Every DX10 games that will be released will play on both nVidia and ATi cards. Please support Geforce 8000 alongside HD 2000 series, please.

What about some GI on d3d9?

It s gonna take 2 years before any normal computer have dx10 cards..

I was wondering how does one use the bicubic texture filtering that has been added to the 2900 series in DX-9.
Thanks

Given the much deeper market penetration of the G80 products, does this mean that the initial DX10 titles to come, will somewhat avoid using rich and dynamic procedural environments, and thus under-utilizing the vast potential of R600 in this area... and we still haven't touched the HW Tessellator yet here, as it is not a mandatory API part, at this stage.

Well, of course they were optimized for AMD, but that doesn't mean that you could do something similar very fast on Nvidia if you were to optimize for them. In fact, I experimented with that, and sure they could be able to run the GI sample at maybe 5fps if I tune the rendering to be more "DX9 style" as a workaround for their slow GS, but that's still nowhere close to the AMD performance, plus that what's the point of DX10 if you have to code in DX9 style to make it run fast? For the HD 2900 the DX10 style rendering runs faster, as you would expect. The truth is that the G80's GS performance is poor except for trivial shaders. If you do any form of geometry amplification (which is the main motivation behind the GS in the first place) the performance drops off exponentially.

Nonsense,
The DX10 samples don't run well on Nvidia only because they are made by AMD, for AMD.
I'm sure Nvidia could make lovely DX10 demos that work just as well on their 8800.
(In fact, they do) for example: http://www.nzone.com/object/nzone_cascades_home.html

But anywho, nice to see that you've been productive, Humus!
