OS X: Any player feedback yet for Borderlands 2 (Mac)?

[LagunaSol]

I'm still on a 2009 iMac (2.93 ghz, 8G RAM, Radeon 4850 512MB) hoping it will run well on this machine until the new 27" iMacs are available.

Any feedback out there?

Playing on my MBPr.

1440x900
details on high
things light shadows, lighting, ambient, foliage etc on low

looks and runs better than it does in bootcamp

in bootcamp I can't do 1440x900 and the game doesn't look good unless I do at least 1680x1050

overall, very pleased

EDIT:

reset the nvram and smc and I can play nearly maxed (except shadows and other resource hogs) without terrible slowdowns. I can't see my fps but it's pretty smooth. The UI (items menu) is slow as all hell, though.

No clue how a GT650m compares to a 4850, though.. you should at the very least be able to play it.
