MS Frame Duration Keyword

<MSFrameDuration N>
<msfd N>
<ms% N>
<%ms N>

    % switch alternative. Unlike the traditional % switch this keyword specifies a frame duration in milliseconds. On systems with high performance counters DMDX knows the retrace interval to within a few microseconds and this can be used to calculate frame durations in milliseconds. The result is always rounded up.

    NOTE:- this is not an F parameter (as opposed to switch) replacement.

    <%ms> is provided for one of two situations. Either you don't care about precise tachistoscopic presentations (for example you are specifying frame durations that are multiple seconds long) and you don't really want to be bothered figuring out just how many hundred ticks that's going to be, or you want an item file to work on multiple machines regardless of their refresh rates. If you are going to use multiple refresh rates then %ms is no more accurate than having individual item files for each machine.
