I have noticed that with Snow Leopard performance suffers with dual monitors. Animations like dashboard and expose are more sluggish when using dual monitors for some reason (note this is not because of having to drive more pixels. I'll have perfectly smooth animations with a single 2560x1440 monitor, but sluggishness with two 1680x1050 monitors including my Macbook Pro screen. This is ironic because the single monitor has more pixels). Nevertheless, does Lion experience any UI animation/graphics performance decrease at all like Snow Leopard? Also using full screen apps apparently render secondary screens useless, but is there a chance that this will be dealt with in a future point release?
