Whats the relationship between SwiftShader, Cider, and Cedega?
TransGaming’s Cider and Cedega technologies allows games built for Windows® to be run on Mac OS® X and Linux® systems. Cider and Cedega includes not only support for the 3D graphics APIs used by games, but also every other major API they require – sound, input, window system integration, etc. The graphics technology in Cider and Cedega converts Direct3D® API calls to OpenGL® API calls, in contrast to SwiftShader, which compiles and executes the graphics commands itself.
