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.\ GPU Screen Recorder only supports h264 and hevc codecs at the moment which means that webm files are not supported. ### TEMPORARY ISSUES 1) screen-direct capture has been temporary disabled as it causes issues with stuttering. This might be a nvfbc bug. 2) Recording the monitor on steam deck might fail sometimes. This happens even when using ffmpeg directly. This might be a steam deck driver bug. Recording a single window doesn't have this issue. -3) Videos created on AMD/Intel are in variable framerate format.

Use MPV to play such videos, otherwise you might experience stuttering in the video if you are using a buggy video player. Try saving the video into a .mkv file instead when using AMD/Intel, as some software may have better support for .mkv files (such as kdenlive). ### AMD/Intel root permission When recording a window under AMD/Intel no special user permission is required, however when recording a monitor the program needs root permission (to access KMS). To make this safer, the part that needs root access has been moved to its own executable (to make it as small as possible) and a GUI sudo prompt is shown to run this executable as root.
