128 bits ?
LOL
I knew that some SGI boards supported 64bits which is monstruous.
128bits is just... monstruously monstruous

I know, but they have a programmable framebuffer, means you can assign as much components you like to each channel, as long as you don''t run out of framebuffer memory. So you could even get a 256bit depth buffer, but I don''t know if there would be much room left for your r,g,b image On the other hand, with 1GB framebuffer memory, there is some room to play around. I *love* those machines, unfortunately only at work, I would like to have such a thing at home...

and AFAIC the GeForce family supports 32bits depth buffer (if you don''t use the stencil buffer).

Hmm, I think it will still return a 24bit depth buffer + 8 unsused bits, AFAIK it''s hardwired on the board. I''m sure the GF2 does that, pretty sure the GF3 as well. But I''m not sure about the GF4, could be that you can get a real 32bit buffer there.
