I used the configuration of Simplify3d V4.1.2 via Remote Desktop on vm. It was working well over several years.
Now the Os of the vm was upgraded from 20H1 to 21H1 with effect Simplify3d is started and only the frame is visible.
Running the console mode with display drivers "AMD MxGPU,WMware SVGA 3D" is working.
via Remote Desktop there is one more display drive "Microsoft remote desktop"
What can I without stepping backward?
