Hi, as far as i know OBS does some work composing the image before it goes to the selected encoder and then it's either streamed or recorded, now, it's there any way to select what GPU OBS uses for the video composing? Cause if that was possible a weak GPU could be used for that and would leave the main GPU totally free for the games. If it isn't possible i would like to know why, thanks! :D

Also, OBS' usage of the GPU is minimal at best, under 1%. Moving the compositing/scaling/color conversion to a dedicated GPU would have no visible impact on performance. In addition, it would slow down captures and have significant impact on the system bus load. At present OBS just copies video frame data from one point in VRAM to another for capture, without ever leaving the video card until the finished frame is complete. If moved to a secondary GPU, it would have to push the uncompressed full-frame data into the VRAM of the second GPU.
In short, few gains for significant potential performance impact.

Ooh i see, thanks for replying and giving info!
