Results (DirectX): AutoCAD 2013 And Inventor
It doesn’t really look like the switch from OpenGL to DirectX is becoming a trend, since Autodesk is the only major company making this drastic change. Of course, the advantage of DirectX for end-users is that they can do without specialized workstation cards, so long as they’re willing to forgo the drivers optimized for specific applications, greater compute performance, and so on. DirectX’s disadvantage is its use of single-precision coordinates, which can easily lead to display errors in complex models, resulting in things like the feared push-through effect of surfaces right behind another surface.
Nvidia's GeForce GTX 780 Ti is the company's fastest consumer graphics card in this benchmark, and it rules supreme in the Cadalyst 3D suite. However, the GK110-based board does succumb to the latest Hawaii-based Radeon R9s in Inventor.
