i just got Doom 3, and with my dual Xeon processor, 2 gigs of DDR 333 RAM, and 256 meg NVIDIA GeForce card, when i set the graphics to extreme resolution the game actually slows down a bit. it shows a popup when i set the resolution and warns me that it will take 500 meg of texture memory, but when i run the game and hit Ctl Alt Del and look at the process, Doom 3 is only taking up about 600 megs total. that leaves about 1.4 GIGS free memory. 2 Xeon processors 3.06 Ghz each, and the game slows down. i emailed support that they said it might be that the processors are executing game commands faster that the video card can process the textures. any ideas on how to get this workstation to shred apart this game. there should not a program out there (yet) that can slow this machine down. i think it might be my computer settings.

any ideas?

I got 10fps at 640x480, every thing off

Try forcing Vsync off, that might speed up gfx -> cpu transfer speed

if it is using 500 meg of texture memory then it will overflow from your video card into your system memory. This will cause a definate slow down. It has nothing to do with your processor power, but the fact that it has to retrieve textures from system memory when they are used for rendering. I suggest you get a 512 MB video card (if they are available) to fit the requirements that the warning is giving you.

I don't believe 512 MB cards are out yet but they're coming. You can't run ultra display mode on the single player levels without a 512MB card (which you're trying? See Codemonger's post) ... but apparently the multi player levels will allow you to with a 256MB card. If you can run these no problem on ultra ... then you'll know it's a memory issue. What kind of a video card are you using? I'm assuming you're using a 6800?

I understand you want your super system to 'shred apart this game'. If it supported dual processors (do you know? I haven't looked into this) and you have 512MB of real video ram ... it basically would. This assumes a high end dx9 card of course...

With the demo version, I get only 2 fps at 640x480 with everything off.

im surpised it even worked on my computer
640x480 medum detail 30fps

localmotion, you gave the answer yourself... TEXTURE memory is in your vid card... and at 256 mb there's simply not enough space which means excess data is stored in main mem

pretty impressive hardware, by the way, very useful for playing games...

<tongue *firmly* in cheek>

You can manually change the config files and explicit how much video memory should be used.

Surf the net for doom3 configuration / command line options

There seem to be some good benchmarking apps here that you could test

They're geared towards hardcore gamers and next-gen machines, so...

can i just say that i am getting the new 3D Labs 512 MEG video card in 2 weeks. mwaahahahahah. mwaahahahah. dual RAMDAC 400mHz processing units too. so let me just update:

dual xeon 3.06 Ghz processors 512 K cache with hyperthreading: overclocked
2 GIGS DDR 333 Mhz RAM with dual channel
512 MEG video card with dual RAMDAC processing
mindsoft utilities tweaked system with XPlite reduced XP professional

and when i get my PHD and am working at a pharmaceutical company in the end of 2006:

PB version 5-6.0
QUADRUPLE AMD 64 Opteron 3.0 Ghz processors with 1Ghz frontside BUS
32 GIGS of DDR 3 ECC REG RAM
1 GIG video card with DUAL RAMDACS released by 3D Labs in late 2006

mwahahahahah. mwahahahahah.

localmotion34 has gone power mad!!! 8O

So where do you live, again?

speaking about big numbers:

I can't believe you still work with 32bit CPU's - how lame is that


Ok, ok, I go back into my corner and play with my superfast 949999987 Hz AMD Duron laptop with 262143998 bytes of ram (some of them got lost...) and 65536000 bits of video ram.

Has anybody experience with nLite?

How stable is a system tweaked with XPlite or nLite etc.?
