Just some things I've noticed:
1. My yalm seems to bob gently when flying - quite nice but sure it was very static before
2. Shadows are not quite missing but are much fainter. Reflections seem much more vibrant too - for example on the inside of the T3 pads. I guess some work has been done improving the lighting model. very nice.
3. There is a new destination window when you grid to the 'org city' exit - I'm guessing this will have many more options soon - maybe so people can grid direct to other org tower sites in LE?
4. The animation when I run looks more natural but overall the framerate isn't as smooth - like it jumps every few frames. I guess this is linked to the change to make other people 'slide less when moving with the mouse'
