Ilya, Here's an email exchange I had with PNY:
Using Windows 8 64 Bit. I just bought a Quadro K2000D for running AutoCAD 2014. Are you able to tell me if/when the mini-driver will be updated so that the maximum performance of the Kepler card can be achieved with AutoCAD? According to the following review of the K5000, the lack of a mini-driver update is keeping AutoCAD users from maximum performance with Quadro Kepler cards: http://www.xbitlabs.com/a.../nvidia-quadro-k5000.html
I think you may have it in reverse. Autodesk must update their application to support the Kepler architecture, just as other software developers must do the same thing (Adobe, etc.). If their application does not contain the code required to drive the GPU, no driver update is going to “fix” that problem.
Unfortunately, I'm not smart enough to know who is right - you or the PNY Tech. You say that nVidia is responsible for updating the mini-driver, but he's saying it's up to AutoCAD.
So, I guess in the end, it'll probably never be done.
