Anything of use in the k6-2+ datasheet? https://www.amd.com/system/files/TechDocs/23542a.pdf Thanks! Most 3DNow instructions are just early variants (designed to work with MMX registers) of integer instructions that were later included in SSE or SSE2. If you know SSE it should be easy enough to …

Any help from 3dmark? They advertised support for these instructions. Hmm, probably not - unless the source is available for the tool. Although one of the pdfs in the archive RetroGamer posted is very helpful, was almost exactly what I was looking for. "3DNow! Instruction Porting Guide" from August …

Interesting question, whatcha tryin to do? :-) I'm working on a game engine with Windows 9x support. For some critical routines I'm also writing SSE implementations and the SSE instructions are very well documented online. For example, culing a leaf in the BSP tree with an AABB test is something …

The only official thing left is the manual for SimNow, an ancient piece of development software that used it, with the Athlon/Opteron 64-bit CPUs. https://developer.amd.com/wordpress/media/2012/10/SimNowUsersManual4.6.1.pdf And there are some archived materials here..... https://kib.kiev.ua/x86docs …

Hi there, I was wondering if anyone knew of any additional documentation for the 3DNow! instruction set (or analysis). I've found the official documentation published by AMD (https://www.amd.com/system/files/TechDocs/21928.pdf) but was wondering if anything else was floating around out there. They …

There might be some useful info here: https://fabiensanglard.net/3dfx_sst1/ MINIGL "STANDARD" Even though MiniGL was a subset of the OpenGL 1.1 standard, there was never a spec for it. MiniGL was "whatever functions Quake uses". Utility objdump running against quake.exe binary makes it easy to …

Sorry if this is the wrong place to ask, I wasn't sure which forum to post this in (please feel free to move it if so). I'm developing a game with Windows 9x support currently and an OpenGL based renderer. My understanding (perhaps inaccurate) is that 3dfx cards never really had full official …
