Nvidia reps sometimes work with game developers to implement PhysX that are best suited to their GPU's for hardware accelerated PhysX. Bohemia Interactive are using nvidia's PhysX SDK in ArmA 3 to run purely on the CPU so as not to alienate amd gpu users. I'm not sure if BI are using PhysX 3 SDK or in what way BI ArmA3 devs will use PhysX for, fluid?, cloth? Ragdoll?.

All this considered, (i was reading about this earlier) what other reasons for a Nvidia over AMD GPGPU?
Agreed,
I was just playing bl2 on my boys amd pc and the option for physx was locked on low and greyed out

Given i own a 3d tv maybe i should think more about 720p3d even though it sucks.

Interesting... What graphics card and drivers?
There must be something causing this. I've had 2 installations of BL2 and had full control over it.
I have a 50" st50 and 720p 3d is the best 3d I have ever seen
Far better than any of my bluerays or cinema
Even tried out tridef 1080p 30fps 3d gaming and although the resolution was better it didn't have all the pop out goodness that came with the nvidia 720p 60fps.

I beg to differ, have you not played Batman Arkham Asylum? There was some great moments in that game where PhysX brought it to life!

Alice Madness returns made good use of it too, although granted there's not many titles that do do it well

I bought one of the refurb 460's OcUK were selling cheap a month or so ago purely so I could use it for PhysX.
Setting up was pretty simple, I used P10-17000's Hybrid PhysX setup: http://www.ngohq.com/graphic-cards/...with-latest-physx-and-geforce-285-solved.html
It works great in Batman Arkham City (replayed through for a third time just so I could see the PhysX effects), and I've restarted Arkham Asylum tonight for the same reason - again, runs great with the 7970 doing the 3 screen display and the 460 doing the effects. After I've done Batman's, I may give Mirrors Edge a go even though I never got into when I originally bought it.
Is it worth doing? In all honesty, probably not. If you can get an Nvidia card cheap and you really enjoy the half dozen games that use it well but have a powerful AMD card, then it's worth it. For the 95% of people this doesn't apply to, I'd say don't bother. In truth, once I've finished Batman and given Mirror's Edge a go, I will be taking the 460 out as it's simply not worth the little extra on the PSU (the card is never stressed just doing PhysX) and the sacrifices - I had to lose my USB3 header to get my motherboard to run the PCI-E slot it's in at x4 rather than x1 (tried both and I got FPS drops at x1 in game).

6790 12.10 catalyst
This is on 960t so would have no chance of doing physx anyway
Maybe the configuration is something to do with it? Maybe they locked te setting down depending on your setup and the only way around it if you have been liked down is via the config ini. But if you have a decent CPU/GPU it's unlocked?
I don't know, but I refuse to believe its random.
