FYI - Batman demo to download with PhysX...

[RPGWiZaRD]

I just gave it a quick try, for me at the first fight with physx settings off I had 90~100 fps at the first fight with physx off and on normal around 50~60 FPS and same at high with no visuable difference.

Oh and those intro vids are annoying (nvidia logo etc), remove them by clearing this section in DefaultEngine.ini:

[FullScreenMovie]
+StartupMovies=esrb
+StartupMovies=baa_logo_run_v5_h264
+StartupMovies=UTlogo
+StartupMovies=nvidia
+StartupMovies=Legal
+StartupMovies=Install

Always brings me a smile when I find this comment in all the unreal3 engine games engine ini:

; mostly copied from 2k4
[Engine.DemoRecDriver]

ie, copied from Unreal Tournament 2004. So much junk code left there that's not used or removed.

EDIT: Now here's a funny and weird one, applying 4x AA with physx off I get a FPS boost over no AA, FPS climbed from 90~100 FPS to 98~135 FPS! lol And yes AA is working nicely. Must be the first game I've tested that both looked better and ran faster after applying AA.

Any1 else experiencing the same?
