Media Encoder Barely Using Any CPU or GPU Resources -- Please Help!

[GOD-sSs-END]

My System:

Windows 11

i9 13900K (24 core)

128 Gigs of RAM (4000+ hz)

EVGA FTW 3090 (24 Gig VRAM)

M.2 across the board (working/rendering on separate drives)

My Issue:

I'm rendering a high-settings video (60 VRB, 2 pass at 4K). Yes, this is a lot, but my machine should handle it. Yet, while rendering on software only, my machine is using only 15 to 20 percent CPU and no GPU. When I switch to GPU acceleration, I'm still using roughly 15 eprcent CPU, but only 10 to 15 percent GPU.

What's wrong here, and how do I fix it?

Thank you so much.

ANOTHER NOTE:

Out of the 128 Gigs of RAM, Media Encoder is only using 24 Gig.

The usage of CPU vs. GPU is highly dependent on the formats and filters being used. You can manage how much memory AME uses under Preferences > Memory. Hope this helps.

Great "correct" answer. Thanks for marking it for me as "correct." I took the liberty to unmark it, because I know how to change the preferences in these programs. They've been set to 104 Gigs with 24 Gigs for background apps for years! That is not in fact the answer.

I've also read a number of posts on how to fix this regardless of "correct" settings. One post in particular mentions opening Media Encoder on its own, with no other Adobe apps open, and Media Encoder will naturally use the 104 Gigs over the 24 Gigs, because AME is then prioritized as the primary app instead of a background app. This, too, was not correct -- i.e., it is not in fact the answer.

Any other ideas?

BTW, if I simply render the video via Premiere Pro, the render finishes in about 5 hours. Via Media Encoder (same RAM settings), it takes 165 hours. I found others in this very forum asking this same exact thing but getting only similarly dead ends for answers.

Sorry for jumping to conclusions too early here.
Is this a new issue? Did AME use more memory before on your machine?
