Rain is definitely in, but that was the only weather effect that happened.
There are a heavy amount of bloom effects in town.
Depth of Field is gorgeous on a clear day. I was taken away when I first got out of LL.
Ambient Occlusion rapes my FPS, I had to turn that off or suffer a constant 12-15 FPS + sluggish mouse (Intel Q9550, nVidia 9800GTX+)
Sad to say that the Char Creation completely misleads you and tells you FFXIV is 60 FPS capped now, only to drop back down to 30 FPS cap the moment you enter the game.
SLI is working just as well as it does in the benchmark; that hasn't changed (yet).
No server choices, but if you choose the same name during multiple char creations, the lobby will automatically attempt to create on a server where your name is not already taken (though this is probably a rare scenario).
The current client also definitely allows Language Bar based Japanese typing in at least the English language client.
There was only one guildleve at the first Camp available; I didn't go back to town to check if others were available at the desk.
Weakened State is shorter than it was in Alpha; I'd estimate 3 minutes, but I only died once. I used to be able to walk from the first Camp to Cedarwood in one weaken; I only made it 2/3rds of the way.
Everything else that comes to mind after that are all battle related. If there is anything else, I'll probably edit this post.
