*Andrew*, you will be interested in reading this!
*Andrea*, if you have time, can you confirm?
*Ben*, you will not believe this!?
even simple transitions like dissolve cause the framerate to go anywhere

It took at least 25 builds on GG's systems to reach the following
conclusion (luckily his computer is fast).
* OPTIMIZATION levels are important !!*
The good news is that the slowdown in transitions was only affecting you
go-getters who do your own builds as a developer. Most likely you were
using the following as suggested in the Features5 manual:
CFLAGS=-ggdb make -j8 rebuild_all
CFLAGS=”-O2 -ggdb” make -j8 rebuild_all
And modify -j8 to better reflect the number of CPUs + a little more on your
computer. I will change the manual.
If this does NOT solve the problem on your computer, let use know and thank
you in advance. gg/Phyllis
