Fuad is writing a lot of words to fill those pages... RV740 will be 128-bit with GDDR5 which bandwidth-wise is equal to 256-bit bus at the same frequency.

Interesting endeavour. :D You should note though, that normal, cooking oil is prone to peroxidation and in a month or two, it'll get all sticky and also conductive. So - the only usable solution would be either having the oil in nitrogen atmosphere or having paraffin oil (saturated higher...

By integer precision you mean FX12 (48-bit)? Because that's what John Carmack was requesting for Doom 3. And NVIDIA usually listenes to him as they have the best OpenGL impementation in gaming cards. If I remember correctly the request for 48-bit color came as soon as in GF256/GF2 days... I...

Oh, cry me a reever. :P No, don't worry, I haven't.

I see. It's really a pitty, I mean a "new" generation of chip and still 4-bit subpixel precision, cheating @ even bilinear (as 3Dcenter.de showed), no software-stencil-HSR. It's just pointless... :roll: OK, no PS 3.0 no problem, but all the other "shortcuts"... :P

Thanks Thomas - it seem that either they can't or don't want to support it on the whole NV3x line. ERP - if it it's "just" clip against some Zmin/max in hardware, wouldn't it be possible to support it on any harware?

Ah so... :wink: So how would/will this affect performance on - oh, let's say - GeForce FX 5800? Isn't the whole extension/depth_bounds (=stencil HSR) software already - I mean a programmer must tell which parts to be lit.

No, at NV30 launch/in it's specs, there isn't any Ultrashadow mentioned... It has 2-sided stenciling though and 8 z/stencil updates/clock - Ultrashd. wasn't introduced until NV35. And I think, that Ultrashadow is "just" the GL-depth_bounds extension and not anything else - so ATI would just...

I know, that Ultrashadow is different from two-side stencil, two-side stencil is shading (in the real meaning of the word :)) and ultrashd. is software "stencil HSR". Why is it not possible to implement it on the Radeon? Which part/engine/proc. of GPU is performing that on GeForce (FX)?

Greetings! I was searching Google and this fine forum and didn't find anything. Would anyone know if it is to expect ATI supporting NVIDIA's Ultrashadow technology on it's R4xx boards, that now have two-sided stencil support and are presumably (not yet proven) capable of 32 stencil tests per...
