Steps to Reproduce:
1. Go into /gamemode 3 and press F3 to see the FPS.
2. Increase the flight speed to maximum. (it is not as noticeable at lower speeds).
3. Fly below the bedrock level for a few seconds.
Observed Result:
The game will stutter just before hitting bedrock level, and below bedrock, there's a noticeable FPS drop.
Expected Result:
The game should still run smoothly.

Even so, the game shouldn't drop in fps when looking up at a flat surface, which is about a third of the number of faces to render as when you are looking at normal terrain.
It's like a Golden Rule of Programming - You give the user a red button that says, "Don't press", and they'll press it. A player could be a spectator in some custom void world and decide to fly under a large structure (not knowing they're at Y1), or a map maker wants to look at they're build from below for some reason.
I think this is because you are forcing minecraft to generate a lot of chunks in short amount of time.
Is this still an issue in the current Minecraft Snapshot 15w47c or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
I don't notice any issues now (if anything, it seems to be increased FPS as it's not rendering blocks - save for a few chunks where the bedrock texture doesn't render, but the rest of the chunk does). I thought it was fixed awhile ago.
There is no reason to be beneath Bedrock.
