As vertex animation is not currently supported I am facing a choice: I could animate the vertices or animate the uv ( in my specific case, the result would be more or less identical).
Maybe I should be aware of some greater performance gain with one of two, maybe it's quicker for the engine to recompute vertices than uv.
Any insight would be greatly appreciated.
I am targeting webplayer and iPad, maybe they have different performance in that regard.

I would guess that uv's would be a little faster, because geometry would not be changing, so z-buffering would not change (due to uv changing) and other visibility issues would be constant and so forth. Maybe this would only be a savings (if it is at all) when nothing is 'moving' on scene (except your uv's).
