    Yeah, that would make the 9800 XT, ok, let's say 5X faster then the NV40 then. Which would make the NV40 what, 2X slower then the NV30 ?

    It gets better and better.

    That's an explaination, maybe you are right.

    But if I was the PR manager from nVIDIA, I would not let Epic demo the UE3 on NV40 in the first place if there was such big differences...

    I would not pay to demo my baby at 5 FPS, let alone in the same room with a card runs 5X faster. Man, I just think it's ridiculous. :shock:

    Well with dave cryptic post, may we think that R420 will at least not need a very exotic cooling solution to work fine ?

    Pretty cool how you can get 5X out of one card runs choppy and the other runs smooth. You're amazing dude!!!

    You guesstimated one was running at 5-10fps, the other at 30fps at a much higher resolution. So yeah.

    @ SpellSinger

    Excuse me, nothing against you, but I believe your information no word. Either the Epic guy has said something wrong or you have understood something wrong.

    16x1 vs 12x1 by 5x faster ? ...

    All details without Shaders 3.0 ? .... :?:

    I'm thinking maybe Epic was using PS3.0 for NV40 and PS2.0(2.b?) for R420, and nVIDIA just had a bad implementation for dynamic branching. :lol:
    We all know there're many methods to do dynamic branching and the performances can vary a lot.

    Could be. Both ATI and NV will have lots of time to optimize and probably had very little time before GDC. It was cool to see both in action.

    Fair enough, you didn't say 30fps. You said it was running very smoothly, which - to me - indicates around 30fps. Very smooth certainly wouldn't be <25fps.

    But i'll let it slide in light of the confirmation that the main part of your report was inaccurate.

    from http://www.gamespot.com/news/2004/03/24/news_6092217.html

    So it seems some others noticed it was not very smooth.

    Sorry I wasn't aware of this standard. I'll keep it in mind the next time I post and didn't mean to cause a problem for you. I'm not so sure it was an inaccurate observation.

    I can fully believe it was choppy on NV40 - what I can't believe is that ATi had a part there which was faster by several degrees throughout, even at a higher resolution and more detail. Especially since the engine is looking at these cards as the minimum spec - not something you'd expect to run it at 1024x768 "very smoothly".

    Well i bet Daniel will tell us the resolutions? it should not be a secret as i guess a lot of guys seeing theses demos could tell us the resolutions in a heartbeat.
