Mac OS X "Has Mountain Lion been feeling faster for you compared to Lion on the same machine? It's probably not just you: Mountain Lion appears to include improved graphics drivers and low-level graphics subsystem improvements. According to our testing, these improvements result in an approximate performance increase of up to 10 percent. Those improvements can make your current hardware feel faster despite the fact that your CPU can't magically crunch numbers any faster. The changes also lay the foundation for Apple to update OS X's OpenGL support in a more timely manner, which could potentially lead to better graphics performance in the future."

iOS or MacOS X developer? WWDC videos are there to detail such changes ;) .

I had a look at the videos and they really don't go into much details other than "this is what is new and this how you use it" but nothing mentioned on how Apple actually has improved the underlying performance such as "we're now using Core Animation in more areas, we've migrated the Core technologies from OpenGL 2.1 to OpenGL 3.2" etc. This is the one thing I love about Microsoft - when they changed GDI in Windows 7 they not only said, "this is what we've done" but actually explained how they went about it, the design limitations before and how they were addressed. For me I think that if Apple spent the sort of time Microsoft does they would earn a decent amount of geek credibility as a company that makes great products but there are some real technical underpinnings.
