SCANLINE EFFECTS...

[Ancalimon]

As we all know, there is a scanline that moves in the monitor and each time it passes the whole screen, display is updated.

Problem is, this scanline effects the moving objects on screen: Like mouse pointer, solid moving windows, ... everthing.

On AGA usually scanline movement is timed so good that it seems to stay in one place not effecting the movement of objects, reulting in very smooth animation.

If scanline movement could be kept from moving rapidly on screen and stayed at the bottom of screen, this would not happen on RTG screens.

Here if I set my AGA output to a 60hz one, and also set my CGX refresh rate to 60hz and do a bit finetuning with CGXMODE, I get that smoothness again.

I didn't mean to say that.
If you stop scanline movement I know there will be no screen update. What i mean is that move the scanline at a rate so that it looks like its staying at one position. If you use a video camera on your monitor while its running you'll see the scanline clearly. By doing those things I mentioned in my earlier post, the camera will not detect the scanline now. And also movement of mouse pointer, windows, and everthing else have become smooth. Thay are not interrupted by the scanline. The scanline still exists I know it but it already reches the bottom of the screen while a new frame is sent to the monitor resulting in smoother animation.
