can directx11 do that with my girlfriend's panties too?

[Santiago Ontanon]

well, you can do anything eve without DX. The point is how many things does DX handle for you. The new thing here, is that in DX 10 and earlier, when there were transparent objects, you as a programmer, had to sort them so that the furthest one was drawn first. This was a problem, since sorting uses a lot of CPU. Now, DX handles this for you (hopefully in hardware), so, this is much faster and easier to do.

Please, tell me.

What music is it?

So game industry finally can keep up with Dreamcast?

The Sega Dreamcast games console included hardware support for automatic OIT.

I doubt we're going to find out the music title/author. People have been asking what it is for the past 3 years and apparently haven't got an answer. I'm sure it is just some original AMD mix like from all their other demos.

[Tomasz Stepczynski]

yeah, what music is it??

[Brunold2505]

music??



[SystelCyrus]

No thanks, DX11 is rad as hell.

You realise how much ribbing you're going to get from that comment?

Yeaaa.... except that the operating system really only has about a 2% impact on gaming performance if you dont have shitty hardware that cant even handle the operating system. And openGL has done some cool things but still you cant honestly say it has as much potential as dx11.

well, basically this was not possible before in real time. It uses a fragment based depth sorting technique with, in this example, up to 64 layers. Most cpu based techniques only sort objects or perhaps triangles which is not enough to display all possibilities correctly.

Doing something like this on the cpu would basically mean software rastarization and shading.
