PCoIP Ultra

The Standard Agent for Linux provides support for PCoIP Ultra, the latest protocol enhancements from Teradici. PCoIP Ultra is optimized for truly lossless support with bit-exact color accuracy and preservation of content detail at the highest frame rates.

PCoIP Ultra protocol enhancements propels our industry-recognized performance into the future of remote computing, with faster, more interactive experience for users of remote workstations working with high-resolution content.

PCoIP Ultra enhancements are disabled by default. You must enable them manually.

PCoIP Ultra is appropriate for specific use cases

For most users, the default PCoIP protocol will provide the best possible experience. Carefully review the recommended use cases in the next section to determine whether you should enable it.

For additional detail on PCoIP Ultra technical requirements for various use cases and troubleshooting steps, refer to KB 2109: PCoIP Ultra Troubleshooting.

When to Enable PCoIP Ultra

In release 20.01, PCoIP Ultra supports the following use cases:

  • Users requiring CPU-optimized delivery of 4K UHD, high-framerate video playback.

  • Efficient scaling across multicore CPUs, leveraging AVX2 instruction sets.

For all other scenarios, Teradici recommends that you leave PCoIP Ultra disabled.

Requirements

To take advantage of PCoIP Ultra, you need:

  • A PCoIP agent (any type), 20.01 or later

  • A PCoIP Software Client (any type), 20.01 or later

    PCoIP Tera2 Zero Clients are not supported

    PCoIP Ultra is supported by PCoIP Software Clients only. PCoIP Tera2 Zero Clients cannot use PCoIP Ultra.

  • The CPUs on both the agent and the client machines must support the AVX2 instruction set.

Enabling PCoIP Ultra

To enable PCoIP Ultra features, turn on the following configuration settings in the pcoip-agent.conf configuration file:

All PCoIP Ultra settings take effect on the next PCoIP session. No configuration is required on the PCoIP Software Client.

Setting configuration values

If you don't know how to set PCoIP agent configuration values, refer to Configuring the Standard Agent for Linux.
