PixelSearch Accuracy

Hello everyone.

I've been using the pixelsearch function like this:

Do
	  PixelSearch(StartX,StartY,EndX,EndY,Color)
Until @error = False

It's only searching for one pixel at a time and I have aero disabled. I'm not having any problems, it's just that sometimes it takes longer for AutoIt to react to success than other times.

For instance, if I time how long it takes for PixelSearch to complete it sometimes varies from 25ms - 50ms. Is there a better way to make a pixelsearch loop or a better function to achieve accuracy? I'm looking for accuracy from about 25ms - 30ms (+/- 5ms. I don't really care how long it takes. It could take 500ms, and I wouldn't care, but I need it to be accurate. I don't care about speed.)

Thanks!
