I recently built a new workstation to run Autocad 2017. It has an Intel I7-6700K 4.0 Ghz cpu, Kingston 32 GB memory on a MSI Z170A m/b running Windows 10 Pro.
I ran a rendering base test with the example house in Revit; that took 31 minutes. I then installed a Quadro K4000 graphics card with 3gb memory on it, loaded the drivers from Nvidia's site and reran the test. The time was the same, and the Intel CPU was maxed out during that period.
I was expecting some difference. What am I missing?
