Here is a preview how the changes look like:
id Tech 4 Engine Coding / RBDOOM-3-BFG 1.1.0 preview
December 30, 2015, 07:29:50 AM
I used the christmas holidays to add a bunch of renderer features to DOOM 3 BFG.

Here is the changelog:

- True 64 bit HDR lighting with adaptive filmic tone mapping

- Enhanced Subpixel Morphological Antialiasing
   For more information see "Anti-Aliasing Methods in CryENGINE 3" and the docs at

- Filmic post process effects like Technicolor color grading and film grain

- Fixed issues with Mesa drivers and allowed them to use shadow mapping

- Defaulted fs_resourceLoadPriority to 0 so it is not necessary anymore to specify when running a modification

- Additional ambient render pass to make the game less dark similar to the Quake 4 r_forceAmbient technique << -- this was really necessary IMHO and will be improved with automatic placed cubemaps aka IBL light probes soon

I only imlemented SMAA 1x so far. It was necessary because real HDR with 16 bit floats and MSAA didn't work well with all those post process effects like heat haze.
I went into many driver problems using MSAA.
However the SMAA code is a very good starting point for the other modes like SMAA T2x which is essentially what UE4 does.

You can download it from

Screenshots how it should look like:

Doom 3 BFG Hi Def version 1.5 (for BFG edition of game) install and run RBDOOM-3-BFG from your desktop. Higher poly models, tga textures, and effects including soft shadows (RBDoom3bfg). This version has more textures, tweaks, and a autoconfig file that kicks the image quality up all the way. Now has its own installer to make everything even easier. Install to your Doom 3 bfg directory. Note: this version fixes the install problems from 1.4 and adds a few higher poly models.

 I have added soft shadows to my RBDOOM-3-BFG fork in the last 3 weeks and you can get it from

The implementation is way more elegant and faster than my previous one from XreaL so you might have some fun with it.
It runs at solid 120 fps on my system (i7 4770K, GTX 660 Ti) so I can only advise to try it out. The entire game feels like a completely different and better game with those soft shadows.

old hard stencil shadows

new soft shadow mapping
