[QGIS-Developer] QGIS 3D and Graphics Card Requirements

[C Hamilton]

I just noticed this thread. For what it's worth, many of my users are
running QGIS on virtual machines. I don't advertise the QGIS 3D
capabilities because it performs badly in the VM environment or not at all.
Even on my personal laptop which is a fast machine with a decent video
card, but does not have a high end graphics card, I find the 3D
performance to be slow enough that I don't use it. I have played around a
little bit with Blender 3D and it wasn't slow.
