OBS Lagging whenever i start streaming

Hello there Brothers and Sisters,

for about a year straight now i have a huge problem with my OBS Studio streaming software. That is why i haven't touched if in months.

Whenever i click the "start stream" button, the feed in OBS itself starts lagging a bit or at least, doesn't look as clean and fluid, same goes for the actual stream, no matter what platform (Twitch + YouTube). If i only use 2500 bitrate, it is already clearly visible and only gets worse whenever i put up either resolution or bitrate.

All logs of yesterdays attempts are attached to this post!

It all started for me last year if i remember correctly, when i first tried out the new NVIDIA NVENC H.264 (new). Eversince then it appears no matter what i use, even if i use my CPU.
My internet connection can't be the problem either. Depending on daytime i got between 100k-110k Download + 40k-65k Upload.

Here comes the twist:
I test-streamed a couple of times on YouTube using Nvidia Shadowplay's Broadcast LIVE function. 1440p | 60 fps | 20k bitrate. NO ISSUE! No laggs, no nothing. Working just fine.

I am desperate at this point. I want to stream again using OBS to implement scenes and all them goodies. It's my hobby.

You guys are my last bastion, my last hope.

Best Regards
Kevin

In most of these logs you appear to be simply overloading your GPU. Make sure you are properly capping framerate in any games that you play.

OBS requires GPU resources to composite your scenes, which in your case are also extremely complex and have tons of filters and other GPU-intensive sources. You might want to consider trimming things down, or breaking things out in to different scene collections for scenes/sources you don't need for every stream.

Thx for your answer buddy, appreciate it very much!

So it is all issues thx to my scenes then u think? Cause it is even lagging on 1080p 60fps 2500 bitrate. Didn't do that till like exactly one year ago. Same scenes though.
And compared to MAX settings Escape from Tarkov in 1440p 60fps 20k bitrate with Shadowplay LIVE, i wonder if a bunch of picture- & videofiles + filters can do that much harm?

Will try that buddy, thanks my dude <3
 
Bitrate has no bearing on performance. However, 2500kbps is nowhere near enough for 1080p 60fps to look decent, you need closer to 9000kbps, which is likely contributing to the overall quality issues you are seeing. I'd recommend lowering to 720p60fps at 6k bitrate and see if that works better.

True that. The 2500kbps was just to test if a low bitrate would get rid of laggs and stuff. My initial goal was to stream in 1440p 60fps with around 25000kbps on YouTube to match my experience with my ShadowPlay LIVE streams.
But if u say my scenes are taking away so much of my ressources, this goal seems to be unreachable with OBS and scenes implemented.
 
Shadow play doesn't composite, so it's not exactly a fair comparison to your setup with dozens of different sources and filters. You just need to understand that it's not free to add that stuff, and you might need to temper expectations. The GPU is what is being overloaded, so making sure you're capping Fps to 60 in the game would be my first starting point.
 
Rendering lag is GPU overload, not cpu. Encoding lag is Nvenc itself, which should be 0 on your case.
 
Well, my issue still exists unfortunately.
Stripped down my scenes, tried out both NVENC and x.264 with the CPU being at like 10-15% during recording, STILL my issue is right there. No matter if i record, no matter if i stream. As soon as i do it with OBS i have these issues. Changed resolutions, no change.
I have micro laggs & stuttering and the video in general doenst feel as clean/fluid as it should be and did a year ago, before i started having these problems.

I got the logs of my test records attached.

Again: Before this issue appeared, i could stream 1080p 60fps 10k bitrate. Wasn't a problem. Still have the same internet connection, still have the same hardware.
