Interview with Epic's Tim Sweeney

Well, except for Cascades, AFAIR all nV demos have been on OpenGL with proprietary extensions, so it makes sense for them not to run on other HW. But Cascades is DX10, so the limitation in this case is wholly...umm...unwarranted
I`d have loved to mess with it on a 2900.

Wasn't there some chameleon demo, with benchmark built in too, that worked on ATI (and others?) cards too?

I wish they had asked about the performance of DX10 vs. DX9, this is still an open question I think. ie is UE3 in DX10 faster than DX9? and if not, is that just a driver optimization issue or is there something more to it?
That sentence was kind of confusing, regarding the "higher grade of detail as it would be possible with Vista DX9". Is he referring to the newer driver model by mentioning Vista? Or is he saying that DX10 gives more detail than DX9 Vista, where mentioning vista is just for an apples-to-apples comparison.
This is simple. I'm going to over-simplify it, because if I try too hard I'll say something stupid. So, I'm going to make hi ssound really stupid anyway.
Look at it this way: MSAA makes lines look pretty. The accumulation buffer doesn't actually know where lines are though, only texels from the g-buffer.
That's just my understanding. I still can't sample my multisampled VSM, though, and I imagine this is much harder.
Wow, MSAA will really smack UT3's performance if it has to multisample each pass of the g-buffer. Good thing G80 is really good at this.
Lol thanks for the attempt jbizzler but I hope my understanding of hardware AA is a tad above the "makes lines pretty" level. My earlier confusion stemmed from not realizing that all subpixel geometry information is lost during the initial render to a non-MSAA (DX9) G-Buffer.
Hey guys - thanks for all the attention.

This is the twimtbpaid factor, AMD can't do anything with this.
It was also the best card available at the time (and still), and you are right, Ati can't do anything with this

What you write sounds as a good reason ,but when r300 released twimtbp dev's not choice the r300 route, they choice slow down game developent, this is why we see no real dx9 games for years.
They can do something when starting the same money hungry program, ops i forget amd has no money left, than the only hope left is they own driver team (and r650 when its not just a shrink), but driver optimisation need time, so its a loose-loose situation.
