Hello! Again have a problem with drop with framerate while recording (or with streaming). I tested the capture card without OBS. It was done with direct ffmpeg running. With direct running I have not found any problems with recording video. Someone held this bug with OBS? Any solution?
Stop answer about network speed or video bitrate, problem not in these case.
