When I am walking, the game will lag momentarily to load the world ahead of me. It does it with 'Old' or 'Infinite' worlds. This never happened with 0.8.1, the chunks would load gradually as I went. Now it seems to load a large amount all at once, causing the game to momentarily freeze. Performance is fine otherwise, framerate, etc.

Also, graphics settings make no difference at all. Tried near/far rendering, fancy on/off, skys on/off, animated water on off, no change.
