A comparison between a x11grab capture and a Shadow Cast capture
[ Ссылка ]

The first part of the video is captured using x11grab via the FFMpeg cmdline utility. It's captured at 30fps, 1440p, with the hevc_nvenc encoder. The artifacts are horrible, and the in-game performance suffers a lot too, as can be seen by the MangoHud display.

The second part is captured using Shadow Cast, 60fps, 1440p, with the hevc_nvenc encoder.
