FPS? What about quality per frame? Or crap times frames?

I just wrote some code for a responsive drawer menu. I've heard a lot of people worry about performance crapping up the UI in apps, and I figure that my preferred solution is just to reduce the total time per animation. If you try to flip the whole screen over 1000ms, artifacts are clearly everywhere, because you're stressing out the video buffering mechanisms. But if you do the same in 100ms, it's a lot harder to notice them, even if the crap-per-ms is the same. The other thing I'm thinking about doing is actually forcing a low frame rate. Lots of hand-drawn animation came out of the eighties at no more than 6fps... the idea is to keep the user's thoughts elsewhere, if you can. heh
