We provide https://github.com/nowrep/obs-vkcapture as the obs-studio-gamecapture package.

1. Please note that for Nvidia cards you need driver version 515 or newer due to the Nvidia proprietary driver missing support for VK_EXT_external_memory_dma_buf Vulkan extension in older versions. Without this extension nvidia cards do not work with Game Capture.
   
2. First you need to launch the game using ‘obs-gamecapture’, like so:
   
   obs-gamecapture somegame
   
   For example, to use this with a steam game in the game’s steam command options:
   
obs-gamecapture %command%
   
3. Launch OBS. If you are using X11/Xorg instead of Wayland, you will need to open a terminal and launch OBS with OBS_USE_EGL=1:
   
   OBS_USE_EGL=1 obs
   
4. Then in OBS click the + icon under the ‘Sources’ list and choose ‘Game Capture’, then press ‘OK’. You do not need to pick any kind of window, it will auto-capture when the game is launched.
