NVIDIA noise suppression is causing fame drops in OBS 27 while not streaming

I've had problems with OBS 27 ever since the update, which led me to continue using the OBS 26. Recently I upgrade my CPU to Ryzen 7 5800X. Decided to test out OBS 27 to see if the problem still persisted. Unfortunately it did. I've always thought it was some graphical issue the whole time so I started messing around with the sources and settings. Still nothing. Keep in mind I had no problem with OBS 26. No frame drops, no stream drops. I started thinking the only thing I changes was the noise suppression on the Audio input. I turned it off and no frame drops at all. Now I'm curious if it was the cause of encoding error during stream. I'll be testing streaming later tonight, and hopefully everything stays afloat. But I was excited for this feature in 27 but if this is the cause of my stream being unstable, I'll be crying in the corner for few days.

Make sure the Preset for NVENC is set to Quality (not Max Quality) and the boxes for Look-ahead and Psycho Visual Tuning are not checked.

Just tried that setting. Right when I turned on the NVIDIA noise suppression my frame rate started dropping. I also tried having Audio input source directly in with the scenes instead having it as a separate scene and this also did not work. Gonna try streaming with it now and hopefully I don't get encoder error this time.

Quick update. Just finished streaming for two hours. No problem at all. So unfortunately I'm having issue with the built-in Nvidia noise suppression. I guess I have to use the NVIDIA Broadcast for the noise removal for now.

Not sure what AAC means, but usually when your streaming at much higher load than your gpu can handle, you get this error. When built-in NVIDIA noise suppression turned on, frame rate drops and just everything goes wrong

Nvidia Broadcast is overly bloated for what it does.
Better off looking at Reaper VST plugins to control your audio elements, though admittedly they're not a 1 click solution.
