Hi Hank,

I would like to ask you a question about VSA-100 architecture.There is one thing that leaves me puzzled. Why 3dfx changed their texture/pipelines ratio? out of Voodoo 1 , all next chips were like
2TMU on each pipeline, which allows single pas multitexturing(for example Voodoo 3 = 1 pipeline/2TMU). So why VSA-100 didn´t follow this scheme ? it might have been 2pipes/each with 2TMU´s = 333Mpix/666Mtex. I think it would hepl performance of VSA 100 dramatically.

In this interview back in 1999 Scott Sellers says:

Quotethat it appears based on their spec sheets and functionality that the GeForce's 256 raster engine is likely 2 TNT2 pixel pipelines put in parallel. Clearly, the geometry capability is brand new for GeForce, but it appears as though the raster functionality is virtually identical to the TNT2 raster engine (except it's obviously doubled in width and they've also added cube environment mapping...

So why 3dfx did not "stitched" two Voodoo 3 pixel pipelines adding 32Bit color, High-rez textures support and T-Buffer thing

So was there any reason to change the scheme ? perhaps size of chip, or incompatibility with T-buffer, or what else

I will do appreciate any suggestion about that.

thank you
regards Daniel

Hello,

I remember article about 3dfx Voodoo 5600 early preview back in year 1999 -2000. They showed "Voodoo 5600" with Pentium III running Quake 3 Arena at 1600x1200 with 32 bit colour, maximum texture detail and trilinear filtering - all the bells and whistles.The game was also running with four sample anti-aliasing enabled at 60fps. But then later somebody proved, that it was tweaked bios and inside was actually Quantum3D board, because 3dfx didn´t finish board design yet and with Intel bridge chip the card was unfunctional.

I am not sure if it was at Comdex or ECTS computer games trade show.My question is, what graphic card was used instead of Voodoo 5600. I just can´t remember. All I konw it was some Quantum 3D board with 3dfx chips on it.

Perhaps AAlchemy 4116 ( it uses 4 Voodoo 3 chips in sli, but Voodoo 3 wasn´t able of 32 bit output and they claimed it was 32bit color in Quake test)




thanks for info


Daniel

Amigamerlin 3.1 R11 driver-set is based on SFFT Alpha 29 Direct3D core, contains a new OpenGL library and it's the first Amigamerlin release with a new dll. The installation program will correctly install to the system a dxtn.dll. This dll, which we have discuss here, it will be only a container lacking of functions (dummy file). The user should replace it with the real one compiling the source from Daniel Borca's site. Any way drivers will works well also without the replacement. We chose this solution to prevent copyright problems. Amigamerlin 3.1 R11 supports 3dfx Voodoo4 4500, Voodoo5 5500, and Voodoo5 6000 cards on Microsoft Windows 2000/XP Operative Systems.

where I can download this new file ? I have been looking on Daniel Borca web pages and I couldnt find any file with dxtn.dll name.

and should I replace it after instalation original Amiga drivers or before instalation ?

thanks

Daniel
