"The point is ladies and gentlemen that greed, for lack of a better word, is good. Greed is right. Greed works. Greed clarifies, cuts through and captures the essence of the evolutionary spirit. Greed, in all of it's forms - greed for life, for money, knowledge - has marked the upward surge of mankind."

Nice demo, although it is cheating. About texture loads compared to super-buffer, first well aehm excuse me but the super-buffer thing could actually also be done already on a Geforce3 with NV_pixel_data_range, EXT_pixel_buffer_object and EXT_vertex_buffer_object (so nothing really to shit your pants. Although you obviously work at ATi now you still should not try to blend people and at least play a little bit more fair). Besides VS3.0 texture loads are more more more flexible than what you could do with that.

Anyway this is getting a little bit offtopic but I must say all in all I'm slightly disappointed with the X800 marchitecture, as it really seems only a small update compared to the R300 (and the performance increasement I see is just connected to the higher number of pixelpipes and the higher clockspeed), hence even the stupid texture indirection level restriction is still there.

This type of branching has been around for along time. people have used it for over 3 years now. It only works for some situations.

Humus, thanks for your reply about the problem.

And for maturity, I guess there are many ways to say a joke, and there are many jokes to say. A simple smilies can't represent all your subjective mood and tone.
I'm not being immature. I just point out what you think is funny doesn't neccessarily mean it'll be interpreted as a joke of others.

Richteralan,
I never understood what problem you're inquiring about. The posts I saw has been answered already, unless I've missed something.

Regarding maturity, I hope people still are able to interpret smilies correctly. But given the amount of negative feedback I've recieved I'm not so sure about that anymore. The "" is IMHO a pretty obvious sign that it's a joke. I think the people that are unable to see that and get all pissed about it are the ones that are immature.

Anonymous,
yes, it has been around for a while. It has been used for implementing high level shading languages on lesser hardware, but I don't know if it ever has been used as a means to boost performance. But that's not a very interesting point anyway, what matters is that it works and is fast.

Sunray & sqrt[-1],
I've been experimenting some with scissors and clipping planes at work today. Of course the benefits goes down when you use other means to reduce the workloads too, and that's equally true for ps 3.0. But there's still a very significant performance increase with this technique, even when you enclose a bounding box of six clipping planes around the light and enclose the light in screen space with a scissor rectangle. We may no longer be talking about 3x performance boost, but still easily 30-50%.

Regarding texture lookups, well, we won't be able to do everything vs3.0 can, but we can do some similar stuff the day we get the super_buffers extension (if ever, seems to be progressing very slowly ...).
