Blast Extreme is a high performance display protocol. The protocol contains both WAN optimization and support for 3D graphics, resulting in a far superior end user experience when compared to RDP.
To use the Blast Extreme protocol:
Each virtual desktop must have the latest versions of the Horizon Agent and DaaS Agent installed.
End users must have the VMware Horizon Client installed on their end point device.
Blast Extreme is the default protocol for Native Clients in the pool settings.
