Hehe, well, I did get my answer......LOL!

Hanners at EliteBastards seems to have the first article on PhysX power Pack 2:

Here is the link from nVidia:

Going to find out about Kenneth Bugeja and his demos.

Edit: It seems Kenneth entered the PhysX contest and made an impression -- good for him.

It's certainly nice to have a PhysX ability with a single GPU but by adding a cheaper GPU or older GPU for a discrete PhysX GPU -- one garners some additional frame-rate. This is great for my older 8800 GT that is doing nothing right now and can use it for a discrete PhysX GPU. This should be a great option moving forward as hardware improves.

I suppose with Sli or Tri-SLi -- the raw performance of two or three GPU's doing both should be a pretty powerful solution.

Good read from Hanners.

I'm curious to hear how PhysX works with 3 cards installed. What I am wondering, if possible, is if I could use my two GTX260's in SLI and then add a 3rd video card dedicated to PhysX (possibly grabbing an 8800GTS/GTX crazy cheap).

I don't want to lose the benefit of SLI performance by dedicated one of my two cards for a PhysX board, and I have the capability to add a 3rd card.

1. Is this possible?
2. Is there enough performance potential to justify DOING (nothing the expense) it?
3. Would I see any gains in games that are currently out (Fallout 3, Far Cry 2, Crysis, etc...)?
Yes
Possibly, game dependent and resolution/quality dependent.
No, except for the PhysX levels in UT3, and that free PhysX Game in the last feature pack.

I get a bit angry when HavokFx was working years ago with nVidia and ATI with Shader model 3.0 and finally now we are seeing slowly GPU Physics to the end-user.

An older demo with nVidia and HavokFX:

After rereading Hanners piece, you know, the performance with 1920 x 1200 with x4 AA with PhysX on a GeForce 260 192 product is impressive in UT.

http://www.elitebastards.com/hanners...t3-tornado.png

http://www.elitebastards.com/hanners...t3-heatray.png

Considering this is from a single GPU doing 3d, high resolution, with x4 AA/x16AF and Physics and hitting around the 60 average.

I wish they'd done XP running a 4870 1Gb with a GTX260 216 as physX, to throw some comparisons on how pure GPU physX compares across brands.

Can you do that??? I have a spare 8800GTS 640 now sitting and beginning to gather dust since installing my 4870. If I can put the GTS back in and use it for PhysX, then I get the best of both worlds! PLEASE say this is doable...

A small article about the second power Pack and reminds the readers about Mirrors Edge and Bionic Commando. Going to check out if there is anything new about Bionic Commando as of late -- that title should be getting close as well.

From Japan:

Nice little article that touches on the 3d stereo, second power Pack, and a small interview with Jeff Yen ( Technical Marketing Manager, APAC, NVIDIA) on PhySX over-all?

There is a sceen shot of applications coming but quite can't make it out in the bottom of the page.

Thanks Zogrim!

Here is an article I found by accident with nVidia and HavokFX a few years ago -- has a few PR slides, hehe!

Edit:

What a great read. Get so angry because gamers could of had GPU Physic potential years ago and would be much more mainstream now, one may imagine, instead of just starting now.

Well, I blame Intel mostly, and AMD too, both of which are in the business of CPUs. So to move the workload away from the CPU, isn't exactly in their interests. This is why I see AMD supporting Intel with Havok.

Very political to me. Trying to gauge Sli performance with PhysX and there seems to be some scaling when looking at a 9800GX2 vs 9800GTX -- which are similar cores -- with the 9800GX2 core using a lower clocking on each core.

GX2 has two gpu's rendering, thus higher fps... even with lower physX performance on 1 gpu vs. 9800gtx. 9800gtx sli would likely perform much better than gx2. unless I missed where they restricted it to 1 gpu test.

What I am trying to gauge is how well Sli will scale in PhysX examples. There isn't a lot of investigations on this -- most of the investigations were with a discrete PhysX GPU and a single GPU. Remember reading some Sli views but can't remember where, hehe!

I think in part thats because SLI has only recently allowed physx to be enabled with SLI enabled, too.

Looks nice, thanks for sharing! When listening to the developer in a video interview this title suppose to have the most PhysX effects over-all like frost the on the walls the freeze then unfreeze, etc.

Just glad to see nVidia aggressive to try to bring GPU Physics to the gamer.

Hmm... It certainly is a good start.

Me being the picky bastard that I am though, the water appears to jelly-like and gloppy, I didn't like the fake water-ripples that were obviously shader-generated and not physics-generated when objects were thrown in the pool of water, and the scripted cloth-waving was obviously not natural movement in a few places.

Still, once again, it's a good start. With time and more power, it'll only get better.

Everything is in steps in my mind-set and the part that I liked is when the wind was moving the water across the table around the objects. There all subtle when you take each individual aspect but when there are a lot of subtle aspects -- really takes hold and raises the bar from a good experience to a great experience to me.
