If a customer has a graphics card which is ATI Or NVIDIA as recommended by Cisco, what are the maximum Live Streams can you have on a PC with 4 cores, 3GB RAM through VSOM? I have seen this on one occasion where the client PC can only display 3 HD Streams at any one time on ONE client PC thus failing connections to the fourth HD Stream? How can we measure what the maximum streams the client can handle and what factors determine this? I look forward to your reply. I have tried the workstation profiler however this does not have a saved profile for HD Cameras.
