Why I Love Software Rendering: Quake at 800×600 on a $50 Dell

Software rendering, where the CPU draws every pixel, gives classic DOS games a sharp, gritty look that early 3D cards blurred away. On a Dell OptiPlex 380, Quake at 800×600 holds a locked 60fps—something impossible in the 90s. The catch: it needs a fast CPU and native DOS, plus a sound card, to run as intended.
