Task workers mostly need Soft 3D, a software-based 3D renderer good for less graphics-intensive applications. They do not require, or get a noticeable advantage from, hardware-based 3D acceleration. Soft 3D is a standard component of Horizon.
Office workers and executives come into this profile, mostly using applications such as Microsoft Office, Adobe Photoshop, and other non-specialized end-user applications. A Virtual Shared Graphics Acceleration (vSGA) solution can optimize performance for this use case by providing high levels of consolidation of users across GPUs. vSGA does not provide a broad range of graphics API support, as it is always better to consider a vGPU-based solution for knowledge workers.
