O2's general performance varies slightly depending on the display format used,
but not by much. This happens because as more bandwidth between main RAM
and MRE is used for the video display, less is available between main RAM and
everything else. In the extreme case, comparing VGA 16/16 60Hz to 1280x1024
32/32 72Hz, the drop in Stream performance is about 10% (I don't know whether
this is indicative of other tasks).
But going from 1280x1024 32/32 72Hz to 1600x1024 32/32 60Hz would probably
only decrease Stream performance by maybe 4%. You could easily counter any
perceived performance drop by enhancing some other aspect of the system, eg. use
a 15k rpm system disk (well worth it!) or install a better CPU (switch from R5K/200
to R10K/195, almost 100% speedup for many tasks).
One caveat btw: when using Effect/Flint/Flame/etc., isn't the display supposed to
run at the same Hz as the video being used? Ok for NTSC I suppose, the 1600SW
can run at 60Hz. But what about PAL? Can the 1600SW operate at 50Hz?
To be honest though, doing that kind of video with a Discreet app, I'd rather
just be using huge CRT or modern TFT. And there's always the custom O2 video
mode which is 1400x1024 or something.
