Key Resolved Issues


Key Known Limitations

 Reports of ESXi purple screen (PSOD) in certain circumstances are under investigation. 

 Reports of blinking or blank screens are under investigation.

10664, 10625 - Caching is not supported on multi-display PCoIP sessions. When more than one display is connected to a VM, the caching is not working, meaning bandwidth utilization will stay the same as with APEX 2800 drivers 2.2.

6622  - Lower frame rates when using a VMware View software client. Occasionally, with certain workload types, the software client output frame rate will be slightly lower when a display is being processed by APEX. Teradici PCoIP zero clients are unaffected.
In some occasions, you might experience a reduction of frame per seconds in a GPU Pass through environment (vDGA).

The above known issues are under investigation. Please subscribe to this knowledge base item to receive updates.
