I'm liking it a lot too. Frame Rates are very smooth on my setup (3.4GHz Pentium4, GeForce 6800GT, 1GB DDRAM, 250G SATA Boot Drive). Tried it at my local hobby shop and the 3D physics were a little off - required a click or two to restore the "default settings" at the launcher startup and changing the "physics quality" settings to "high" before it behaved more realistically. I think it may require a few bug fixes but looks pretty good so far - I'll have to continue testing through the weekend and load the other volumes on.
