Question / Help Choppy OBS Playback?

21:47:07.876: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 102 (5.1%)
21:54:55.186: Output 'simple_file_output': Number of lagged frames due to rendering lag/stalls: 60 (2.6%)
21:52:12.062: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 59 (3.2%)


GPU overload.


21:50:15.255: Video stopped, number of skipped frames due to encoding lag: 1945/2054 (94.7%)

21:54:55.187: Video stopped, number of skipped frames due to encoding lag: 70/2284 (3.1%)


You've got multiple attempts here, some using NVENC, some using x264. You tried x264 using the slower preset, and that caused 94% frame drops. That recording would be utterly unwatchable.

The 3% drop with NVENC would have noticeable stutter. To try and improve that, you can turn off psycho visual tuning.

21:48:37.401: [x264 encoder: 'recording_h264'] preset: slower
21:48:37.401: [x264 encoder: 'recording_h264'] profile: baseline
21:48:37.401: [x264 encoder: 'recording_h264'] settings:
21:48:37.401: rate_control: CBR


CBR isn't the best choice for recording. It results in larger files with no increase in quality.

Use CRF and a quality rating between 14 (very high) and 23 (pretty good).

Or with NVENC use CQP.
