PCoIP Ultra¶
The PCoIP Client 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 controlled on the PCoIP Agent. There is no configuration required on the PCoIP Client.
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¶
PCoIP Ultra is apporpriate for users with the following requirements:
Auto Offload: Achieves the best balance between color accuracy and network efficiency. This setting is appropriate for work-from-home or WAN content creators who require optimized delivery of high resolution content, including video playback, while still achieving build-to-lossless color accuracy.
CPU Offload: Provides efficient scaling across multicore CPUs, leveraging AVX2 instruction sets. Appropriate for users that require CPU-optimized delivery of 4K UHD, high-framerate video playback and build-to-lossless color accuracy. It is also useful when GPU encoding resources must be reserved for video encoding applications, typically in LAN environments.
GPU optimization Offload: PCoIP encoding is always offloaded to a GPU. Appropriate for users who demand the highest possible CPU efficiency.
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), 21.03 or later
-
A PCoIP Software Client (any type), 21.03 or later
-
The CPUs on both the agent and the client machines must support the AVX2 instruction set.
Enabling PCoIP Ultra¶
In order to enable PCoIP Ultra features you must turn on GPO variables in the PCoIP Agent. For information on enabling this with Linux, see Enabling PCoIP Ultra for Linux. For information on enabling this with Windows, see Enabling PCoIP Ultra for Windows.
Auto-Offload with PCoIP Ultra¶
The auto-offload feature with PCoIP Ultra enables users to allow PCoIP Ultra to select the best protocol, whether that is CPU or GPU, based on display rate change. CPU Offload is used by default to provide the best image fidelity, GPU Offload is used during periods of high display activity to provide improved frame rates and bandwidth optimization. This setting is only effective if the remote host and client endpoints are capable of both CPU and GPU Offload. You can select this option when you are enabling PCoIP Ultra.
For information on how to do this, see PCoIP Ultra - Windows, and PCoIP Ultra - Linux.
PCoIP Codec Indicator¶
When enabling PCoIP Ultra there will be an onscreen indicator at the bottom left corner of the screen. PCoIP Ultra CPU optimization is indicated with a dark blue dot. PCoIP Ultra GPU optimization is indicated by a magenta dot. To disable this codec indicator create the following registry key and set to 0: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Teradici\PCoIP\pcoip_admin_defaults\ pcoip.codec_indicator (DWORD)
