[AG-TECH] Vic thoughts

MessageWe were having a similar problem with our display machine (not even
PIG).  We discovered that we only experienced this problem on a single CPU
machine.  As soon as we setup on a dual CPU, the problem went away.  The
single CPU was a P4 1.8GHz, and the first duals we setup without the problem
were P3 600Mhz.  Maybe the code is geared for dual CPUs?

hope it helps,

  To clarify the below, our problem seems to be a CPU utilization one.  With
only a few windows open, or even just one with substantial motion in the
video stream, the CPU time required by OM Vic skyrockets to 100%,
effectively disabling the machine.  In contrast, the v2.8nlsde-2.1.3-1114v
version of vic utilizes the CPU much more efficiently.  Any suggestions on
how to improve this would be appreciated.  I should note that the settings
we are using are h261 compression at 29fps and quality of 1, in case that
affects things.

    We have been doing a lot of work lately with the various versions of the
PIG - vic.exe on Windows 2000/XP.  We have found that when opening more then
4 windows the only version that seems capable of performing exceptionally
well is the v2.8nlsde-2.1.3.-1114 version of vic.  If we use the Open Mash
or the vic.exe (DD or without) off the AG site - the applications run but
seem to hang or skip on a computer when opening more then 4 windows at once.
Has anyone experienced this?  If so, do you have a work around?  We are
using the NVIDIA Quadro4 Video cards with 128MB of Video Memory.

    thanks -
