The 4D viewer in Vision4D and the VR viewer in VisionVR are both highly dependent on access to the graphics hardware to perform. However, graphics support on VMs is somewhat patchy, with different virtualization platforms having a variety of support levels for a variety of device drivers. Problems with 3D rendering on VMs are therefore difficult to pin down and fix and are mostly dependent not on arivis support, but on the specific vendors for your GPU and virtualization software. If you are experiencing problems with GPUs on VMs arivis will try and support you as far as we can, but note that we may be limited in our ability to help by the the specific configuration of your system.
