A developer writing about retro PC graphics says affine texture mapping alone was not enough to reach acceptable framerates on an Intel 386. The original affine renderer had to be written in very tight x86 assembly because it ran thousands of times per second just to render a single frame, highlighting how limited early 90s hardware was for 3D games.

Why now: Retro computing and demoscene communities enjoy deep technical breakdowns of how programmers squeezed performance out of early PC hardware.

• [2/2] using affine texture mapping alone wasn't enough to hit acceptable framerates on a 386. the person who wrote the original affine renderer had to write it in *very tight* x86 assembly because it was being called thousands of times per second just to render one frame.… · vga256@tomodori.net · 12
