Hello again and enjoy this brand new update which comes with an exiting new feature and various improvements.
In this new update the OpenAL-soft EFX is now vastly improved and now Audio Logs, PDA Videos and Radio Communications will use a default reverb in order to be more clear and more realistic (considering that these voices are coming from the player's suit). Also I changed the default values of Soft Shadow LOD and force Ambient (shadow transparency) in order to improve the performance and make the shadows on Doom 3 closer to the original.
Since the ROE (Resurrection of EAX) patch and with it's addon, Doom 3 has EAX Support similar to the Original Game. Now Doom 1 & 2 has this support thanks to a new script named REVERBD which allowing you to set reverbs per sector on each map.
