I cannot believe this is a problem still under Parallels 10... !!! the CAD apps cannot realize the potential of the Quadro 4000 card which is NOT new in the market. I tried to installl the approved NVIDIA drivers 331.82 or 320.78 and they stop with : "NVIDIA Installer cannot continue" ...This graphics driver could not find compatible graphics hardware. How long we have to wait for Parallels Inc. to fix this serious issue ???? Veeery dissapointed.
