From DoomWiki.org
→Differences with Doom 3
* Flashlight-projected character shadows are disabled.
* More light sources in the levels.
* Textures are stored with a more visually faithful compression format, [http://www.nvidia.com/object/real-time-ycocg-dxt-compression.html YCoCg-DXT5] (the . The textures are not in higher resolution)with the exception of some face textures like Dr.Betruger, Elliot Swann and the main protagonist.
* Some video setting options cannot be turned off anymore, with the rationale that more recent hardware does not need to sacrifice those settings for performance; this includes anisotropic filtering, shadows, specular maps, and bump maps.
* PK4 archives are not supported, meaning any mods made for the original game cannot be loaded. The game has been modified to store levels and meshes in a compact binary format which the original version of the game cannot read, packed inside a streamed resource file format adapted from {{wp|id Tech 5}} called the ".resources" file, which now contains binarized formats of textures, models and sounds assets.* RoQ video format is now replaced with proprietary [https://en.wikipedia.org/wiki/Bink_Video Bink Video] format.
* The Martian Buddy lockers code website www.martianbuddy.com doesn't exist anymore, therefore player gets the lockers code in an e-mail.
* In Level 05 (Alpha Labs - Sector 1) in the Hydrocon Condenser room there's a staircase that in the original Doom 3 is missing one stair and collapses underneath you when you walk over it. In the BFG Edition the stair is not missing and the stairs do not collapse.
* Theresa Chasar, the crying npc in Level 09 (Enpro Plant), has now tears in her face.
