Installing and configuring RBDoom 3

= Downloading
https://github.com/RobertBeckebans/RBDOOM-3-BFG/releases

= Installing
Installing RBDoom is fairly easy, just drop everything from the archive into your game's root folder (steamapps/common/Doom 3 BFG Edition/)


= Tweaking
Alot of graphical stuff has been added into RBDoom and it could hurt fps, so I recommend disabling all of the new stuff.

r_useSSAO "0"  --  Screen Space Ambient Occlusion implementation in RBDoom. Example with SSAO on: http://imgur.com/5uja3Kq  ++  SSAO off: http://imgur.com/esHj99Q
r_useFilmicPostProcessEffects "0"  --  Post proccess effect implemented in RBDoom. Gives your image a blueish tint. Example: http://imgur.com/SChE8Gb
r_useHDR "0"  --  HDR Lightning implementation in RBDoom. Example with HDR on: http://imgur.com/vObbm4A  ++  HDR off: http://imgur.com/esHj99Q
r_useShadowMapping "0"  --  Soft shadow mapping. Chugs fps really hard. Example with SM on: http://imgur.com/Jw84blB  ++  SM off: http://imgur.com/gS1ZTvE . As you can see my GPU usage raised from 2.5-4 to around 14-25. But since I'm using AMD GPU, situation on Nvidias could be better.


Also, for some reason, disabling most of the new functions will bug out lightning and some parts will look bright and it is known issue. Alpha Labs 2 for example: http://imgur.com/ky4fCXE
You can play around with r_forceAmbient command to adjust light to your preference, but, sadly, it's just a workaround (thanks, Ravyx_ !)

Tweaks with autoexec.cfg

Given that 120fps makes physics a bit weird in the BFG Edition I recommend speedrunning it on 60fps. However, if you are like me and play on a CRT on 85hz, 60 fps makes it looks choppy. So in order to sync your fps with refresh rate and also disable autosaves at the beginning of each level that lose a little bit of time each segment (don't do it until you get to a certain level where this actually matters), create a notepad file and paste the following:

set com_disableAutoSaves "1"
set r_displayRefresh "85"
set com_enginehz "85"
set bind F1 com_enginehz "60"
set bind F2 com_enginehz "85"
set g_fov "120"

Then save that file as All Files and name it autoexec.cfg and put it in your "DOOM 3 BFG Edition\base" folder. Obviously, you don't have to use the exact numbers that I do. Use the refresh rate that works for your setup. The command com_enginehz is used to alter the fps and the 2 bind commands are the binds I used to change my fps for the Delta 3 bridge jump because of crappy rail physics on 85. The last command is your field of view.
