I have Rhino V4 on Windows 7 Professional. I just reloaded it recently onto a replacement SSD drive. Now when I switch in and out of the working windows (perspective, front , side, top) which ever window I’ve been in stays functional and all the others go black. When I right click into a new window it will come back but the others stay black.
Wait we are only halfway there.
What that setting does is disable your GeForce card in Rhino. Now most display related calculations are done on the CPU and you are not profiting of its speed.
Again make really sure you have the latest drivers for that card installed and enable the hardware acceleration again. It should work or something else is wrong.
