Did you use acceleratedRendering? Set it to true and set the layermode
of each moving object to dynamic. I'd be curious to see if there's a
difference.
Hadn't tried those until now. There is a difference - but not the kind
I'd hoped for :-)
Full script is below with detailed time, but the summary is:
- acceleratedRendering made things much worse (50% to 90% slower)
- dynamic layerMode made things a little bit better (5% to 15%).
If the circle was moving over a plain background, improvement was only
5%-ish, while if moving over multiple other shapes, it gave a better
improvement.
Here's the full snippet of the script involved (other cases obvious :-)
set the acceleratedRendering of this stack to false
set the layermode of grc "g1" to "static"
repeat 3 times
put 100,400 into tmp
put the millisecs into tim1
repeat 100 times
add 1 to item 1 of tmp
set the loc of grc "g1" to tmp
wait 0 with messages
end repeat
put the acceleratedRendering of this stack && \
the layermode of grc "g1" \
&& the millisecs-tim1 &CR after gLog
end repeat
put CR after gLog
Here are the times for each of the cases, moving 100 times
false static 192
false static 154
false static 155
true static 285
true static 332
true static 249
true dynamic 265
true dynamic 255
true dynamic 309
false dynamic 131
false dynamic 134
false dynamic 149
