HP True Graphics HP True Graphics offloads rich multimedia content to the GPU, delivering high-frame-rate images and boosting efficiency. HP True Graphics requires one of the following Citrix environments: ● Citrix XenApp/XenDesktop 7 or newer ● Citrix HDX 3D Pro (not running in Always Lossless mode) HP True Graphics server-side requirements XenApp/XenDesktop The Citrix server must support sending session data in H.264 format. H.264 is enabled by default and is processed using the DeepCompressionV2 encoder, a CPU-based compression algorithm. Only full desktops or non-seamless applications are currently accelerated when using HP True Graphics. Hosted remote applications running in seamless windows do not see benefits from HP True Graphics. See HP True Graphics client-side configuration on page 30 for information on how to force applications to run nonseamlessly by configuring the TWI Mode setting on the thin client. HDX 3D Pro HDX 3D Pro desktops can use the H.264 format and benefit from using HP True Graphics, even if running older versions of XenDesktop. You might want to use HDX 3D Pro to offload the server-side H.264 encoding to the GPU using the DeepCompression encoder. See Citrix documentation for more information. NOTE: HP True Graphics does not provide any performance enhancement if HDX 3D Pro is used with the visual quality set to Always Lossless, because then the graphical information is not sent to the thin client in H.264 format. Verifying server compression options After connecting to a Citrix desktop, use the Citrix HDX Monitor to determine which encoder is being used for the session by examining the information under Graphics > Thinwire Advanced > Component_Encoder. If the value reads DeepCompressionV2Encoder or DeepCompressionEncoder, then the server is properly sending the data in a format that is accelerated by HP True Graphics. NOTE: If legacy graphics are being forced via a server policy, such as CompatibilityEncoder or LegacyEncoder, the server is compressing graphics in a method that is compatible with older versions of Citrix clients and you will not experience enhanced performance from HP True Graphics. HP True Graphics client-side configuration Compression settings H.264 compression must be enabled on the thin client for HP True Graphics to provide any benefits. To enable H.264 compression on the thin client, select the Enable H264 Compression checkbox in the Xen Connection General Settings Manager. Some screen data, such as text, might be sent using methods other than H.264. In general, it is best to keep this feature enabled, but for troubleshooting or specific use cases, the following registry keys can be set to 0 to disable this feature: ● root/ConnectionType/xen/general/enableTextTracking ● root/ConnectionType/xen/general/enableSmallFrames 30 Chapter 6 Citrix connections

rich multimedia content to the GPU, delivering high-frame-rate images and

boosting

eﬃciency.

HP True Graphics requires one of the following Citrix environments:

●

Citrix XenApp/XenDesktop 7 or newer

●

Citrix HDX 3D Pro (not running in

Always Lossless

mode)

HP True Graphics server-side requirements

XenApp/XenDesktop

The Citrix server must support sending session data in H.264 format. H.264 is enabled by default and is

processed using the DeepCompressionV2 encoder, a CPU-based compression algorithm.

Only full desktops or non-seamless applications are currently accelerated when using HP True Graphics.

Hosted remote applications running in seamless windows do not see

beneﬁts

from HP True Graphics. See

True Graphics client-side

conﬁguration

on page

for information on how to force applications to run non-

seamlessly by

conﬁguring

the

TWI Mode

setting on the thin client.

HDX 3D Pro

HDX 3D Pro desktops can use the H.264 format and

beneﬁt

from using HP True Graphics, even if running older

versions of XenDesktop. You might want to use HDX 3D Pro to

oﬄoad

the server-side H.264 encoding to the

GPU using the DeepCompression encoder. See Citrix documentation for more information.

NOTE:

HP True Graphics does not provide any performance enhancement if HDX 3D Pro is used with the

visual quality set to

Always Lossless

, because then the graphical information is not sent to the thin client in

H.264 format.

Verifying server compression options

After connecting to a Citrix desktop, use the Citrix HDX Monitor to determine which encoder is being used for

the session by examining the information under

Graphics > Thinwire Advanced > Component_Encoder

. If the

value reads

DeepCompressionV2Encoder

DeepCompressionEncoder

, then the server is properly sending

the data in a format that is accelerated by HP True Graphics.

NOTE:

If legacy graphics are being forced via a server policy, such as CompatibilityEncoder or

LegacyEncoder, the server is compressing graphics in a method that is compatible with older versions of Citrix

clients and you will not experience enhanced performance from HP True Graphics.

HP True Graphics client-side

conﬁguration

Compression settings

H.264 compression must be enabled on the thin client for HP True Graphics to provide any

beneﬁts.

To enable

H.264 compression on the thin client, select the

Enable H264 Compression

checkbox in the Xen Connection

General Settings Manager.

Some screen data, such as text, might be sent using methods other than H.264. In general, it is best to keep

this feature enabled, but for troubleshooting or

speciﬁc

use cases, the following registry keys can be set to

to disable this feature:

●

root/ConnectionType/xen/general/enableTextTracking

●
