OK I've reworked a basic Build built with the latest Unity Engine so it might work better?
Let me know how it goes and what graphics card are you using?
I just checked, and my computer seems to have two installed: AMD Radeon(TM) Graphics, and NVIDIA GeForce GTX 1660 Ti. I'm not sure which is actually doing the work, but the NVIDIA one has a more recent install date, so I'm going to guess that one.
