Question / Help OBS Studio Render Lag [Solved]

[Yelby]

I lost hope on this until recently when I found a stats button. I recorded some of what was going on, and it can be seen the jumps in the video.

Turn off multi adapter compatibility if that's set in your game capture source.

Multi-Adapter Compatibility is not on currently.

You have multiple game captures, be sure to check them all. Also you have a lot of display capture sources, which generally perform bad. You may want to split up your scenes into separate collections to minimize the number of active sources.

Oh, I assumed that the scenes would de-activate each time it switches, so while in lets say my Streaming scene anything from my others would be deactivated.

No, all sources remain loaded at all times regardless of which scene they are on. This is what allows you to do custom transitions / studio mode or add a scene to a scene for example.

Alright, give me a couple minutes here I'll do another test run of the footage, if it still comes out choppy I'll upload the log.

Well this gave me new found confidence in my computer's capability. If it was able to render multiple scenes of 1080 at one time makes me feel good. Thank you R1ch for helping me with this! It just all of a sudden happened and I had no idea how to fix it.

At times I also had lost frames in "rendering lag". I finally experimented with various settings and now know what "rendering lag" really is about. It is frames that you ask OBS studio to capture (in Settings Video, where you set your canvas size, you also set your FPS) and the game is rendering less than the requested frames.
I just made a video that explains it a bit better with OBS studio setup shown: https://youtu.be/cG4frVTPArE
And it is normal to always have some frames in there, due to switching resolution at game start, or initializing the video settings for the game, or switching levels/maps/ etc... So it is rarely zero. Only worry when the percentage is becoming not close enough to zero (like 0.3% would not be good for a stream that took x hours). But if you have like 100 frames lost in rendering for a 4 hour stream, then you are fine.

R1CH,
I've been trying to suss why my rendered frames were so high for a week now with a 6700k and 2080.
Turns out my AFK Scene while plays a large video file was always playing and all I needed to do was tick the "Close when not in use".
Rendering time went down to less that 1ms from like 6 and I drop 0 frames now.
THANK YOU!
