about your hardware.
I'm afraid that's... highly questionable. The more video streams (etc.)
that are visible the smoother you want the overall presentation to be:
the human brain is /very/ sensitive to small timing differences. In
addition, there are standards for e.g. flashing indicators in
safety-critical applications which are specified with much finer
resolution than 100 mSec.
So a 10Hz update is totally out of the question these days: 100Hz would
be more realistic.
But I still don't entirely agree with MichaelS: just because something
is highly desirable doesn't mean it's attainable, and some sort of
double-buffering would probably be a good compromise.
