RAGE II was integrated into several Macintosh Computers, including the first revision of the Macintosh G3 (Beige), Power Mac 6500. ATI also shipped a TV encoder companion chip for RAGE II, the ImpacTV chip. ![]() Drivers are also provided in operating systems including Windows 95, Windows NT, the Mac OS, OS/2, and Linux. ![]() OpenGL drivers are available for the professional 3D and CAD community and Heidi drivers are available for AutoCAD users. The chip also had driver support for Microsoft Direct3D and Reality Lab, QuickDraw 3D Rave, Criterion RenderWare, and Argonaut BRender. The second-generation PCI-bus compatible chip boosted 2D performance by 20 percent and added support for MPEG-2 (DVD) playback. The 3D Rage II chip was an enhanced, pin compatible version of the 3D Rage accelerator. Its graphics processor was based again on a re-engineered Mach64 GUI engine that provided optimal 2D performance with either single-cycle EDO memory or high-speed SGRAM. The second generation Rage (aka Mach64 GT-B) offered roughly two times greater 3D performance.
