Weird, I pass through a dGPU for work VM sometimes on Win10/11 @ 2K without much memory usage except I don't use MSTeams but it doesn't surprise me that it needs 60GB RAM nowadays.
I'm jealous of your system's 256GB, my memory controller looks to max at 128GB but it's kinda old now (DDR4).
As I understand it, when connecting to the vm through the VMware console viewer, since the desktop image of the remote computer is rendered within a VMware process, which is CPU-bound, only the CPU can handle this task.
Spanning multiple 4K monitors demands significant RAM to handle the large aggregate framebuffer size and the associated overhead for rendering and display synchronization.
