PSA: Nvidia broadcast plugins for LGHUB and iCue using 1GB+ of RAM + VRAM (How to fix/remove)

[Mussels]

TL;DR:

Icue + LGHUB w/ Nvbroadcast enabled

After, with Icue, LGHUB and NV Broadcast removed manually

I found this out the fun way, by updating LGHUB and iCue and discovering they both use Nvidias Broadcast plugins.

Sounded good, gave it a try - due to having a decent mic no one at the other end noticed a difference anyway, so I tried to uninstall it.
And I couldn't.


I checked task manager and... Oh. Oh no.
The moment a microphone was in use, RAM usage skyrocketed to the point that a lot of users would have serious performance issues.

All up, i was losing 3.5GB of RAM - and users who went testing further on Reddit found it used almost as much VRAM as well.
This is a f*cking disaster for Nvidia cards with 3GB or 4GB of VRAM.




Uninstalling LGHUB and iCue DID NOT FULLY RESOLVE THIS.
The windows service still used 1.3GB of RAM with everything removed, as soon as a mic was in use.


This parts entirely Logitechs fault: they hid the uninstall button for NV broadcast, the hidden button doesn't work, and uninstalling LGHUB does NOT remove it.
iCue definitely has increased resource usage, but uninstalling their addon actually worked - Logitech's version was using RAM + VRAM when I used my corsair headset mic, which is not corsairs fault.

Logitech hid the NV broadcast uninstaller behind the Nvidia logo here, but it doesnt uninstall the plugin - nor does uninstalling LGHUB entirely

The Reddit Rabbit Hole finally had a solution:
Delete the contents of this folder:
C:\Windows\System32\logi_denoiser

Side note:

Fired up a game i was testing over/underclock settings on last night, and found i'm now 30FPS higher with that removed
This is just.... uggggghhhhh

Well done,
We pay products too expensive to get a bloatware not optimised, it's often a software isssue
I never use Nv crap or LgCrapHub ; I use Icue who need too much ram but it's fine (still poor optimisation)

I had Icue installed before I uninstalled LGhub, ?I have the other programs installed but did not have them running at the time of getting rid of LGHub. The services were uninstalled as well in the one process.

ICUE is shit use openrgb.

Did you install NVBroadcast within LGhub?

It's an optional setting that only shows for supported microphones

ICUE is shit use openrgb.

Yeah cool, I assume it sets my fan speeds on the commander pro?
And changes the headset from stereo to 7.1?

Looks like some grade A garbage that you got rid of, Mussels.

Yeah, NVBroadcast is an issue bundled like this, since these applications are using their own versions of it

The horror is that you could have multiple versions running at once, even more than i did - iCue, LGHUB, NVbroadcast itself and then whoever else partners with them in the future (Teams? Discord?) all using their own resources, instead of one shared universal copy

Thats the only thing I havent used. I've only used Discord for everything.

That's the part that breaks. You have to install it, before it goes to shit and wont uninstall.

I get the feeling I should say, "Why am not surprised?".

I got all pissed off and posted this because

1. After uninstalling their software, it not just left files behind but they remained active, using the 1GB+ RAM and VRAM per active mic
1a. This of course went really bad with corsair also having it since it was active twice at the same time, exploding the RAM usage

2. Logitechs email support and reddit support, both tried to get me to RMA my Blue Yeti microphone instead of offering any support at all.

I do hate that left behind BS too. Being still active will get me to toss the pc out the window, or go fishing for a week, whichever comes first...

Logitechs email support

Speaking from expereince from 2 keyboards and a mouse ( both since replaced ),I can say that this is not existent, expect long long delays, several weeks, or long enough for warranty to end.

So if you manage to get the Nvcrapia software uninstall without reinstalling windows.... well, I just cheer for ya.

I did, by deleting a folder in system32

Which just screams "user will break windows trying to fix this"

There used to be a program that monitored a programs installation process and kept a separate log. Something like that would still be handy these days.
