IMO. Physics cards are no longer needed. The dedicated ones displayed above have been replaced by more powerfull CPU's and GPU's with onboard Physics processing.

And soon enough GPUs will "no longer be needed" either, since they will be replaced by CPU's which can do a better job.

I wonder where that will leave Nvidia.

Slightely incorrect. CPU's and GPU'S are of different architecture. Even a really powerful CPU could never compare to a GPU when it comes to graphical rendering and number crunching..

A CPU would have to have GPU properties on the die for it to do a better job.

We're talking some time from now, mind you, not hard to see how this concept might be applied.

I have been to sooo many 'custom' copmuter stores around where I live...they all swear its the best thing since sliced bread..ROFL! Of course they also sell it for full market+20%....sheeesh. I couldnt believe they are conning peeps into buying these, over SLi, for a real gamer.

As if this makes it worth having->"****, that dead body has been there for the whole game now...amazing..and did you see that little piece of **it, flying at me....I didnt see that one before"

SupCom has marvelous netcode, but their pathfinding is a bit...blah. It seems that they coded the AIs and pathfinding in LUA?

I admire how they can have 3000 units on a map, and no lag on 1.5mbit ADSL, but it certainly does eat multi-core CPUs for breakfast.

Cheaper prices weren't even necessary.

A while ago a hacker took a look at the hardware on those PhysX cards. He determined that the card was structured similarly to the KillerNIC - basically, it can do general purpose processing as well as the standard physics calculations.

But unlike BigFoot, Aegia has not opened up the platform. Nobody can use the processing power for whatever they want. Aegia could've let the cards be a cheaper alternative to multicore CPUs. Instead, they let CPU prices plummet before taking any action, and nVidia has beat them now in physics processing power thanks to CUDA(which DOES let their videocards be used for general purpose processing).

So yeah...they stagnated and never took action.
