Hi I've read the crunching on GPU/SSE etc threads, but was wondering if this would make things easier to code? I also saw Ethan's post about contacting Ageia (did they reply?) |

No reply after two emails. I guess they're too busy trying to sell cards to accelerate games that don't exist yet :) I did hear that the PPU might suffer the same problem of a GPU, they don't always return the correct result. GPU's give up accuracy for speed, good for graphics since you don't see the random pixel error, but bad for science. The PPU folks probably did the same thing since who is going to notice if a flying piece of shrapnel is off by a degree? |

I guess they're too busy trying to sell cards to accelerate games that don't exist yet :) Actually I would have though a missing pixel maybe wuite bad for CAD (GPU) users or if the Physics (PPU) is wrong then it could have a nock on effect, it's not just shrapnel but animated bodies, trajectories, planes flying. They still need to be accurate. Team mauisun.org |

They still need to be accurate. Those cards were designed for accelerating physics in games. Keep your hands off that cards. They are not working yet. Only a few games support them at all. Of course, the graphics are much nicer and more realistic, but the framerate drops to a degree, I would consider unplayable (< 10 fps). |
