VMware Horizon 7.10 and newer versions support a new dynamic encoder called the Switch encoder when using the BLAST display protocol. Dell Technologies has validated this new capability and recommends enabling it. The new feature provides the capability for the display protocol to dynamically and seamlessly switch to the best codec based on user workload patterns. When using an NVIDIA vGPU, this feature is disabled and the NVENC H.264 hardware encoders are used to offload the encoding of the display protocol from the CPU.

This feature can be enabled by using the registry or through the Dynamic Environment Manager. For more information on how to enable the Switch encoder, see the Horizon 7.10 release notes.
