The main issue with my setup is that VMware or Windows 11 (my host OS) can't use the GPU when rendering the UI of the VM (I'm not sure if VMware or MS is to be blamed or both) despite having a discrete GPU card installed.
The rendering of the image must all be done by the CPU, which requires a lot of RAM.
After switching to 3 x 4K monitors, the VM requires 62GB of RAM to be able to run on full screen on all monitors (63720 MB to be precise). I recall that I somehow managed to get it working while "only" using around 32GB, but it became unstable. 62GB is the sweet spot where everything runs smoothly. Haven't tried to adjust the settings in years. It was a pain to get working in the first place with 4k monitors, and since I have 256 GB installed, I just left the settings as they are.
At next motherboard upgrade I might revisit, but I think that VmWare still can't take advantages of the host GPU in this regard so I expect the RAM requirement to stay.
Some computer problems can be solved by throwing hardware at it. This is one of those. Give VMware and Windows an obscene amount of RAM, and you can have Teams running smoothly and flawlessly inside a VM on a Windows Client Host in 4K.
