Finally, now Teradici has found a solution to my (and others) problems regarding laggy windows compared to TERA1 chipsets!
SCENARIO:
While there are many factors that determine desktop performance (for a list see General Troubleshooting Steps - Poor Performance on Virtual Desktops (15134-932)), lower performance of window dragging may be observed in the following scenario:
- VMware Horizon View 5.2 virtual desktop
- APEX 2800 is not installed, or hardware acceleration is not enabled for the VM
- Tera2 dual display zero clients running firmware 4.1.0
In some cases there may be PCoIP zero client log entries such as:LVL:1 RC:-500 MGMT_IMG :(pkt_rx_resource_check): Insufficient imaging resources. Dropping imaging data.Workaround:This issue will be addressed in an upcoming firmware release. To workaround, determine if the color codec is the issue, set the following registry key as shown below to see if the problem goes away.pcoip.enable_new_color_coding 0 The registry key is a DWORD value.Note: Ensure you have the necessary backups in place and are familiar with changing the registry before proceeding.To change the registry key:
- Click the Windows Start button and type regedit in Search programs and files.
- Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Teradici\PCoIP\pcoip_admin.
(If you do not see the 'Teradici' key and subsequent keys, you will have to create them)- Add new DWORD Value and name it pcoip.enable_new_color_coding.
- Give this a Value data of 00000000 and click OK.
- Disconnect/Reconnect your PCoIP session for the change to take effect.
In my case I also had to disable Image Caching as well, same location: pcoip.enable_temporal_image_cachingREG.DWORD 0
Now the TERA2 behaves and works just as good as the TERA1 does!
