Why do large vector shapes add delay to Keynote cues?

Hello, we are doing a multiscreen Keynote 6 presentation using a 2012 MacPro tower 12 core 24g ram with an ATI 5770 and a matrox triplehead to go Digital edition. When we use any large shapes created in keynote, it adds almost a 3 second delay to every cue on that slide. If we change the Vector shapes to PNG's, the delay disappears. If we eliminate the Presenter View monitor, the delay disappears. Even if the shapes are static and not even visible on the stage they add a delay.

The Presentation size is 720x2160 and the vectors are 2160x2650. Does anyone know why the Vector shapes would add such a delay when PNG's do not??

According to your post, you have a long thin vertical slide with shapes larger than the slide.

I have no difficulty playing a 50 slide presentation with these dimensions.

Vector files, either created in Keynote or imported, use a lot more processing power than simple bit-map images (like png or jpg). Especially very complex vector files. It is best for widescreen shows to use bit-mapped images that are sized correctly (so Keynote doesn't have to scale them.

When using the presenter display, Keynote has to render current and next slide previews before going to another slide, that was causing your additional slowness. I've run some presentations with presenter display off for that reason, especially in the case of quicktime files "hiccuping" right after they start.

BTW, it is standard practice to always put the screen width first, then the hight. So your screen size would be written as "2160x720"
