Question / Help Dropping Frames all of a sudden

After a while of decent streaming, where dropped frames was less than 1%, things have gotten ridiculous. My attempt to stream friday was the first indication, after changing ZERO settings, that things hit the crapper. I went as far as to move my whole setup in order to run the ethernet connection direct as opposed to wifi. Nothing changed as far as the stream. I was going to twitch...laggy. went to yt. laggy. restream. same thing. I've tried reducing my BR from 5800 to 5000 and from 60 to 30fps. Even though I have the BR set, i notice that in the lower right corner of OBS the br is all over the place. Sometimes going as low as approx 2300 to over 7000. I'm pretty sure i have it set to CBR so i don't understand why it jumps so much.
Anyway i've attached the latest log file that was going to YT. As you see at the bottom, almost 10% loss which is crazy when i have 150up and 15down through the isp :S

Unlucky dude.

Pls try changing your profile to High instead of Main.

Can you completely uninstall and reinstall OBS? Be sure to remove any leftover files? It sounds like you're stuck on a different rate control method and for some reason it's not changing. A good solid reset might be just what you need. If you have complicated Scene Collections that you want to save, export them, then reimport them after you've confirmed you're good to go.

You machine is ok, your settings are ok, but your internet connection is not:
00:05:08.844: Output 'adv_stream': Total frames output: 36491 (40448 attempted) 00:05:08.844: Output 'adv_stream': Total drawn frames: 40484 (40487 attempted) 00:05:08.844: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 3 (0.0%) 00:05:08.844: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 3957 (9.8%)

Hi Koala,

Prior to submitting this last night i did follow that guide. I just find it very strange that major lag/dropped frames issues seemed to come up out of the blue on Friday.

Hi Agamemnus,

Thanks for the tips. I'll try changing the profile to High before doing a full uninstall/reinstall of OBS. As mentioned to Koala, I just don't understand how it goes from working relatively well to essentially garbage :(

Hopefully something will work :)

Thanks again everyone.

@koala is right when he points to your network as the reason for the dropped frames. The thing that I'm suss on is how you said it fluctuates from 2Mbps to 7Mbps. It makes me think that somewhere in your config files is some little detail that is stopping it from doing CBR rate control, even though that's what's showing in your log. It's a mighty large fluctuation! And if your config files are keeping it going, then a fresh reinstall might do the trick of clearing them, so your OBS can start with a blank slate.

If this is indeed the cause, then whenever you have a sudden fluctuation, that will be when you suddenly drop a whole bunch of frames. The only reason I say to do profile = high is because the profiles specify a conformance set that the encoder will try to maintain. QP vs Cr and Cb controls are in high, so is transform adaptivity and a Q scaling matrix or 2. I don't imagine that this is supposed to directly cause the fluctuations that you're seeing, but it's possible that it's (mistakenly) led to it. Just eliminate the possibility, and find the next clue until you're done.

There are numerous possible causes for bandwidth issues to your streaming service. Many of them completely out of your reach. Possible cause within your own network, for example: some other user in your local network/household is uploading stuff while you are streaming. It does not need to be a person, it does not need to be manually started: some cloud synchronizing of new data that runs in background is often overlooked.
It's also possible that your internet provider changes the routing/peering points with other internet backbone providers, or or the internet provider of the streaming services does this, and this may make your connection to your current streaming server bad. Because of this, the first recommendation from above guide is to check and change the server.

After a reinstall, and making sure to delete the folder %appdata%\OBS before reinstall, it's still not perfect :( The latest loss was only .2% so i might have to just be happy with that and hope it miraculously gets better like it miraculously got worse.

Thanks for all your help. I've attached the latest log files for you to see what's been going on :)
Cheers,

SG80
