Frame Drop when streaming TEB with a RTX 4060

More trying to pick a few brains with this one but have a Canvas built at 1440p with no downscaling. Within it I have my Camera feed which is sent via Teleport with a NVIDIA Background Removal Plugin ontop of my Capture Card using a Source Clone, with a Composite Blur filter, to fill the Background. Everything is set to 1440p60 limited color range with 701 space, no issues when idle but will start stream and suddenly drop to sub 50fps on output. I only have TEB enabled for 3 sessions and no other output is being generated. I can post the log after work but just curious I'd anyone has came across similar situations

first log is before i installed source profiler, second log is afterwards which lead me to see that teleport with a background removal and source clone with composite blur may be the culprits

More often than not you can use the OBS Log Analyzer to tell you what's wrong: https://obsproject.com/tools/analyzer For your first log, you're losing 37% of frames to render lag and and 37% of frames due to encoder overload The second log is worse with 64% due to render lag and 61% due to encoder lag Render lag is when you're taxing your GPU enough that it can't render the sources and effects before encoding, and encoding lag is overloading the encoder portion of your GPU You'll want to decrease your settings, possibly your sources and effects as well. One example is that you're using preset p5/p6 for encoding, which is extra taxing on the GPU, on top of running both lookahead AND psycho-visual tuning which are also intensive. You'll want to lower those presets down to p1/p2

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

Can't use p1/2 for enhanced broadcast. They set those themselves with no user control(and IMHO some of them are a bit too aggressive)

OOF Do they let you specify any settings?

Nope not really Just number of encodes and target bitrate if you are limited The rest is auto-magic

RIP So basically, GPU isn't powerful enough to do TEB with the setup above The main thing to me is to get rid of that source clone and blur setup, that's probably very taxing on the GPU

Yup which is why I dropped the 5 encode ladders down to 3 to help with that as idle my frame time was barely over 8ms average and suddenly jump up to 20ms when I hit live. And that pc is strictly just streaming to twitch. Not gaming on it or recording on it Hell my gaming PC today had no issue streaming 1440p HEVC to YT and 1080p Vertical H.264 to Tiktok while recording game and camera separately at their respective max resolutions. All while the stream pc just struggled to handle TEB Ideally we would like control to do like say 2 ladders with 1 being 1440p HEVC and the other being 160p AVC but TEB requires a mid and max for AVC before they allow HEVC I'm about to do a clean build again this weekend and slowly just add in the sources and see where the issue is coming from Just saw the last message, I disabled them today and still no improvement. Source profiler showed a 5% GPU usage but nothing in my main scenes added up to it, even if tripled so something is missing

Do you remember what presets you were using for all those encodes before you started doing TEB?

Can't adjust the presets for TEB unless you mean on the Gaming PC
