Decided to do a recorded run through of the two in game Metro 2033 benchmarks.  The Redux subway tunnel battle and the Last Light marketplace walk through.  Both were done with max settings.  And by max, we’re talking actual max.  As bad as Metro can get:

First up, Redux:

TL;DR – 50fps average.  Looks like we lost about 8% from Advanced PhysX.  How about Last Light?

Slightly better at 54fps.  Same as we saw in the previous entry with PhysX off.  Unfortunately we also see the same drop of about 8%.  Of course Advanced PhysX in Metro has always been known to be broken on some level and doesn’t actually do anything in the game, so this is largely synthetic, but interesting nonetheless.
