Doom 3 was written using a custom OpenGL driver with extensions. It's
Carmack's version of OpenGL 2.0. It adds complex shader support, per
pixel lighting, fragment programs, etc, etc, a lot of the same feature
set. The two API's both use the same hardware; the hardware provides a
baseline set of features that the API can implement. However, Doom 3's
OpenGL was able to get many features working in software on older
hardware as well.
