I'm personally don't believe at all Hikaru had per pixel lighting, besides of that more-less trusted sources like system16 https://www.system16.com/hardware.php?id=724 claims Hikaru had Phong lighting, but doesn't claims it was per pixel. in general it doesn't sounds any realistic because a) it req...

guess why it was only up to 1.9M tri/sec for Voodoo 1? have you read at least a bit manual you posted link to? ;) spoiler: it is old immediate renderer device, with triangle setup on CPU, which means to draw each triangle you'd have to write a lot of interpolation coefficients to Voodoo registers. ...

This also made dreamcast emulation quite difficult because normal hardware just can not do sorting at the pixel level like this. There are order independent algorithms out there, but they are all pretty expensive. Indeed! I took a quick look at the PowerVR2 emulation in MAME yesterday and it's very...

all the modern GPUs uses various HSR optimizations, and they are (almost) same efficient in this as old good PowerVR 2 ;) The point is that if a GPU has a theoretical fillrate, if it renders nothing but tiny polygons it is not going to even come close to that theoretical figure, even taking T&L...

by HSR usually means things like "Early-Z" test https://www.khronos.org/opengl/wiki/Early_Fragment_Test if you maybe not aware of - in canonical rendering pipelines depth test is at very end, right before writing fragment to frame buffer (with optional blending). which means fragment is f...

Okay, I believe I have conclusive evidence of Scud Race outputting more than 573,000 pixels in a frame which means the fillrate of Model 3 Step 1.5 is higher than 33 megapixels per second. Here is a frame during the attract mode that really stresses the fillrate: https://i.ibb.co/F4LhJR5y/scud1.png ...

btw, 573K pix/frame is very good for the time. for comparison Dreamcast's PowerVR2 had real fill rate up to 1.6Mpix/frame @60Hz, but it was able to process scenes with many times more complex opaque objects (up to 53Mpix/frame), thanks to HSR. Model 3 performs hidden surface removal using the z-buf...

okay, if you want more details: yes, Hikaru have x2 xtal multiplier, it supplies 83.(3)MHz clock to: "Antarctic" command processor ASIC, its SDRAM and cache RAM, and to "Europe"'s SDRAM. but, everything else - Africa, x2 Atlantis, America, x2 Australia, Europe (i.e. ASICs which ...

Hikaru GPU's chips is gate arrays from Fujitsu and NEC, and I'd bet Model 3 GPU too. At the time, it was common practice for Japanese companies to require that device components be domestically produced. PS: btw, Hikaru GPU ASICs clocked at 41.6MHz which looks like a slight improvement compared to ...

Can confirm, it's just much less noticeable when running at 496x384 which is the Model 3's native resolution. Model 3 automatically culls objects based on size and distance, optionally fading them out gradually, according to parameters specified by the programmer. This is used primarily as a perform...
