Ubuntu on Hyper-V sluggish/slow UI experience

Ubuntu 20.04 LTS installed with Hyper-V Manager. I have assigned it 4 processor cores and 12GBs of RAM. I have run through several forums and tutorials and I haven’t found any solution that would actually help with the issue. The performance is so sluggish, it’s making usage of the VM unbearable. I’d love things to run smoothly – moving the cursor, opening windows, scrolling etc.

i-7 8700K, 32GB, Intel UHD Graphics 630, SSD

I’d appreciate any help.
