DALLAS — Carve a wrong turn in the deep powder of the video game "Stoked Rider: Big Mountain Snowboarding" and you'd better brace for an avalanche of swirling white snow engulfing everything as it crashes down the mountainside.

Such games used to be a simple matter of steering downhill and performing tricks as a wintry, 3D world of virtual pine trees and moguls inconsequentially whirred by.

Those games looked realistic, but the objects in them did not behave realistically.

Because of the computing muscle needed to calculate all those snowflakes and their interactions, avalanches were pretty much out of the question.

"Stoked Rider," though merely a demonstration, is one of the first examples of how video games can benefit from a new breed of computer chips dedicated to calculating the physics of a game's virtual world.

Leading the effort is Mountain View, Calif.-based Ageia Technologies Inc. The company is the first to offer a specialized computer chip — called "PhysX" — designed to give video games a better sense of reality, as dictated by Newtonian physics.

"I've always been bugged, that with all the high-power technology, that the games aren't more realistic," said Manju Hedge, Ageia's co-founder, chairman and CEO. "Computers are very underpowered for a lot of things."

That's certainly true in video games, which tend to be one of the most demanding tasks for computers.

The idea behind PhysX is to take the strain of physics calculations away from the central microprocessor, freeing up all sorts of possibilities in video games.

The processor comes on a card that installs into a free slot inside a desktop computer running Windows. It's able to process hundreds of thousands of moving objects at the same time, its creators claim.

So what does this mean?

Imagine you're in an industrial warehouse packed with wood boxes, piles of lumber and oil drums. And you just so happen to have a grenade launcher at the ready.

In the real world, blasting these objects would have obvious, chaotic results: the boxes would splinter and burn, smoking logs might roll across the floor, and the spilled oil would roil and slosh around the ensuing mess.

Take this situation into the traditional video-game realm, and everything becomes static. The virtual boxes may burn and move around, but they would never break into splinters like they would in the real world. Same goes for the logs and the oil.

The reason? Limited computing resources.

Between the computer's main processor figuring out the artificial intelligence of the game and the video card displaying the graphics, there isn't enough leftover power to bother with the enormous amount of data crunching needed for more realism.

"It would always come at such a high performance cost, there was always a trade-off," said Jeremy Stieglitz, president of Artificial Studios in Gainesville, Fla., which is developing a game that takes advantage of the PhysX chip. "What PhysX does is really eliminate that trade-off."

The advent of such specialized chips mirrors the rise of dedicated 3D video cards in the mid-1990s.

Before PCs had 3D abilities, video games relied on software tricks to fool players into seeing a game with depth and perspective when it was actually two dimensional.

There wasn't enough processing power for real 3D.

That all changed when companies like the now-defunct 3dfx Interactive debuted specialized chips to quickly process 3D graphics.

When coupled with special software, popular PC games at the time such as the first-person shooter "Quake" were transformed into fluid, 3D worlds.

The industry never looked back. Today, 3D graphic chips are standard issue on PCs, laptops, even cell phones.

It remains unclear how many will buy into a product like PhysX.

PhysX does not work in laptops, nor is it compatible with game consoles like Microsoft Corp.'s (MSFT) Xbox 360 and Sony Corp.'s (SNE) upcoming PlayStation 3, which pack speedy multicore processors but lack physics acceleration at the hardware level.

Ageia's chips, which became available last month, come preinstalled on certain pricey, ultra-powerful PCs from Dell Inc. (DELL), its wholly owned subsidiary Alienware Inc., and Falcon Northwest. But these systems cater to a select group of hardcore gamers willing to spend $5,000 or more for a PC.

Two electronics manufacturers also sell standalone add-on cards for about $300.

Only the highest-end PCs need apply. PhysX requires a system with a speedy processor and graphics card — after all, all those extra bits of flying metal and glass still have to be drawn on the screen by the graphics card.

In fact, lower end systems may see a performance hit with PhysX.

Jupiter Research Vice President Michael Gartenberg said hardcore gamers who are already spending such large sums will be the first to snap up PhysX. Convincing other PC users could pose a challenge, however.

"Video games look pretty darn good as it is right now," he said.

So far, the chip is limited to mostly game demonstrations, with only two full-blown games available: the PC version of "Tom Clancy's Ghost Recon Advanced Warfighter" and "City of Villains."

An early version of the action shooter "CellFactor" is available to download as a demonstration but the final game isn't scheduled to be released commercially until sometime next year.

Hedge expects there to be 20 games using the chip by the end of the year.

At Cryptic Studios in Los Gatos, Calif., producer Serdar Copur said it took about four months to add the Ageia physics support to the multiplayer online role-playing game "City of Villains."

The result is a new level of villainy for players: newspaper racks can not only be tossed around, but when they smash into something, the contents fall out and swirl around. The wake left behind as you fly around at high speed actually pulls around bits of debris just like it would for real, assuming you could fly.

"Physics provides the ability for players to feel like they're seeing something new, they're doing something different," Copur said. "I can certainly see there being a huge market for this."

Great job copying that!

but honestly now... i's old news... yeah, as in, really, really old news

[NeMeSiS 11]

Foxnews?

Anyways, why didnt you paste this into one of the other 5 topics about this?

[Nemesis6 0]

Foxnews?

Fox News kicks ass. Look at how they grill this Christian fundamentalist nutjob - http://break.com/index/crazyfox20.html

Foxnews?  

Fox News kicks ass. Look at how they grill this Christian fundamentalist nutjob - http://break.com/index/crazyfox20.html

Why the hell is that on the news anyway? (its fun though)

Yes, I do agree Fox News sucks.  But while trying to get an image of the world, of which brought me to the pathetic Fox News station, I was set off track (or perhaps for them it is really on track) and came across this article, and since I play OFP, thought to myself, perhaps this would be good for the game, but hey I didn't know it was old news. Hahah but then that just makes sense for Fox News hahaha

later

LMAO i wana watch fox more LOL

"You are the devil, Miss If you belive in the bible, you are going to go to Hell" LMFAO!!!   i might go burn her church for the hell of things lol i feel a long road trip coming..

lol I saw that Fox "news" item on the ABC Television's The Chaser’s War on Everything.

Then they got one of their cast (a guy) to crack on to one of the strange church’s protesters (also a guy). Funny stuff.

Shame it isn't one of segments available for viewing on their webby.

-------------------------------------------------

PhysX chip is proprietary, which means the developers have to use their physics engine, which means developers would have to switch physics engines by purchasing Ageia development sdks and possibly tools to include PhysX support in their games.

There are more promising engines then Ageia’s…

If anyone could write code that could run on the chip that would make it more attractive, but noooo you have to use Ageia’s stuff.

AGEIA PhysX Software Development Kit is free for non-commercial and commercial development starting from version 2.6.

[Spoock 3]

Physic will be probably calculating with second core in procesor, which is standart for games yet

[Mr_Tea 0]

We didn`t need an Physics Chip.

Multi-core processors are standard, and the upcoming DX10 video cards will be able to process physic effects.

What for buy an extra card for that?

[baddo 0]

Do you want your video card to do physics calculations or perhaps do graphics processing? It might be the way to go if there must be additional physics processor, but it shouldn't take anything away from graphics detail and performance imho. If you put physics calculations into a graphics card then it's not only the processing power, it's also about how much data will need to be transferred. I'd rather use a graphics card only for graphics, to the full extent.

Multi-core processors, yes yes. Very good thing but difficult to develop programs utilizing them properly. Easier to use AGEIA PhysX multithreaded physics engine, and if you want, go even further and install their accelerator card.

AGEIA will have a hard time getting developers to utilize their PhysX accelerator card (that's why the SDK is now free for everyone). One important thing to notice is that the AGEIA PhysX Software Development Kit does not mean you need to use the accelerator card. So developers are free to ignore the accelerator card and just use the physics engine like before. Or they can require the card but that wouldn't be wise.

Physics calculations in games are not very advanced. There is so much more that can be done in games. There is much room for improvement, and AGEIA is trying to help developers do that with their SDK and card. I wouldn't write them off just yet.

I wouldn't write them off just yet.

I would. I dont fancy a situation in the future where Physics card support is mandatory and we all have to go out and buy a €200-300 Physics card along with a similarily expensive Graphics card to run games. There are people out there who are saying that multicore CPUs spell the death for graphics cards. While I wouldnt be quick to believe that thats going to happen any time soon, I see no reason why game designers cant use a CPU core dedicated for physics. We have quad core, and will soon have octo core CPUs, and most games are still single core only. Lot of potential performance going to waste. So, in the interest of the average man on a tight budget, I wish that Physics cards would die off like other similar obscure technologies.
