LSFG-vk dual GPU, how to setup properly?

Reddit Linux_Gaming - 8 Oct 2025 - 9:13am

Hi, I would like to use a Dual GPU setup but there is something I don t understand : how to setup properly.

I am new to this, even if it looks like the old 3dfx days

I am on Bazzite-nvidia flavor.

I have a dual screen setup but I only use one screen (primary) when playing with or without LSFGVK. secondary screen is for reading.

My main GPU is RTX 2070s. currently pluged into both monitors via Display port.

I am planning to buy an RTX 3050 6 Go for LSFG-VK frame generation. bonus question will it run at 3x without artefacts?

here is my trouble understanding how it works.

As I understand :

-When using the system WITHOUT lsfgvk enable (like normal 2d games or normal system usage) I must plug my main screen to the 2070s and secondary screen to the RTX 3050.

-When using the system with framegen turned ON the RTX 3050, I must plug my main screen to the 3050 and 2070s to the secondary screen?

There is something I am missing/ not understanding.

Higly unusable ? or using more displayport / hdmi cables to connect both cards on both displays?! ?

Please explain like I am five, I am new to using linux as my main machine, liking it !

Why can't wall-hacks be prevented by the server by withholding enemy player coordinates until they are supposed to become visible?

Reddit Linux_Gaming - 8 Oct 2025 - 6:12am

Take for example games like Fortnite / Apex Legends where the server is responsible for handling up to 100 players. Both of these games worked on linux at one point and technically the base games still do under proton. However, they are intentionally blocked on linux due being unable to enforce client-side kernel level anti-cheat protections.

In these games, all players update the game server with their current coordinates on the map. The server in-turn updates all clients with the coordinates of all other players on the map. The client's game then performs the logic on the client-side to determine which players should be visible and should be rendered onto the screen. Wall-hacks exploit the data from the server to also render players who would normally not be visible (such as those behind walls).

What is the reasoning behind why a server cannot withhold sending enemy player coordinates to the client until that enemy player is supposed to become visible? What are the implication of using this as a strategy to prevent wall-hacks?

I want to try another Linux distro

Reddit Linux_Gaming - 8 Oct 2025 - 5:08am

I have an old, low-spec laptop, I installed Endeavor OS because it's lightweight, but I want to know if there's a specific distro for gaming that works well on my laptop and I only plan to play Minecraft, Hollow Knight, or NFS MW. Which distro do you recommend to get the most out of it?

Preserving my Steam library when distro-hopping - do I have the right idea?

Reddit Linux_Gaming - 8 Oct 2025 - 4:57am

I'm currently using Bazzite, and I really like it. But I think I'm ready to try something a little more challenging, and I want to migrate to CachyOS. Importing my whole home folder seems impractical and unnecessary, everything I want to preserve can be easily backed up to a separate smaller disk... except my Steam games. So, I have an idea, and I want to put it out there before I just go and do it in case I'm missing something or neglected something important.

I'm thinking I should shrink down my current partition, I have plenty of free space left over to do it atm, and then create a new, temporary partition just to put my games on. (I'm not sure if making it a Steam library through the Storage settings menu is the right idea here or not.) Then, once I've installed CachyOS, I just drop the games into my fresh Steam install, nuke the temporary partition, and then expand CachyOS's to encompass all the free space.

This seems like a good, clean solution to me - but I'll freely admit I lack the knowledge and foresight to know if this is a good idea. I just don't want to redownload all my games again. What do you guys think?

Vulkan GPU Utilization

Reddit Linux_Gaming - 8 Oct 2025 - 4:35am

In games that use Vulkan they seem to refuse to use all of my GPU, I can max out settings, remove the frame caps and get around 60% utilization max with around 90w being the max power draw.

I tried another, albeit much less graphically intense game that runs in OpenGL and it was able to hit the max frame cap allowed by the game of 300fps and sit there with utilization increasing when needed. I am using feral gamemode, have tried changing the power profiles using ctrlcore and lact, set my KDE power state to performance and so far nothing has changed unless I play a game with OpenGL instead.

I have a 5800X CPU and a 7800XT GPU.

Overall help to play games??

Reddit Linux_Gaming - 8 Oct 2025 - 4:25am

Hello, I used Mint for about a month and have lots of previous coding experience so I said you know what let’s save some time and I skipped straight into Arch. Currently I’m running KDE plasma 6, newest version, and I’ve seen a very strong trend of —-> want to play game —-> watch guide —-> download runner (wine and proton more of a one time thing nonetheless) ——> eventually get to the point of it not working because the guide didn’t tell me I needed this 32bit system installed or this special proton release. In general I’ve installed all “base packages” (I hope and think) wine, proton, steams all set up, (currently stuck and fixing Ubisoft connect on lutris this is one example on not being told about certain needed things) and I’m hoping someone can tell me based from experience what drivers I will need to play popular games, what packages do I need? I’m pretty familiar with everything and I have multilib enabled so my repository isn’t limited I’ve installed everything, seems to be a constant issue for me around the corner and till I get enough money for another storage device I don’t want to dual boot on this one device, rather I want to dual boot separately on two devices one for each of them. (Because I don’t want to experiment any issues with time shift possibly wiping windows on my drive and other things). Sorry for the long paragraph maybe I’m not reading up on everything correctly, but steam works fine w/proton (I used proton-QT to update anything) but I’m struggling with Lutris.

Middle mouse button is partially unusable in a few titles through steam/proton

Reddit Linux_Gaming - 8 Oct 2025 - 2:50am

I have a bit of a weird one. Space engineers and satisfactory refuse to acknowledge that the middle mouse button is pressed while in game, but satisfactory is able to see the middle mouse button when binding controls. I am at a bit of a loss. For this, I'll just focus on the Satisfactory middle mouse since the test cycle is faster to start a game on that one.

I'm using wayland with %command% -vulcan and variations of things like SDL_VIDEODRIVER=x11 PROTON_USE_RAW_MOUSE=1 %command% and various other issues. The mouse is being found by rawinput (as seen in the proton logs).

I have tried with both proton experimental and proton GE (not entirely sure which version, but I can look it up if needed), but neither seems to change anything.

I'm wondering if anyone has any ideas or has seen anything similar. The game is still playable, but it's frustrating not being able to 'pick block'.

Thanks in advance!

Finding Non-Steam Save Files

Reddit Linux_Gaming - 8 Oct 2025 - 2:46am

Hey folks, I have a very specific problem, I live in south america so I often can't buy some games. So I normally torrent them and buy when there's a sale or something like that.

I have about 70 hours on Hades II, I loved the game so I made an effort to buy it when it was got fully released.
Problem is, I have no idea of how to transfer my old save file to the the game I downloaded legally on my steamapps folder. Anyone can help me figure this out?

XCOM long war 1.1?

Reddit Linux_Gaming - 8 Oct 2025 - 1:47am

is there anyone who got LW 1.1 working on Linux?

i know the original runs great on the native version of the game, but since 1.1 doesn't have a native port I don't know how to get it working.

the obvious way would be to run the game under proton, however the provided files and directories in 1.1 are named with different casing than what the game expects, so you either need to manually rename every single file or you can suck a fat one, since linux fs and basic copying operations are case sensitive

EDIT: there's an installer but it seems to break under wine

I made a CLI tool to control Elgato 4K X/S capture cards on Linux in Rust

Reddit Linux_Gaming - 8 Oct 2025 - 12:31am

Hey everyone!

I got tired of not being able to control my Elgato 4K X capture card on Linux (official software is Windows/macOS only), so I reverse-engineered the USB protocols and built a command-line tool to fix that problem with limited features.

What it does:

  • Toggle HDR tone mapping on/off
  • Fix color range issues (expand/shrink/auto) - super useful for PS5/Xbox
  • Control EDID source (display/merged/internal)
  • Enable/disable custom EDID (4K X only)

Supported devices:

  • Elgato 4K X (fully tested)
  • Elgato 4K S (fully tested - looking for feature testers!)

Example usage:

# Fix washed out colors from game consoles sudo elgato4k-linux --hdmi-range expand # Enable HDR tone mapping sudo elgato4k-linux --hdr-map on # Combine multiple settings sudo elgato4k-linux --hdr-map on --hdmi-range expand

The repo has full installation instructions, udev rules to avoid needing sudo, and technical details about the protocols. I'll be adding to Releases shortly for those that just want to run the binary.

GitHub: https://github.com/13bm/elgato4k-linux

Edit: For HDR10 support i used this repo https://github.com/awawa-dev/P010_for_V4L2

This is completely unofficial and community-made. If you have a 4K S and want to help add to development pull requests and issues are welcomed.

Hope this helps some fellow Linux users!

AC Odyssey ISDone.dll Error - Nobara

Reddit Linux_Gaming - 8 Oct 2025 - 12:23am

Hello friends.

I am trying to install AC Odyssey on Nobara 42 6.16.9. I tried both versions of gymgirl and dadi and keep getting the same error.

https://preview.redd.it/8xw23vigkrtf1.png?width=351&format=png&auto=webp&s=02a59269ab5f04cd0230aa34dcdb763b34b64940

I think i tried any settings i could find on Lutris, different wine versions (wine hq, ge 10, ge 8), i tried installed as new game of add locally. Tried any directory it provides (C/Z/X), inside/outside /home. I keep getting the same error. Ofc no AV to remove any "suspicious" files but besides that i did checksums also, no issues. I tried to run it directly from wine through terminal, same.

I have plenty of disk headroom (350gb), i have swap (8gb), i don't know what else to try or where to begin. I have never encountered that error with many successful installs so far (oblivion re, bg3, wreckfest, cyberpunk etc etc etc).

Any thoughts?
