The Physics Processing Unit or PPU for short is just around the corner so to speak. This will be the next huge jump in gaming performance, hopefully will give us more FPS on older systems and at the same time give a quantum leap in flight simulation and ballistics. Here is a link to Ageia the company claiming to be first to have a chip dedicated to physics computations www.ageia.com (http://www.ageia.com)
Please Oleg will you be able to impliment the NovodeX Physics SDK or similar into FB-AEP-PF?

The Physics processor cards are a flight sim makers dream I would think. A great tool to pull the flight model (read physics) off the CPU. No doubt if Ageia makes a reasonable driver / interface Oleg will use it.

A separate/dedicated physics processor? Hey, that's a GREAT idea...

that is not something easy.. Ageia expose this features by their own physics engine. Tryint to use this in FB means throwing Olegs Physics engine by the window. And Ageia engine is not even close to Olegs one when handling physics needed for flight (I worked a lot with their SDK and is not that impressive)


Also I don`t beleive much in this product they proposed (the idea is good.. but not the product). Using simple PCI-E 1X it would have latency and bandwidth inadequate for most physics stuff I can imagine that could make use of good harware acceleration. I am still with my money on a future cell processor add on card to be used on PCI-E 4X

Oh man OldMan, I'm hoping cells catch on. The PC should have died 10 years ago.

Well, we will see very soon how well it performs, E3 is 3 weeks away.

Dont worry about PCI...

ASUS is includig the PhisX technology in their motherboards from 4Q of this year.

This Technology is here to stay... for good and benefit of all simmers. Is up to the developers to adapt or... else.

Once the simmers have tried a FULL physics model, sure they won't come back to PARTIAL models easily. The human being adapts to the good things really really fast.

On the other hand, do you remember math co-processors on old 386? I do.

And look where 386 mathcos are now.

Hey, I got my dad to buy me a mathcos in the early 90´s, cause my 386sx didn´t have one. I think its buried under 10 years of waste in my hometowns waste disposal site. Did it make run the SWOTL any better? no, but it did give me faster calculated images on my fractint.. http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

Unreasonable for FB+AEP+PF...but perfectly possible in the future.

Maybe with the PhisX chip, we could get realistic dispersion? http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

The fact, that this chip is called "Physics Processor Unit", doesn't mean it is suitable for ANY physics calculations. From reading their site, it looks, like this is just a specialized FP matrix calculation unit.
Ageia created their own high-level API fro this unit, mainly oriented at the animation bones transformation calculations. This may help to create high quality visual animation effects, like realistic water waves, waving grass and trees, etc. with low load on the CPU. But this hardly can help for flight dynamics calculations so far.

uhh it does mention Fluid dynamics as being a capability. I don't know what or if there are limitations and how it can be used in flight sims.

At teh LOMAC webboard somebody asked the Devs for grass waving in the wind.

I posted they can get Lawn Mower Sim.

well, the side effect if used is that the cpu is used on teh gfx less, so u have more free cpu time todo FM's. in theory anyways http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

could also help with crashes, bullets bouncing of things, that sort of thing http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

alsho our mossie would fall apart and splinter like a modern saftey devices like crumple zones, whereas the metal structures would be more likely to transmit the force of teh impact http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif
