- Very simple. Compared to 320x200x4 (bitplanes), 640x400x4 is four times as
- much data. Also, since you have to transfer 320 bytes instead of 160 in the
- 64 msec (A3000 w/ de-interlacer) or 32 msec (A4000 with 31kHz modes) it takes
- to draw one line to the screen, hires modes eat a lot of chipmem bandwidth.
- In fact, on A3000 it would take all the chipmem bus (leaving processor access
- only between lines and frames). So, using hires would mean that the program
- would have much less time to transfer a lot more data, so the frame rate would
- drop. Simple as that.
- I'd take high frame rate over high resolution in animation any time. Of course,
- if you could get both, it would be great, but...
