obs-vkcapture VS gamescope

I can't speak for Chrome nor VMWare, but Firefox and OBS have received "Wayland native" screen capturing functionality, through XDG portals and Pipewire, as far as I'm aware.

As a side-note, I've recently discovered a really cool project[0] that enables incredibly fast screen capture for OpenGL and Vulkan applications, mostly tailored to games. Tried it with a bunch of stuff and it works much better than both X's and Pipewire's screen grabbing. I can actually capture videos at my monitor's native refresh rate (144Hz).

Hello, so I use this OBS plugin obs-vkcapture. I use it as opposed to the built-in Window Capture, because with that option I would keep having to alt-tab back into OBS to select the game I want to record. This plugin is basically the "Game Capture" feature on OBS Windows brought to Linux. It makes it to where I can put a Steam launch option obs-gamecapture %command% and launching the game will make its executable show up in the Game Capture source, so I can just press record on move on, no more opening OBS to select the game's window and risk nuking it when alt-tabbing. It is much more performance efficient and it's a package/patch that is included in GloriousEggroll's Nobara distro's build of OBS as well. I however use it on Arch from the AUR, it's the only AUR package I use in fact.

I was using https://github.com/nowrep/obs-vkcapture but I also had Proton-GE 7-49

Back in december when I tried I had some success using this https://github.com/nowrep/obs-vkcapture

Additionally, I'd like to use Game Capture in OBS if possible via obs-vkcapture. If using this with gamescope, where do I actually put the variable or obs-gamecapture command? Does it wrap the entire gamescope command, or does it get wrapped by gamescope?

I think you mean obs-vkcapture-git. It lets you capture a window through Vulkan. Here is also its github repo for more informations.

I have spent a few hours trying all kinds of dependencies on Fedora 36 Workstation trying to get obs-vkcapture to compile. I have found the exact ones and hopefully it helps someone in the future: cmake gcc gcc-c++ obs-studio-devel mesa-libGL-devel vulkan-loader-devel Here is a convenient command to install all at once: sudo dnf install cmake gcc gcc-c++ obs-studio-devel mesa-libGL-devel vulkan-loader-devel

Maybe gamesope can help? Games are nested into it to allow for better control.

Well I suppose you should start taking Wayland seriously then, because gamescope, the compositor on the Steam Deck, uses Wayland. https://github.com/Plagman/gamescope/blob/master/src/wlserver.cpp

Mini-update: I spoke with Josh (and Strudel, who referenced me to the PR), and this has been already merged into gamescope.

Valve staff is also aware they cannot force developers to retrofit 16:10 support into existing games (some do, many don't), so they even go the extra mile to provide extra functionality in gamescope to improve the 16:10 gaming experience for games that only support 16:9 natively.

The ganescope github has all the commands and how to use them: https://github.com/Plagman/gamescope

I'm trying out gamescope on my laptop, and I came across ChimeraOS's fork of it. I'm not sure why I would choose one over the other. ChimeraOS mentions something about "session switch", but I'm not sure what that's about.

You can use gamescope on the desktop, I use it for a ton of games like No Man's Sky, Bethesda games, and any others that have alt tab instability.

For those that don't know (like me, three minutes ago) gamescope [1] is a Wayland compositor custom-written for games (and, I believe, what the Steam Deck uses). it's open source, and under the "BSD 2-clause" license.

I assume that this is because I'm still using ye olde steamos-compositor (https://github.com/ValveSoftware/steamos-compositor/.) I'm interested in switching to gamescope (https://github.com/Plagman/gamescope) but I'm getting the feeling it won't work on my 20.04 vintage Ubuntu; the required version of meson isn't available and I can't find a PPA that contains gamescope. My instinct act this point is to just live with the pain, as fully dealing with this will likely involve just switching all the way to Arch to more closely match the newest SteamOS and I just don't want to do that right now. Anyone know if there is a middleground that will support a modern steam big picture mode without having to totally redo everything?
