8 years ago I bought a Quadro 2000 (Fermi) and I disappointed when drivers were not available.
Now, I would like to buy Nvidia Quadro P4000 and I see that there is no support to Windows 10.. WTF!!!

I can understand that there is no still support for AutoCAD 2019..... but W10?
More than 700 $......... It looks like a scam.
AutoCAD, like a lot of engineering applications, used to be OpenGL only. Those were the only cards which had the horsepower to do what was necessary. Now, pretty much everything display oriented has moved to DirectX. There's a few which still use OpenGL, either because they're supported on multiple operating systems (no DirectX on Mac, but then again OpenGL may not be getting updated on that either in the near future) or because they're using it for GPU-compute purposes.
The old "normal" drivers worked with all cards, even the old ones or new ones with limited OpenGL support; the "performance" drivers took advantage of the full OpenGL features in the workstation cards. Now that the display system is DirectX there is no baseline/performance workaround to deal with.
TL;DR version: don't worry about the legacy "performance" drivers. There isn't any purpose to them now.
This is the driver I'm using at the moment. It works fine. I'd suggest downloading the most recent from Nvidia. As others have mentioned. The Performance Drivers dissipated quite a while ago.
The P4000 is a very good card. It will even handle Leica Cyclone which is harder on the graphics cards than Civil 3D.
