John,
I was on the phone with Keith from Right Answers today — boy is the guy
talkative! Now I know why it took me all day to get through B^D
Anyway, we did a test on his 3000 right over the phone. He moved a
hi-res picture from Fast RAM to Chip 100 times. The process took 28
seconds, which is darn close to the 3.8 frames/second I got using ANIM!
However, it turned out he was moving true hi-res frames, i.e. hi-res on
both directions — 352 by 440. This means twice the frame rate at vertical
resolutions of 220. In addition, he has both 32- and 16-bit memory in his
machine, so we can't tell for sure if the source frame was coming out of
32-bit wide RAM or not. If it was in 16-bit wide RAM, then speed on my
machine (100% Static Column 32-bit RAM) would be higher again, although not
by a factor of two. (Source would be twice as fast, but destination would
be just as slow –> Chip RAM)
I take it to mean that I can move at least 8 frames/second into Chip
RAM. That's getting more acceptable. I also like the control I'd get with
The Director, for example blitting quarter-frame sized images into a
picture frame or TV screen. This is what you're doing right now, actually.
I'll be ordering The Director 2.0 this week.
