I think the low efficiency of OBS Studio streaming is because OBS Studio defaults to compress the encoded video
Because every time I record a video, the Game DVR (Windows 10 XBOX) recording video is larger than the video recorded by OBS Studio
And it seems that OBS Studio does not support recording DirectX 12 games, and when I record PAYDAY 2, recording FPS will affect my game FPS. These problems have never been met in Game DVR
The following link is my OBS Studio log file, just yesterday, I changed the computer configuration, and after I re-tested, the game DVR (Windows 10 XBOX) recording more efficient, OBS Studio recording is very bad
