A major performance increasing tweak (http://www.forumplanet.com/planetdoom/topic.asp?fid=5733&tid=1438663) has been identified for Doom 3
I dunno if it's just me, but I noticed this trick beefed up my DOOM3 performance by a lot.
In your DOOM 3 directory, find "DoomConfig.cfg" (x:Program FilesDoom 3base). Open DoomConfig.cfg in Notepad.
Find the line:
seta image_cacheMegs "32"
I changed 32 to 96.
(you can also try 128, 256...)
I got a nice boost in performance. I dunno if the tweak worked or not (maybe my machine did something wierd, have no clue), so I'm just seeing if this works for others as well, or if a different setting works better than others.
Another Tweak:
As you already know after installation the game consits only of the doom3.exe and some .PK4 files (http://boards.gamefaqs.com/gfaqs/genmessage.php?board=12608&topic=15503352&page=0). Those PK4 files includes the entire game (sounds, videos, textures etc.) in high compressed form. Normally those files were decompresse during the game. Go to your Doom 3 installation directoy and get inside the folder "Base". There are some .PK4 files you have to open each of them with WinRAR 3.3 and extract their entire contents to the Base dir in you Doom 3 installation folder (replace all files if they are any duplicates). Now you have to delete all .PK4 files in the Base folder to prevent the game to use those compressed files again. Now the game starts and runs mutch faster!
