IMMEDIATE frame drops when using the Nvidia Background Blur sdk Filter

In the past I tried out using the Nvidia Broadcast App to blur my camera background but was having issues with dropping frames and time to render frames. I now am running a MUCH better PC and with the Nvidia SDK integration into OBS 31, I figured I would give it a try again, but ran into issues as SOON as I hit the "start streaming" button with dropped frames. What could be causing these issues??

PC Specs: i7-14700K, 4070TI Super, 32GB RAM, Elgato Facecam MK.2

Sorry to see nobody has replied. I have done a lot of testing here on mine, i have elgato facecam as well and I made sure that im only either using nvidia broadcast or elgato camera hub, it seemed and still seems to make it ''less'' unstable. and then there is the option of only running nvidia webcam filters in obs while using elgato facecam instead of virtual and killing camera hub and or nvidia broadcast and just not using them but then again the sdk obs filter plugin seems very pixelated around the user on camera. Although in my time of experimenting and researching this i have found out that elgato facecam and the camerahub software just simply arent very well optimised and found some complaints about it in reddit forums to be exact. Hope my response wasnt a case of ''too little too late'' good luck!

I've been facing issues recently despite re-installing all drivers and NVIDIA programs. Downgrading NVIDIA Broadcast to version 1.4 (from 2.0) didn’t help, even after using REVO and DDU and making system clean from anything Nvidia. When using the NVIDIA SDK for background removal and doing scene transitions with Exeldro's Move Transition, render times spike, frame rates drop, and then stabilize after some time.

Workarounds I found so stream works:
  1. Disable NVIDIA Broadcast sound effects (noise/echo removal), and then rest works fine
  2. Disable Exeldro's Move Transition between scenes but keep NVIDIA SDK for background removal
  3. Uninstall NVIDIA SDK, keeping sound effects and Move Transition but no background removal
The standalone NVIDIA Broadcast (non-SDK version) works better on both my PC and streaming laptop. It delivers superior sound quality and noise elimination compared to the SDK. I prioritized SDK in the effects chain, but standalone performs better.

Everything worked fine two weeks ago, even with an older OBS version on my laptop (RTX 3070). Now, both old and new OBS versions cause issues. My gaming PC (RTX 4080 Super) sometimes shows render lag notifications, even with the latest NVIDIA and OBS updates. On Sundays, I stream lighter games like Jackbox directly from the gaming PC without major GPU strain but encoder notifications and smaller drops are noticable.
