Minecraft Bedrock does not properly aquire memory (RAM OR VRAM) for UHD texture packs. I have 64 GB of Ram and 11 GB of VRAM. I am getting a low memory reduced resolution notice with a utilization or 2.5 Gb of RAM and 0.277 Gb of VRAM. I have 56 Gb of ram free qnd and 10 Gb of VRAM free. There is no available solutions on the forums. If necessary I can attach the files.

Not sure what other drivers you would need.
This is the biggest pack I am trying to use though I have the same issue with smaller packs as well or just combinations over a certain file size.

problem persists with a 3090 GPU.
Actually no, on further investigation that doesn't seem to be the problem. Your pack is only 1.25 GB after importing, and I don't think Minecraft copies it anywhere on disk when it's used through global resources. The issue here seems to be an arbitrary size limit for resources the game will actually load into RAM.
It is kind of bizarre that the game reduces 16 x 16 textures to 8 x 8 to compensate for using too much RAM on 4k textures.
(I will mention too that your pack is not constructed in the preferred way--it includes copies of all of the vanilla textures that you are not replacing. Those should deleted (unless you're just using them as placeholders for work-in-progress). However, that does affect the issue reported here.)
I believe they are place holders. I did not make this pack so I am not 100% sure.
It appears to be the same issue with a smaller pack.
Thank you for your report!
