- Hey, I'm not the one who wrote what you are responding to, but I'll be
- happy to reply. :-) I agree that the 8bit WB is as fast as a 4bit WB
- on the A3000, but that isn't exactly snappy. :-)
-
- I ran a 3bit WB on my A3000 and have been running a 6bit WB on my A4000.
- The graphics performance is as good or better and the text scrolling is
- actually a bit faster. For comparison, the 8bit WB in dblNTSC high res
- no flicker with 676x467 res is comparable to the 640x480 8bit mode on
- my 486-50DX/ET4000 at work running Windows 3.1. In terms of scrolling,
- the A4000 wins, but the 486 does better with some screen redraws. To
- explain a bit further, both machines are finished redrawing at about the
- same time, but the A4000 exhibits "bitplane flicker" during redraws.

- I have to agree here. I've been using MultiView extensively with all sorts
- of pictures, sound, text files, and AmigaGuide files without a single crash.
