Craig, We took our most complicated effect, the orientation effect which allows you to adjust the rotation of an image in the X, Y and Z axes (amongst other things) and we applied it to a 640×480 image. I should explain that we have more than one type of orientation effect and this one is the slow one. We spent 4 man months developing it and we made it as perfect as possible. It fully antialiases the image and field renders the result for perfect subpixel positioning and rotating. Our other effects take nowhere near as long and the times should be taken as an indication of the improvement of speed rather than as how long something takes. I will perform some tests using the crossfade to find out how long it takes. To put it into perspective a crossfade on a Windows 3.1 machine normally takes 2 seconds. Here are the figures: All machines have 32 MB RAM. Windows 3.1 Pentium 90 44secs Windows NT Pentium 90 15secs Windows NT DEC Alpha 150 MHz 7.5secs Windows NT IBM PowerPC 7.5secs Windows NT Aspen Alpine 275 MHz 4secs More RAM will make things faster – higher clock speed has a significant affect.
