I changed the 0 and 1 values back and forth and ran the script several times, however it looks the same with one /drawscroll or multiple /drawscrolls. I wonder whether the behaviour might be dependent on the Windows version or perhaps the graphics card. Which version of Windows are you using?
As for the timer, I'll be changing it in the next version so that the ordering only works when a switch is specified, so it will return back to it's normal speed. I also found out the reason why the /draw* commands were slower and that has been resolved as well :-)
