How to speed up doom 3 on the macintosh platform
(this may also work on other platforms but I have no way of testing it)

The following .pk4 files in the folder doom 3/base can be decompressed with stuffit expander which speeds up loading of levels and access of individual files during game-play. If an update comes out and you have uncompressed the .pk4 files, you will need to delete the Doom 3 folder and recopy it from the original installation disc, before you install the update or it wont be installed properly, then proceed to uncompressing the files again.

pak000.pk4 *
pak001.pk4 becomes dds
pak002.pk4 becomes models
pak003.pk4 becomes sound
pak004.pk4 becomes textures
pak005.pk4 becomes pak005.pk4 folder~^
pak006.pk4 ~*
pak007.pk4 becomes pak007.pk4 folder~^
game00.pk4 becomes game00.pk4 folder ^
game01.pk4 becomes game01.pk4 folder ^
game02.pk4 becomes game02.pk4 folder ^
game03.pk4 becomes game03.pk4 folder~^

~ 1.3 update file
* cannot be uncompressed
^ remove word folder
