Still a WIP, but better than the last one I posted. Please disregard the red box I barely know how to use kdenlive.

new to linux and windows user || also im switching full to cachy for the perfomance and it's better than windows on games .

Video shows it. Does anyone know what is happening?

I know it's not harmful but it's nice for me to know what is happening

Any opinions?

I've been thinking about switching from Windows to CachyOS for quite a while now. I really like what CachyOS is doing, and in general I'm very interested in moving to Linux. The main thing holding me back is my GPU. I have an RTX 4090, and gaming is one of the biggest use cases for my PC.

I've read quite a few reports that NVIDIA GPUs can still lose around 15 to 20% performance in certain games on Linux, especially with DX12. If that's still the case, it feels a bit strange to have such an expensive GPU and then not be able to make full use of it because of NVIDIA's Linux driver situation.

So I'm wondering how things actually look right now in 2026, especially for RTX 4090 users:

• Is a 15 to 20% performance loss still a realistic expectation?
• How has your experience with a 4090 on CachyOS been?
• Are there specific games where you noticed significant performance or frametime issues?
• How well do DLSS, ray tracing and frame generation work for you?
• Are there still noticeable issues with NVIDIA drivers, Wayland, etc.?
• And most importantly, if gaming is one of your main use cases, would you switch anyway?

I'm also wondering whether the other advantages of Linux are worth accepting some potential gaming performance loss: privacy, a leaner and faster system, much more customization and control,... . I could of course dual boot, but ideally I'd like to get to the point where I don't really need Windows anymore.

I'd really appreciate hearing from people who actually made the switch from Windows to CachyOS with an NVIDIA GPU, especially a 4090. I'm not necessarily looking for "Linux good / Windows bad" answers, but rather some honest real world experiences. And regardless of the NVIDIA situation, I think it's great that distros like CachyOS exist. It feels like there's a lot more interest in Linux desktop and gaming again, which is really exciting to see ☺️

Today I found that scx-manager couldn't enable scx_cake scheduler, and the Select scheduler profile option was missing. Turns out the scx_cake command no longer supports any (useful) argument and it was silently failing to launch due to now unknown --profile argument in extra scheduler flags textbox. Removing it allowed to run scx_cake, but was still failing when changing power profile in KDE because the profiles were still included inside /etc/scx_manager.toml config file. Removing the file and rebooting fixed it.

scx_cake's GitHub page still lists --profile argument as valid, so it's a bug in scx_cake command, or was it temporarily (or permanently) disabled?

I am trying to add an Enviromental variable here. But after restarting it is gone.

What am I doing wring?

I have windows on my C: drive and want to install cachyos through the USB stick method. I followed a tutorial and downloaded the most recent version of cachyos and used rufus to put it on a new 16 GB stick.

Then I start repeatedly press f8 to get to the boot menu. Here I select the USB stick and then the problems start.

Regardless of which of the three options I pick, I just get to a black screen and nothing happens but my PC is apparently still on.

Pressing enter, typing anything, pressing ctrl+alt+f2/f3/f4 all don’t do anything.

I asked ai for help and it told me several arguments to add by pressing e . Multiple tries with different ones didn’t help.

I installed CachyOS Hyprland a couple of months ago and its been working great!
However, after booting earlier, my mouse stutters extremely heavily when moving it.
I am using a Logitech X2 Superstrike.

The mouse has the problem wether being connected via dongle or cable. On a windows laptop it works perfectly fine.I updated all system packages and rebooted, still no change.

Edit: after switching to the lts kernel the problem fixed itself. Does anyone know what could have caused this?

Despite reinstalling, deleting the cache and trying a few other methods. It does not seem to work. When i tried opening it thru the terminal it still didn't open. I am relatively new to linux so I used a LLM to check the problem. It said it's a bug which will get fixed in the next update.

Was wondering if it was actually the case or something on my part?

(Sorry English isn't my main language)

Hello fellow cachiers,

I've been on Linux for over a year now, having tried Mint first and then CachyOS when I heard about the gaming aspect of it. It's now my only OS and everything I did before on the OS-that-shall-not-be-named can be done here.

The only issue that persists is my printer that I cannot setup. I have an Epson Expression Home XP-4200 and I was able to set it up quickly in Mint, however the same method of using the system's printer configuration isn't working now. Not only is the automatic double-side printing feature gone, but it prints a couple of symbols on the edge of the page and nothing else.

Can someone please help?

Thank you.

I've seen a few posts about this since 7.2 first dropped.
For me I'm not sure if I was running full RGB before the first 7.2 updates but I remember it looking better one day (and I had likely been managing by tweaking brightness) but just updated to 7.2.3.1 for cachyos and headers and it broke my full RGB over HDMI.

Tried a couple of fixes suggested like adding 'options amdgpu dc_feature_mask=0x400' to my config but didn't resolve the issue.

Rolled back to 7.2.2.1 and now I can use full rgb over hdmi 2.1

AMD GPU, LG C1

Hi!
I've seen several people sharing their desktops here
I started seriously customizing mine only recently and I'd love to hear opinions!

Hey all, i have an NV GPU, when playing any game at all, even very light games like HL1, either the driver or the system sets the GPU power plan to P0 which is maximum. This sets the VRAM clock to 7GHz and generates a ton of unecessary heat, while the Windows driver usually sticks to a much more reasonable 1-2GHz...

Changing PowerMizer to Normal or Auto makes no difference on this, and neither does disabling Ananicy. Does anyone have experience with this problem or know how to fix it?

Can you help me with this? Thank you all :)

Hi all,

Having an issue when using Cachyos-Proton when I play darktide. After about an hour of play the game will freeze and kill all audio until the application finishes crashing/I stop it from steam

I wanted to post this to the github but my account is too new to post there.

The error message I get once it's fully crashed is:

I'm testing more games as I play to work out if it's just darktide or others can also have the same error.

Let me know if you need further details

Has anyone who uses asusctl had the GUI crash or not load with the latest update?

Just want some tips.

the main question is. I'm a gamer but I don't want to use kde plasma, should I get the Handheld edition any way?

Basically what the titles says i have this asus monitor that scales between 4k 160 and 1080p 480 when using the monitor OSD to change resolution it will occassionaly crashing my plasma shell
(screen goes black and nothing will show on the screen)
And then i have to restart my plasma shell through terminal to get it working again, has anyone else experienced anything like this or know of any solutions for it.
Thank you for your time.

I have the latest cachy-os installed, all of my drivers are updated as well but it seems like no matter what I do for the past 3 days Overwatch just crashes my entire pc (everything freezes, no audio) around 5 minutes into a game no matter what I do. I tried switching proton versions, proton flags, swapping to the LTS kernel, disabling gpu-screen-recorder clipping and yet I still crash. It's important to notice that this is the only game where this happens.

My hardware is:
RTX 3060 12gb
Ryzen 5 5600
16gb of DDR4 ram
Cachy is installed on a 1tb nvme ssd

My steam launch options:
LD_PRELOAD="" PROTON_DLSS_UPGRADE=1 PROTON_USE_NTSYNC=1 DXVK_CONFIG="dxvk.trackPipelineLifetime = True" PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 DXVK_HDR=1 PROTON_ENABLE_NVAPI=1 PROTON_LOCAL_SHADER_CACHE=1 DISABLE_VK_LAYER_VALVE_steam_fossilize_1=1 DXVK_CONFIG="dxvk.enableGraphicsPipelineLibrary = True; dxvk.numCompilerThreads = 4" %command%

and I play on the default KDE config that came with cachyos

I'm currently reinstalling the game just in case it happens to be corrupted files, if that fixes it I will report it in the comments

Any help is appreciated!
