When you download the Diablo 3 client there's a "playable" stage and an "optimal" completion. I'm assuming "optimal" includes stuff like higher-quality textures but I could not find any precise details about it. What are the precise differences between the "playable" and "optimal"?
And if my computer is on the low-end of the system requirements anyway, is it even worth it to wait for the "optimal"?

Much like World of Warcraft's launcher, "Playable" means the launcher has downloaded sufficient game code and initial media for you to launch the game and start playing it.
Unlike "available" where you run into "loading walls" where the game client struggles to keep up with downloading media necessary for you to play, "playable" means it has downloaded enough data for you to play without hitting any "loading walls".
The "Playable" includes high resolution textures and other low priority flair:
Therefore, "optimal" means it has completed downloading all available content and will not impact your play experience with background downloads.
