On Pop OS, you can select the 'NVIDIA Graphics' option in the power menu, or on Arch Linux you can use Optimus Manager.\ If you are using a variable refresh rate monitor, then choose to record "screen-direct". This will allow variable refresh rate to work when recording fullscreen applications. Note that some applications such as mpv will not work in fullscreen mode. A fix is being developed for this. +### TEMPORARY ISSUE ### +screen-direct capture has been temporary disabled as it causes issues with stuttering.
