Official PhysX Thread

Here is a small interview with Manju Hegde and Curtis Davis from PCGH:

Touches on PhysX APEX and scalability over-all and other subjects.

Manju Hegde was the former CEO of Ageia and Curtis Davis with the former President/COO of Ageia and now VP's with nVidia.

Here is a small article with Manju Hegde and Curtis Davis in a round table discussion so-to-speak:

Nvidia (or anyone for that matter) plugging game physics is nothing new, but what really stood out at this session was how adamant the chaps were that PhysX was genuinely Über and not just a marketing ploy. Taking lead in the Q and A session, Manju Hedge was a force to be reckoned with; his confidence in PhysX almost enough to wash away the obvious scepticism shown by the journos at the small table. Furthermore, it would seem that these two top PhysX guys have transferred their optimism to the game developers. “We have an incredible amount of games on the way that will support PhysX’ stated Manju, ‘the majority of top developers are very keen to work with us’.

That's all well and good, but nVidia needs to bring rigid body acceleration to the GPU as well as cloth and fluids; destructible environments and interactive play will be greatly improved by taking that load away from the CPU and placing it on a dedicated processing environment.
 
I don't disagree and rigid bodies are important.

The CEO touched on Physx in the conference call and basically offered about more titles will be named in the near term -- which is good.

What I would like to learn more about is the scalable aspect of PhysX and, of course, Physx examples over-all. Talk is great; potential is great but examples to utilize PhySX is needed to showcase this talk and potential, imho!
 
Faith’s world in Mirror’s Edge is visceral, immediate, and very dangerous; it is imperative that the gameplay reflect this level of urgency,” said Owen O’Brien, Senior Producer at DICE. “NVIDIA PhysX technology affords us the ability to bring a totally new level of immersion to the game, and by doing so, gamers can truly become part of the world.”

Nice to see some news and another nice title offering PhysX.

With the NVIDIA PhysX physics engine, the world of Mirror’s Edge comes to life with real affects of wind, weapons impact, and in-game movements. Every-day objects within the game become part of the overall experience. Cloth, flags, and banners can now impact weapons and players; ground fog interacts with the player’s footsteps; explosions fill the air with smoke and debris; and weapon impacts are enhanced with interactive particles.

LOL! Just realized Zogrim offered the same link as me...........how the hell did I miss that, hehe!:) Thanks Zogrim! Enjoy that PhysX site in your signature!:)
 
Well, I've posted it some time ago, but the post just wasn't shown.. somehow :rolleyes:

Now, I hope thats Mirror's Edge video was the first swallow, an we will see PhysX revealed in all that 50 games Roy Taylor was talking at Nvision)
 
Being your first post there is some time before the post is allowed or something to that effect -- that explains it!

Hopefully this title starts to get the ball rolling on those 50 titles -- enjoyed the video.
 
PhysX future starts with Mirror's edge


The game should provide you with a dramatic physics experience and some new features, including glass which will be able to hurt your opponents after you shatter it. This was described to us as the glass scene in Die Hard 1, and if you've seen it, you would know what we are talking about.

Apart of shooting glass we've seen some screenshots with realistic steam and cloth, all powered by PhysX,

Nice to see a nice step towards GPU PhysX.

Let's Talk about PhysX Baby

Mirror's Edge: The First Title to Impress us with GPU PhysX?

to under line the differences between the PhysX and non-PhysX version, here's what to look for: glass fragments are a particle system without PhysX and persistent objects with (meaning they stick around and can be interacted with). Glass fragments are also smaller and more abundant with PhysX. Cloth is non-interactive and can't be ripped torn or shot through without PhysX (it will either not there at all or it won't respond to interaction). Some of the things not shown really clearly are that smoke responds to and interacts with characters and leaves and trash will blow around to help portray wind and in response to helicopters.

I've been digging through the links and info in this thread, but not sure yet if this was answered...


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...)?

SLI and PhysX both work at the same time (last I heard anyway, I know both are enabled on mine), so why not do it that way.

I doubt the performance hit would be that big especially with 2 cards doing it.
