Do I need both DirectRT and MediaLab?

Take a look at this page of the DirectRT manual that has more information about timing in DirectRT: http://www.empirisoft.com/directrt/h...y_concepts.htm

Jason, Thanks. I already saw that page, and I know that *DirectRT* achieves millisecond-quality timing by means of DirectX. But that's not my question here. And I already know that *MediaLab* (as opposed to DirectRT) does *not* provide millisecond accuracy. To repeat, I would like some quantitative estimate of what kind of timing accuracy we might expect with MediaLab. Using *MediaLab* (as opposed to DirectRT), could we expect timing accuracy of 100 ms? 10 ms? 1 s? 5 s? 5 min? Or are "all bets off" when it comes to timing with MediaLab?

In particular, I am curious about timing accuracy for measuring responses (as opposed to timing accuracy for the presentation of stimuli).

Thanks.
