Doom 3 Ultra performance boost

If you click on the link above and scroll down a bit you'll see what you need to change to get more frames per seconds.

For ease, I've done the work for you. Do these changes:

**********************************

In your DOOM 3 directory, find "DoomConfig.cfg" (x:\Program Files\Doom 3\base).

Make a copy of your config first. Then open DoomConfig.cfg in Notepad.

Find the lines:

seta image_cacheMegs "32" (May be "20" on some computers)

seta image_cacheMinK "(Not sure which number thats supposed to be here"

seta image_useCache "0"

anyway, change the settings to the following:

seta image_cacheMegs "xxx" (xxx - Half the number of you RAM, so if you have 512 mb RAM, you should put 256 here, 1024 - 512 etc..)

seta image_cacheMinK "20480"

seta image_useCache "1"

**********************************

I did what that guy wrote, and I get about 60 instead of 30 FPS.

Works great for me!

Any word in there how to get a bag of money delivered at your front door?

I'm assuming you don't have money to upgrade. So dig into this game I recommend. For me it's the best online multiplayer game there is.

This game is great, truly great, and doesn't require much PC hardware PIII 600. Read how great it is here: http://internetgames.about.com/library/weekly/aawolfeta.htm

Download it here, and the patch: http://www.3dgamers.com/games/wolfensteinet/

NVIDIA FX5200 128MB card

Hey,

Do I take it that card isnt one of the ones im seeing on ebuyer for about£40-£50? I thought I would be needing a new £100+ card to run Doom 3...

Err to make this complete: you need to calculate the mink value too.. only thing is, I forgot how :) I'll update my post as soon as I remember :)

YOu don't need a super computer to play Doom3, you need it to play Doom3 with every setting on drool-mode

You don't want to buy a NVIDIA FX 5200 128 MB card if you want real high quality from Doom3. I didn't mention above that even with the Doom3 config change, the game still framedrops to 20 in an heavy battle. 30 FPS in Doom3 isnt the same as 30 FPS in Quake3 for example. Doom3 is "easy on the frames" or something I've read. Meaning it looks/feels good even in lower amount frames per second.

Just buy the better more expencive card if you want to be sure to :naughty::naughty::naughty::clap::clap::clap:

SUPER TIP 54

Decompress your *.pk4 files (found in doom3/base) to your doom3/base folder (Note: not doom3/base/pak0 etc). WinRAR works a treat.

This has the effect of reducing or eliminating slight pauses when entering new rooms (caused by the game frantically decompressing textures and shoving them into graphics memory).

If you're using any mods (duct-tape etc) you'll have to unpack those to the same place too. This will have the effect of overwriting whatever script files the mod modifies (eg the flashlight, shotgun and machinegun scripts in the case of duct-tape mod), so back those up if you want to switch back at a later point.

Running Doom 3 at 1024*756

High Quality with all advanced settings on.

There's a nice big FAQ which has lots of these kind of tips on performance boosting. I think the tips are at the bottom.

I found the correct way to calculate the proper memory cache settings:

//---------------------------- 
// Set "image_cacheMegs" to about 1/4 of your total system RAM 
// Set "image_cacheMinK", using the formulas below. 
// 
// "image_cacheMegs" / 8 = n 
// n * 1024 = "image_cacheMinK" 
//---------------------------- 

//---------------------------- 
// Assuming you have 1 GB of system RAM 
seta image_cacheMegs "256" 
//---------------------------- 

//---------------------------- 
// Then this is assuming cacheMegs was "256" 
seta image_cacheMinK "32768" 
//---------------------------- 

//---------------------------- 
// This is the most important one, if useCache isn't enabled 
// then you won't see the benefits of the other two cvars 
seta image_useCache "1" 
//----------------------------

This tip was given by Rgoer, employee at Raven software, who is currently working on Quake4

Enjoy ;)

seta com_showFPS "1"

Put that in your base\DoomConfig.cfg and you'll see FPS in your top right corner.
