Doom 3 Beta Patch to Address Config File Cheating

Jason Shoulders writes "There's a discussion at Quake3World about an upcoming change in the first Doom 3 patch. Specifically, Id Software's Robert Duffy has updated his .plan file and mentions making 'r_skipNewAmbient, r_skipSpecular, r_skipBump, and r_shadows cheat protected'. This will force players to use features such as bump mapping and shadows. What settings gray the line between tweaking and cheating?"
