Question / Help OBS Lagging on every streaming RES possible.

[tekkaadan]

I have been running into a pretty significant issue with OBS lately. Its been lagging like crazy. My bitrate can be 6000 since I get around 9-11 mbps for uploads and 100 mbps for downloads. I have tried using everything, even formatted my computer just for this and I still can't seem to get rid of this STUPID lag. I have a seperate graphics card in my PC just to try if I can use NVEHC or whatever just for that and its still crappy. Heck, I can't even stream at 600p 60FPS on it either.

I have tried everything. I know for a fact that my PC can handle 1080p 60FPs no problem, but I can't even stream the minimum. I have attached all the logs and my Twitch Bandwith Test. I have also linked my PC build for those interested and it also includes the GTX 1050 as an extra card in there.

I really hope someone can help me out here!

I would suggest removing the 1050. If the app you're trying to capture is running on a different card than the one OBS is rendering on, you'll have a huge bottleneck.

In addition, depending on how many PCI lanes the slots on your motherboard have, you may be reducing the performance of both the 1050 and the 2080 just by having both installed at once.

This may be a reason why you're getting rendering lag when it doesn't seem like you should be.

19:35:46.270: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 1646 (2.7%)
18:59:26.715: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 367 (9.5%)
18:57:59.551: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 1077 (8.0%)
19:13:40.170: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 11029 (22.3%)

That is just for testing purposes. Even if I remove the card. I still get the lag.

Using just the RTX 2080

Can you provide a log from the above session, please.

 

[tekkaadan]

and this is me streaming at 600p 60FPS... LMAO

And this is the log for then 600P session.

Latest logs here:

Neither log contains an output session. The first one did. You need to stream or record and observe your problem, then stop the stream before uploading the log. Without that, there is no performance data in the log, just startup.

Is there a reason why you increased the canvas resolution between the first log and the last two from 1920x1080 to 2560x1440?

Just to test it but I solved the problem via the OBS Discord Channel. MY GPU was apparently overloaded and I needed to capture game rather than screen. It works now!
