New drivers have been released for NVIDIA PhysX. The drivers include a collection of demos made using DB Pro and Dark Physics. For more details see http://developer.nvidia.com/object/physx_downloads.html#System

Mike,
I've been out doing other kind of software for some months, and am curious about this post. Seems I missed something.
Was the original Physx acquired by Nvidia?
Is it recent or always was so? And how about DarkPhysics?

Control Panel-> Nvidia PhysX-> Demo tab

Yes, Nvidia acquired Ageia a couple of months ago.

Mike, regarding the soft bodies demo, are the Nvidia logos not intended to collide with each other, or I see a bug?

Programmers combine theory and practice: Nothing works and they don't know why.

Ohhh. I thought maybe they would supply the code so you knew how to do all of that

DarkPhyx with DarkGDK still fetches and loads up the libraries PhysXCooking.dll and PhysXCore.dll from v2.73

any chance to update the system to use the new nvidia v2.81 dlls ?

I like that the size of the drivers has dropped by about 30mb.

Does anyone know anything further about when nvidia drivers will make the 8800ultra gpu capable of doing the PhysX?

June 18th - NVIDIA day. Two GPUs, aimed to be the true successor to the last enormously successful cards, the 8800 GTX and Ultra. And they are hence named - GeForce GTX 280 (D10U-30) and GeForce GTX 260 (D10U-20).

The GTX series is NVIDIA's first attempt at incorporating the PhysX stream engine into the D10U shader engine as well - Cuda is coming.

Odd, a few days after Mike opened the thread my computer took it upon itself to download and install the update. It's an HP 9150f that came with an NVIDIA card pre-installed. Nice feature, I guess. It apparently keeps track of updates to whatever I came with.

Well, the driver is useless if you don't have a physx card, isn't it?
I don't understand why DarkPhysics needs the PhysX thing, it's annoying.

The drivers are not useless without a Physx card. You can now run fluids in software (you do need a decent graphics card)

@ Mike,

One thing I noticed on the NVidia website was that under PhysX Tool Developers and Partners page, The Game Creators isn't listed. I figured with as many contests you have run wtih them, and the fact that you have tools that support PhysX you'd be listed. It's a wasted advertising chance in my opinion. Anywho, keep up the good work.

@Gunslinger: the Physx commands reside in the drivers dlls, so how can you use Physx without the drivers, card or no card?

Soon we will see Physx for CUDA, so anyone with new Nvidia GPUs will have hardware Physx. By the end of this year there will be a vast userbase, so start developing your Physx games now!

My wish is that Nvidia make a better setup for the drivers. Right now the system has to set registry entries to work and this is a big no no under Vista. Instead of making 5 different dlls, they should just put everything in 1 dll which you put in your game folder, without any need of installing drivers etc...

@ bjadamns,

Thanks for the heads-up - but will my 8800 Ultra be able to do the Physx hardware ?

your 8800 will support physx in hardware through CUDA, only WHEN Nvidia releases a new version of the physx libs to use Cuda instead of the physx hardware that is available now.

some 8600 cards will have support too. plus obviously the new 9xxx range.

that will happen later on this year.
