    I have seached this forum for performance numbers but with no luck.

    Can anyone please help me with:

    1. Performance numbers; TL poly counts, Fillrate etc.

    2. Any special hardware ligthning/shading capabilities

    If you have found other threads were this is being discussed, please drop me a link :)

    how many triangles is very different depending on what 3d engine you use(if you use one), the only one I know the specs of is sio2(http://www.sio2interactive.com/HOME/HOME.html). With the current version you can have 15k triangles drawn at 40fps+ on ipod touch 2G, in the next version it's 30k at 30fps+(still on ipod touch 2G), these numbers are with texture and maybe light, but without physics.

    How many triangles you can render per FOV depends on lots of things like:
    • texture/multi texture
    • physics
    • light
    • animation
    • how much time everything except the drawing uses(AI etc.)

    For your second question: you can use OpenGL lights

    It's seem to be more powerfull than I initially had predicted - I was thinking DS times 1,5 :)

    Well theoretically its almost at the Dreamcast level, it based on the same PowerVR chipset that was used in the SEGA Dreamcast, though running on a lower resolution screen.

    But since its running with the iPhoneOS and that Apple made some restriction, we are probably loosing a bit performance. But the more people develop for it, the more they will find way to get their code optimized and I am sure Apple will do the same with the iPhoneOS also.

    Just take a look at the recent Need for Speed video from EA posted on the site here. It surely shows that it can be quite powerful.
