Preview/Program Issue

[ProSouth]

I can post a log file tomorrow when I’m back at my studio.

However here is my issue.

My stream and the recorded file plays just fine but my preview/program windows get laggy or choppy. Sometimes even freezing entirely then quickly catching up.

The oddity to me at least is my cpu and ram usage are absurdly low. I never get above 5% cpu and I have 96 GBs of DDR 4 RAM running in dual channel.

It’s also very intermittent. Sometimes during our two/two and a half hour streams, we get a lot of this, sometimes we get very little. Any advice would be helpful.

I’ve seen something about RivaTuner being used to force OBS to cap its frames which according to some posts alleviates this. I have no idea how to use RivaTuner and most of this I’ve learned by trial and error.

Your configuration is not really optimized for OBS as OBS works best with a single GPU. If there's a way you can make due without the 5th monitor/1660 in the mix, do it.

Take care of the stuff the analyzer pointed out. Check all plugins make sure they are up to date. Vinci looks like it may be throwing errors. I would disable Hardware Acceleration on the Media Sources that it is currently enabled on, I counted (5) of them. Your system has a nice bounty of RAM but VRAM is somewhat limited so save it for something else. Check for conflicts, I believe Riva is just that. Run another test after all is completed, see if that Preview smooths out.

It looks like this file may be the cause of the SEI warnings. Playback is @ 200%? Try 100% & see if they go away.

Your LAN looks good but bandwidth seems to be an issue. May need to drop the bit-rate or try enabling Dynamic Bit-rate.

21:17:47.674: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 4003 (0.9%)

I’m gonna post my next log file. We didn’t drop any frames according to obs but our stream was laggy on both the preview side and YouTube’s side this time.
