Question / Help Worse stream with higher up/download and better rig

[Happy]

Hey all...

I ran into a strange problem I just can't figure out why it's happening. I started streaming some weeks ago and 2 of my friends already stream for some time. Problem is whenever I stream (especially high motion games) my stream has lags/stutter and theirs don't. Sometimes it's completely unwatchable (https://www.twitch.tv/sinisterhappy/v/95237439) cause there's just 1 frame every 10-20 seconds.
The reason I don't get it we have the same OBS settings and I have a better up/download and a better pc but still they don't have problems.

I added pictures of all my OBS settings and also a screenshot of a speedtest and an overview of my rig.

Additionally the last 10 logs :

if any additional informations are needed just let me know.

I hope anybody here is able to help me cause this drives me crazy...

Thanks in advance :)

No need to upload those screenshots, the logs include all data we need. But that are a few too many logs, I checked through the first few but everything looked pretty good. Barely any dropped/late frames.
It could be a combination of a taxing game (like Overwatch, think I saw it one of your logs) and the stream that sometimes your cpu runs into limits and thus the stream starts to lag. Would be good if you could upload the current log file after such a problem occured.

Here you go :) logs of the night 15th to 16th

And you're basically right but even games like Counterstrike lag a little bit...basically every game which includes faster movement.

And as far I am able to see (OBS and Task Manager) my CPU isnt even near the limit no matter what....the highest usage during a stream i saw was about 25% (even this seems massively low in my opinion).

Mhm strange, you are even using superfast and then ultrafast preset but it had severe problems:

• 02:35:19.469: Output 'adv_stream': Number of skipped frames due to encoding lag: 55178 (14.0%)
• 02:35:19.469: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 464 (0.1%)
• 02:35:19.469: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 13266 (3.4%)
• ...
• 03:29:33.448: Output 'adv_stream': Number of skipped frames due to encoding lag: 41703 (42.9%)

Encoding lagged, rendering had stalls/lags (although not too many) and your connection had a few problems at some point too, dropping frames. All in combination with running overwatch.

Your settings are normal, 720p 30fps, 2500bitrate. On your cpu I would have thought you can keep the preset on very fast with most games. 980Ti is also a good card. But you should probably see more than 25% cpu utilization from OBS on that settings with very fast preset at least.

My first idea would be to create a new empty scene collection and just adding one scene with a game capture to it. Then use your normal stream settings and test a bit if that works fine. Assuming its not the game and neither your system, sources loaded in your current scene collection could potentialy have an effect on the cpu and gpu usage coming from OBS.

okay think 5 minutes will be enough so give me 5 minutes ;) will try it out

 

[Happy]

okay here you go....new scene collection...

Overwatch seems to be too much for your system. Its definitely a heavy game and battle.net launcher tends to eat some cpu resources too but I am not totally sure why it hurts your system so much.
17:34:52.835: Output 'simple_stream': Number of skipped frames due to encoding lag: 15609 (71.6%)

You could see if lowering the Overwatch graphics settings a bit has a positive effect, but you mentioned other games also having problems, like CSGO?

 

[Happy]

CSGO doesnt have as much problems as Overwatch but still it has some small lags here and there. Its recognizable but not even nearly as punishing as Overwatch.

And I tried lowering my graphics settings down to medium already and the only thing happening was I have lower graphics...stream sadly had the same problems.

 

[Happy]

Okay I tested a bit and even with the lowest possible settings of Overwatch I have encoding lags of 10-50%. I don't get it. Why is this happening? Any ideas?

 

[Happy]

Okay...update. I managed to fix the encoding lags etc with switching the encoder and yes i know nobody recommends switching from x264 to NVENC but it works so I'm fine with it ;) quality is great (even random viewer watching my "problem test stream" said that ;D) and neither my CPU nor my GPU reaching above 80% and i don't drop frames or something.

Only problem I ran into now is that the desktop audio is skipping about half a second every 3 or 4 seconds which is a little bit annoying to be honest. So anybody has an idea or know what could cause this problem or even knows how to fix it?


Here the log of the last test stream:

The last part (1:59) is the fixed version
