Issue:
3D client Very Slow using VDI (Virtual Desktop Infrastructure)

 
Environment:
VI/VDC 5.x
Cause:
VDI usually delivers poor performances for many graphics intensive applications. This is because VDI uses shared CPU to emulate GPU operations. Graphics operations, especially 3D graphics operations are very demanding. Every 3D object manipulation or every 3D view angle change requires massive numbers of parallel processing on 3D matrix, texture, lighting effect, etc. Such demanding processing is difficult for the VDI shared CPU to emulate and still deliver satisfactory visual experience to end users. In recent years, companies, such as Nividia, who has technologies to offload graphics operations from CPU to real GPU: https://www.nvidia.com/object/enterprise-virtualization-old.html
Resolution:
To increase VDC 3D Client performance, we recommend to use the Graphics Accelerated Visual Desktop Infrastructure.

he latest version of VDC has a Web interface that provides almost all of the functions that are available in the 3D client. This web interface is 2D and doesn't have the intense graphics that are in the 3D client.
