Fruitz of Dojo have recently released Quake 1.1, which offers a number of optimizations and is now a Universal Binary compatible with Intel-based Macs, as noted by Inside Mac Games. New features include: optimized the software renderer for windowed modes; windowed modes (software and OpenGL renderer) are now resizeable; the game will renderer inside the Dock document icon (instead of the application icon) if minimized; threaded CDAudio and MP3/MP4 playback; several bug fixes; and more.
