Question / Help OBS Studio 64 Bit, infrequent/periodic dropped frames

[ravagetalon]

So I'm having a bit of a strange issue that I can't seem to nail down. I'm experiencing fairly infrequent, but somewhat consistent dropped frames to Twitch. I'll drop anywhere between 0.1% to 0.5% of frames over a 3-4 hour stream. The odd thing is, using the same x264 settings, bitrates, resolution, and framerate in XSplit results in no frame drops over the same period. (Medium preset, 1280x720, 60fps, 2900 kb/s video, 160 audio)

I've uploaded the latest log of a recent stream where I dropped about 0.2% of frames and I also have a screenshot of the TL Twitch Bandwidth tester.

Thanks for your help.

16:57:05.599: [x264 encoder: 'streaming_h264'] preset: medium

Use a CPU usage preset of faster or fast. Anything below fast will not increase quality by a noticeable amount. Medium is just putting a lot of CPU to waste.

I will drop the preset to fast and see what happens.

It appears I'm still dropping an small amount of frames even at fast, faster, and veryfast presets. I've attached the latest logs from my recent stream. THe only oddity I notice is at certain points I get "Adding x ms of audio delay" or something along those lines, which I'm not sure what that means.

My twitch bandwidth tester is producing consistent results with my original test above, so I don't believe its network related, but it could be still.

Anyway, any thoughts would be appreciated. Logs attached are from two seperate streams. Between the two I lowered my bitrate a little.

Someone found this post for me. And it's still a rather new post too. First thing I thought of reading this was it's exactly what I've had experienced that started about 9 days ago. Never had such problem for years using the same settings of 720p 60 fps 3500 bitrate. Everything else defaults. OBS would even drop frames with an empty stream with no sources. And there's connection spikes according to twitch inspector. While Xsplit using the same settings encountered no dropped frames or connection spikes at all.

I think it's the way OBS uses CBR to communicate because I've tried disable that in classic mode and there's no dropped frames unless I intentionally spin my camera for extreme fast movement forcing bitrate usage to go up.
