I assume Starfox means the transitions like when you open Mission Control, for example.
I'm running it on my 15" 2011 MBP, as well. Mission control is incredibly sluggish for such a new piece of hardware. I'm assuming it is just an issue with DP2 not being optimized for the new models, because otherwise I'm sticking with 10.6.
Other than that, the drivers seem to be just fine - the only issues I've run into are programs (like Evernote) that simply don't run on 10.7, but that has nothing to do with the MBP. Also, I have no idea why when you do a 4-finger swipe up, instead of showing my desktop it simply focuses on the main window I have open.
Also, I wasn't able to get Lion's trim support on my non-Apple SSD, but I haven't played around with that enough.
