Well, I haven't seen this question before, so I hope someone
can help me with it.

I am evaluating the video performance of several machines.  This includes
timing the video painting time for an entire screen of characters, in
different resolutions.

The problem is, with the clock tick being 18.2 times/second, my granularity
is about 55 milliseconds.  In the faster machines the paint times are less
than this, so i do not get an accurate measurement.  In using 
GetCurrentTime() before and after the paint, the difference will be 0!

Is there any way around this?  Any ideas would be appreciated.

Thanks,
