful! If I'm in the wrong spot, feel free to let me know.

Potentially relevant system info:

Distros- cachy/mint

PC- Dell Optiplex 9070

CPU- Intel core i5 9500t

RAM- 32GB DDR4

Storage- Kingspec 2TB Sata 3 SSD, 22TB HDD RAID

EGPU- ASRock steel legend 9060 XT 16GB (running via m2 adapter)

Hello! :)

I bought a new laptop with a 275HX and 5070M yesterday and I soon realized that VKD3D is not ready for the Blackwell series, at least on laptops. Proton CachyOS with PROTON_VKD3D_HEAP=1 improves things but still many games don't even launch or just freeze at some point (Final Fantasy XVI and the Black Myth Wukong Benchmark come to mind).

Worse of all though is that VRAM usage is absurdly high and doesn't get freed with time. Final Fantasy VII Rebirth s literally unplayable on the very lowest settings after some minutes cause VRAM gets filled up, something that doesn't happen with everything maxed out in 4K on Windows which pumps out 150+ FPS with 4x FG on. Also, with FG enabled there's image trembling which also doesn't happen on Windows.

Is there any remedy for all these issues until the Heap extension is finalized or should I just boot into Windows for gaming (apart from Cyberpunk which seems to perform substantially better on Linux for some reason).

so we all know the situation with anti-cheats on linux - most dont work, faceit has no native client, vac barely does anything

been working on this thing, its a daemon that uses ebpf and /proc scanning to check if someone is cheating. has a server with trust scores and matchmaking too

not trying to replace vac or eac, more for community servers and tournaments where people want clean games on linux

still early, v0.3. would be cool to hear what you guys think
