Has anyone else noticed that OS X's Expose (and I guess now Mission Control) feature gets choppier/more sluggish with its animation with every successive release? On Snow Leopard, I am using the old Leopard Expose and it works pretty smoothly. It's threshold for slight choppiness/sluggishness is about 30 or so windows. Up until then, the animation is totally buttery smooth. With the Snow Leopard Expose, the animation's threshold for losing complete buttery smoothness is around 7 or 8 windows. After that it becomes a little jittery. Around 10-15 windows is where there is a clear noticeable difference in smoothness between the Leopard animation and Snow Leopard animation (I've set up a script to quickly change between the Dock's to get the best comparisons of smoothness). Now with Mission Control, I feel like the choppiness starts to hit as soon as 4 to 6 windows. I am using a dedicated video card (330m), so that shouldn't be the problem. I've manually modified kexts and plists on both Snow Leopard and Lion to eliminate any power management of the graphics card (the thresholds are even worse with the graphics power management), but I'm just wondering why are the animations getting "worse" with each new release? All animations are buttery smooth in Lion, except for the Mission Control animation. This is not an unbearable choppiness that would indicate something is seriously wrong, but it is a slight yet still significant/noticeable choppiness that did not exist in the previous version of Expose/Mission Control. As someone who is a little too OCD about the smoothness of animations, I am curious what is so intensive about these new Expose/Mission Control animations that causes the choppiness. None of the windows use any flash or anything intensive. Why doesn't it happen when changing spaces or invoking Dashboard in Lion? Is this just the result of Lion being a .0 release so far? But the Expose in Snow Leopard is still choppier than Leopard's Expose, and Snow Leopard is a mature release.
