Alberto, I don't really know.To really find out we would have to study the PICT.FLTR code. The documentation says "PIC2 is used for a field that is buffered in an offscreen GWorld. The PICT filter builds the picture faster, but the PIC2 version scrolls complex graphics more smoothly.", so that is probably the best answer until someone investigates further.
