New OBS Lag.

We've had issues with lag lately. I'll post 2 logs one for Thursday and one for Friday. We haven't changed settings before these events. So my main concern is why in other games like KH: BBS which we played for 6-8 streams without issue do we now have issues.
We have lowpoly models models rendered in Warudo if that helps too. Lately (I never checked before) OBS takes up ~20% GPU, even just sitting there not streaming... what's that about?!
CPU doesn't ever gets past ~50%, should I switch to CPU encode? I'm at a loss as to what the issue is all of a sudden. We even tried shutting down EVERYTHING and only having OBS and a game and it's still not ideal. Can a 3070 not run OBS and 1080p gaming? That doesn't seem right...

PC Specs:
CPU: Ryzen 5800x
RAM: 32GB
GPU: 3070gtx
Internet: Gigabit Fiber

Thursday: Playing Split Fiction on a 4K screen. Restarted OBS multiple times so the % errors in log might be off compared to Friday log. Its obvious playing at 4K is not a smart move. We're not doing this anymore but I figured it might help narrow down issues.

Friday: Same game this time on a 1440p screen but resolution scaling on at 50% (1810x1018?). Anything more and it lags fully. Full 4hr stream. Still had some minor issues here and there. GPU doesn't ever hit 100% on this run I don't think.

Ugly, your PC isn't doing anything fast. You should check each & every plugin. Move, Stroke Glow are stale & need to be updated. There's possibly others too as I did not bother to check them all. Also, your Distro/NDI install has a conflict, v5 runtime is in the mix.

8:00:04.525: [DistroAV] load_ndilib: NDIlib_v5_load found

If things don't improve after those updates, I would test with a New Scene Collection, add just (1) Scene/Source. The current collection is a house of cards.

This is from your 4k session, the other logs are incomplete. Rendering Lag is GPU overload but your encoding settings were good, so eliminate the Rendering Lag & most if not all of the encoding lag will go away.

19:33:06.346: Output 'adv_stream': Total frames output: 332473
19:33:06.346: Output 'adv_stream': Total drawn frames: 306782 (335984 attempted)
19:33:06.346: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 29202 (8.7%)
19:33:06.347: Video stopped, number of skipped frames due to encoding lag: 37928/335929 (11.3%)

When you run the next test, drop the Gigabyte to 120HZ & the secondary monitor to 60HZ. This will help to drop load & some VRAM.
