NVIDIA Noise Removal isn't Doing Anything?

Hello, I am trying to use the NVIDIA Noise/Room Echo removal in the Noise Suppression filter. When I enable RNNoise it clearly changes my mic audio, but none of the NVIDIA options do anything while they are selected. I have the SDK installed from NVIDIA,and I have the NVIDIA Broadcast app installed (but not currently running). The effects work when I'm routing my microphone directly through the Broadcast software but the built in support in OBS doesn't affect the audio. I'd rather not have to keep the broadcast app open all the time, especially when not using a webcam for video effects. Can someone help me troubleshoot why this is the case and get it working? I'm running OBS 30.1.2 on Windows 11 with an RTX 3090 GPU. ..

I'm not so much a noob as completely ignorant about OBS and tech stuff more generally. Yet, I opened an account here cause I thought just maybe I had info that could help AndrewCarsten and (if your not the same person) KHZC

I am running OBS 30.2.0 (updated today, though I noticed what I'm about I'm about to share with you to a week ago) on Windows 11 with RTX 3070.

So I heard a lot of hype about the NVIDIA Noise Removal filter, but it didn't seem to "do anything" until one day it did--and ooh boy howdy... I was literally hitting my car keys against the shock mount (outer and inner rings) and no sound at all!! A-MAZE-ERRIFIC ! ! ! (I had to drop it to 0.80 because it was cutting initial plosives after I'd been quiet for a while... but I might just kick it back up to 1.00 and train myself to always say "uhm" whenever I start talking)

...but then next time I boot up, back to nothing. Turn the filter off and back on again--no difference

I would guess that this fancy filter "showed up" about 1 out of every 20 to 30 times I opened OBS (I boot up my PC and use OBS at least once every day)

Then, prompted by OBS to update some NVIDIA something I didn't understand what, I notice that I can start OBS from the GeForce App. Before I had always used a shortcut to OBS in the taskbar. On I whim I tried it ('Oh, I can open stuff from here?' If that whim had had me open TLUS you wouldn't be reading this.)

I've only be at this about a week, but golly-gosh-dag-dernit if EVERY time I start OBS from GeForce that NVIDIA Noise Removal Filter princess doesn't do her magic. I'll even test in with a shortcut open (nothing), then close it out and reopen immediately from GeForce and there she goes!

Can anyone explain this to me?

Looks like no one has read this post... which is really good, because...

I'm running OBS 30.2.3 now and the situation is the EXACT OPPOSITE of what I described above. (Now the "noise suppression" filter works like a charm when I open OBS directly, and doesn't work when I open it through the GeForce App--this was the case both before and after I updated the GeForce Driver to 561.09 yesterday)

Why would the functionality of a mic filter depend on where I opened the OBS from? Why would it switch from "must open through GeForce" to "must NOT open through GeForce"?

I dunno--finicky behavior form the NVIDIA filter is annoying, but I'm quite happy it still seems to work in at least one of the pathways to opening the program. Of course, I can't know WHICH pathway will work on a given day, but there are plenty of things in this world I can never know
