I am using DirectRT to set up an experiment that involves flashing
images at a fast rate. I want to flash two images for 50 msec each with no gap between them. But it takes 20 msec to load the images so I get the following timeline:

First image (50ms)
Black screen while loading (20ms)
Second image(50 ms)

Is there any way to have the second image appear immediately by perhaps loading it while the first image is showing?
