When fetching a graphics device from DirectX, it’s possible to request a software renderer, though until recently no such thing existed. If you didn’t know, graphics god Mike Abrash left Microsoft and had been quietly working on a software renderer – called Pixomatic – at RAD GameTools, which has been included in UT2003 for those folks who are running on older or unstable hardware. Apparently a 1GHz CPU will run the game, though with some things like shadows and some dynamic lighting turned off. Still, it’s nice for those of us who have to support older hardware (typically done via an OpenGL layer) but would like to use all the latest DirectX API.
