When I upgraded from Leopard 10.5.4 to 10.5.5, the RAM Preview render time DOUBLED for the 900 frame "Blocks-Detail" HD Template in Motion 3 on the GeForce 8800 GT. I checked and rechecked and then reported it on my site. (I usually contact the "usual suspects" before posting bad news but did not have access to Apple or nVidia engineering.)
I'm happy to report that someone noticed and the "bug" is fixed in 10.5.6. The render speed of that template has been cut in half -- in other words, is back to "normal."
