The kyro 2 is not the best video card for use in 3dsmax unfortunately, I think that due to the tile rendering process hiding the the rendered image the program gets a bit 'confused'. I would guess that performance should be on par with a tnt2 if the Opengl drivers are any good, unfortunately this doesnt seem so. Hercules dont recommend the Kyro II for 3d rendering programs might be worth posting on there forum.
