I have already stumbled across two games (I mean… um… work related Flash stuff, yes boss, I’m working) which get “choppy” when you hold down the key to move (though it should apply to all keys)
You know when you are typing in word, if you hold down one key, first you get one letter printed, and a second later it writes that letter really fast multiple times until you release? I believe that is what is happening that makes those games choppy. This is likely because the “KEY_DOWN” event gets dispatched very many times for the same reasons.
Now, either both those games were crappy enough so they forgot to test for this issue, or it’s a Linux specific issue. I need you (yes you) to double check (stating your operating system and browser) if you get the same results.
Here is a sample SWF (I didn’t make it):

**If you hold down the key to go left, (or right, doesn’t matter) first you go left smoothly, and then after a second it starts “chopping” and resetting the movieclip’s frame to the first walk frame. **
