Benchmark Results: High Detail, PhysX On High
Now that we know what to expect from PhysX on Normal, let's see the performance penalty associated with the High setting:
The average frame rates haven't moved much, but the minimums have all been pushed below 30 FPS, even for the highest performer, the GeForce GTX 260.
Oddly, despite the added processing demands, the minimum and the average frame rates have not moved on the Radeon cards.
Let's see what happens when we add a dedicated card for PhysX processing.

Great article, really informative. Looking forward to hearing back from the devs regarding CPU usage.
cant wait to try it.
This is a Games for Windows Live product. Or On-line account Evil DRM malware tracking software required.
I really want to play this; but alas I cannot buy it
Wow..I didn't expect GT 220 is a good dedicated Physx card,.. Off searching in eBay LoL
Looks to me like nVidia had this game rigged to better benefit it's cards, note the decrease in CPU involvement as the physX options are cranked up.
That is why Arkham Asylum should be Game of the Year - It is a work of art!
Would a setip with an Nvidia card for PhysX and an ATI card for graphics work? Noob question i know :-P

I don't think it's a daft question - there was a= bit of news or an article a short while back saying that nvidia had set something so that physX couldn't be used if there was a non-nvidia card handling the graphics (or something like that). I was going to raise the same question as to 'can the GT220 be used as a physx card regardless of the main GPU?' as I can't remember much about the other article.
I play this game using 2 8800GTs, one for graphics and one for the physx (on high).
All settings on max and res at 1080p
Benchmark gets about 40fps, played the whole game though with no noticable slowdown.
The physics were locked down because PhysX is an nVidia product (no one supported AGEIA dedicated cards when the original company (Ageia) was making the entry to the market),as some profit based companies would still use havok at that times and not see the huge potential of the PhysX of AGEIA, it's only reasonable that now that Ageia merged with nVidia, they want to make profit by selling their graphic cards.
The second reason, I think, is that the PhysX wouldn't even try to use the CPU for Physics for performance related issues (smooth frame rate in every case scenario rig).
As I recon, AMD is making a move in the Physics with the 5th serie.
Just wait and see... Again
