Where are the save files located for the steam version?
Just completed the riddler stuff, so that is me pretty much done with the campaign side of things, not got every riddle trophy etc. though.
Will now move onto the challenge stuff.
And, seriously the difference between DX 11 and DX 10/9 is nothing really, have to be up close and really look for the differences, in fact I would say that having physx enabled is better than the DX 11 stuff (you actually notice the physx things without having to really look for the differences), the game looks stunning on DX 10/9 and IMO for this game it is something, which really doesn't matter that much (graphics).
Also I love the little snow flakes when they land on you! Looks pretty damn realistic/good, could maybe do with a bit more landing on the you though!
