techreport.com — Nvidia completed its acquisition of Ageia yesterday, and it has revealed that it will soon introduce PhysX physics processing support into all of its GeForce 8-series graphics cards through a simple software download. PhysX support will allow the cards to accelerate physics effects in games.

Those demo maps still show that the phsx does make a sizable difference (despite the fact that it's still not up to par... for now.)

Some games. Not every.If you can challenge 8800 with Liero, I'll give you a good clap.

Quite frankly I have yet to see any good use for PhysX...thier engine isn't even that great, which is another reason why developers don't bother with it. It's not so much "physics" as it is particle effects.

this is really kool they can rape customers by charging for this somehow but they're not

Or you didn't and you just want to disagree anyway cause you wish you were right.

That' "stream processors", which is really a misnomer IMHO. An 8800GTX has 16 (fairly) discrete processing units, each capable of performing an 8-way SIMD instruction. Nvidia multiplies those two numbers together, mostly for marketing purposes. Essentially, you can process 16 different instructions, on 128 pieces of data simultaneously. Still very impressive, especially for highly paralellizable problems, but not quite 128 processors.

Agreed, the 100+ stream processors in some of the higher end 8k cards would eat through physics computations, but for the sake of argument, why is my machine at 25% CPU utilization when running crysis?

overclocking in the 8800 series is nice, Ive clocked my 8800 GTS 640 up to basically slightly above standard GTX specs with a negligible heat increase which I was kind of surprised but very nice performance and I'm intrigued to see how this PhysX thing pans out for it.

dugg up for truth, overall from what Ive seen comparing Crysis on DX9 with DX10 though there isn't enough of a difference for me to care, there wasn't any real notable improvement if any at all and before I get dugg down for this comment I would like to say that DX10 and vista were in my opinion more or less just another winME scheme to feed the wolves so to speak till they come out with their next OS which as far as Ive heard is to feature DX10 and the option of DX11 which is supposed to surpass it and hopefully it will deliver.again just my opinion so meh.
