Tweaking Batman for best performance

This is my settings:

ATI Radeon HD 5880

4 gb of RAM

Intel Core2Extreme CPU X9650 3.00 GHZ

Win 7 64 bit

---

Should I install the latest Physx Driver? even I don't use the physx feature at all? will just having it installed improves FPS in any way?

What's working best? FSAA, MSAA?

Please regard other settings as well.

I can't keep my game running on steady 60 FPS, on the initial sense with the penguin, my fps is 30-40..

Please help me adjust my options for a good-looking and smooth Batman AC.

[QUOTE="thetrellan"]I don't know where that quote is from, but the words "ransom" and "shepherd" are misspelled. Is that intentional?[/QUOTE]

@thetrellan

Lol, well actually I didn't know I misspelled shepherd, thanks for telling me this.

As for Ransome, some time ago I found out I mispelled that too, knowing this, I liked how the name looks like and so it sticked that way.

As for the quote, this are both taken from a fantastic game called Hostile Waters.

They are both the words of two great character: Ransom and Medson. As for Medson (not sure I spell it right) he likes to quote religious saying from the bible - "The lord is my shepherd" is translation from the Hebrew Jewish pome book "Tehilim" inside the bible, that was written by King David supposdly. As a Jewish believer I like that line alot, both in Hebrew and English.
