Why WinQuake exists and how it works

A deep dive into WinQuake's architecture reveals why id Software created a Windows 95-native version of Quake. The article explores performance benchmarks showing WinQuake achieved near-DOS performance (within 6%) by bypassing Windows virtualization overhead. It examines the multiple rendering backends (GDI, DirectDraw, VESA, VGA) enabled by SciTech's MegaGraph Graphics Library and WinDirect technology, which allowed direct hardware access in Win32 applications. The piece also covers audio backends (DirectSound vs WinMM), input systems (DirectInput vs legacy APIs), and the various performance modes available through command-line flags.
