This is a modification for the Doom 3 BFG Edition with better visuals, sounds, monster AI and weaponhandling. It requires the Doom3 BFG Edition and doesn't work with the old Doom3 release of 2004!
!!! If any old "@UltimateHD" directory is existing, remove it first !!!
Unzip the whole 7z-Package to your "DOOM3 BFG Edition" main directory (usually at ..\Steam\steamapps\common\DOOM 3 BFG Edition)
If everything's gone right there should be a "@UltimateHD" directory in your main directory ( => ..\Steam\steamapps\common\DOOM 3 BFG Edition\@UltimateHD)
run "Doom3 BFG UltimateHD.exe" (This calls RBDoom3BFG.exe with the right parameter)
If you don't want to use the included EXE you can also create a shortcut of "RBDoom3BFG.exe" with the following parameter +set fs_resourceLoadPriority 0 +set fs_game @UltimateHD
Should look like this => "..\RBDoom3BFG.exe +set fs_resourceLoadPriority 0 +set fs_game @UltimateHD"
