I have downloaded this and followed the instructions to place it into the Doom 3 folder, and use it to replace the orginal doom3.exe file.
The problem is, when I try and open the cracked file, I get a blue window that says:
Unknown command 'vid_restart'
idRenderSystem::Shutdown()
Shutting down OpenGL subsystem
...shutting down QGL
Couldn't load default.cfg
