Software renderer

Stub

This article or section is a stub. You can help by expanding it.

A software renderer, such as those available in GoldSrc and id Tech 2, uses the CPU to render 3D geometry, instead of a GPU. A 3D application using a software renderer can be considered to be running in software mode.

The GPU is still used for processing the 2D image generated from the software renderer, but no 3D hardware is used.
