Is FSX going to use the new cards made by Ageria:
http://www.ageia.com/index.html

the fluid modeling could make for some awsome storm effects as sheets of water fall off the wings and as the phyisics are not just visual effects the water ect. could affect the planes handeling with it's weight on controll surfaces ect.

also things like wind could be modeled alot better and colisions could be much more realistic (think realisticly crumpled gear).

It takes a little more than a GFX card to model physics of a real world.  Research companies use over 4000 supercomputer processors just to model a few seconds of water, and that takes 3 weeks of processing.

I expect the approach taken in Half life 2 would be more appropriate.  Where things like that are scripted rather than modelled.

However it can certainly help the performance of games and allow a better more realistic looking world.

I heard a while back about GFX cards having a seperate processor on them designed specifically for enhanced (performance/quality) physics engines.  What happened to that idea?  ???

this card is capable of real phyisics not just fancy effects.  Forces such as gravity are modeled corectly which is why it's so awsome.  ;D

Yes, but FS wouln't use that. Those are $1,000+ cards. Most people want to spend $1K on a computer, not on a GPU alone.

PPU!
no gpu this is a dedicated proccesor for phyisics and they will cost about $250 not $100 and fit pci and PCI-E slots.  They are to be available Q2 06 and are to be manufacrued by BFG and ASUS.

Very interessting,....guess something to look into.

Screw the water, this could mean huge improvements in the flight moder. Just think proll stall, spin, off-axis performance.

Or real like aircraft spins, stalls and departures, woow that would be super fly. Really interessting topic there...

Well have any of you looked into the engine behind DX10? Alot of the features described here are going to be avalible. Plus they have been telling us that FSX is going to be more real than ever, and not just the GFX. So I believe that flight models are going to be way improoved, and we may be the nearest we ever have been to the utmost realism.

Guys,you are missing one important point-this thing has nothing common with graphic card...Its completely different device.Graphic card NEVER caclulates physics and dynamics,its CPU's job only!

So Physics card its addition to CPU,not to GPU,so why should it be combined with GPU?Did anybody ever combine LAN card with HDD?

These physic engines are build to simulate hard/softbody dynamics,fracture systems, ragdolls, fluids and stuff like that.
I don

@sterk.. with pixel/vertex shader you also can programm physical behaviour directly into the GFX Card

physical behaviour of what?

The word "shader" already means that we are talking about graphical stuff,wich isnt handled by this device.

"Shader" is the way graphic card draws object on our screen.Physical interaction of this object with

I know.. usually the word "shader" just defines the behaviour of a surface relative to a light source. But the definition
Pixel/Vertex Shader goes much further.. For example they use pixelshader to simulate 2d warp effects on a screen or bending Surfaces.. etc.
Im general you probabely could code anything with vertex/pixel shader. Also physical behaviour.
Of course the GPU is not optimzed for such operations
like a PPU would be.. but it works !!
check this PDF...
this is the description of a demo that uses the Shader Model 3
to simulate clothes (softbody dynamics)

Here a short quote from the PDF

""
What Is This? The sample demonstrates how to use Shader Model 3.0 to simulate and render cloth on the GPU. The cloth vertex positions are computed through several pixel shaders and saved into a texture. A vertex shader then reads these positions using Vertex Texture Fetch (VTF) to render the cloth.
