VDI using vWorkspace with vGPU for Autocad

Hi, i need support with the next situation.

I'm installing vWorkspace to create virtual machine with vGPU to use Autocad design software.
This is the configuration

Hyper-V Server
Dell PowerEdge R270
Windows Server 2012 R2 Standard
112GB RAM
Intel Xeon CPU E5-2640 2.5Ghz
NVIDIA GRID K1
Driver 321.01 (Latest driver)
Driver Model: WDDM 1.3
DirectX 11

vWorkspace Server
Virtual Machine
WIndows Server 2012 R2 Standard
8 GB RAM
4 Virtual CPUs
Quest vWorkspace x64 8.0.306.1462

Hyper-V Settings Physical GPUs is OK

I create a computer group "Design" with two computer with Standard Video Adapter.
The configuration template for Design Computer Group is:

-2 Virtual CPUs

-4GB RAM
-Windows 7 Enterprise SP1 x64
-All Windows Updates.
-Latest Integration Services.
-All vWorkspace requirements: PNTools, Domain Joined, InstantProvisioning,etc.
-Include Autodesk Autocad 2014.
I add a Microsoft RemoteFX vGPU to one computer "Design001".
I leave Design002 with the Standard Video Adapter.

After a lot of tests , i not obtain difference of performance between the two VDI.
And the graphics in Autocad are very limited.

I wonder if something is missing in my setup and if this configuration is supported.
