Hello.
I am currently running gentoo with the lastest nvidia drivers from ~x86 portage, and something seems very wrong with Doom3.

I am running at high detail, 2x antialiasing on a Geforce 6800GT.

On Windows:

On Linux:

Bumpmapping seems downsampled to around 64.

it is most noticeable in the second screenshot. If that can be of any use I use Twinview with Xinerama extensions.

Some info:

supernaut@ewigkeit supernaut $ glxinfo | grep "direct" | awk '{ print $3 }'

Any ideas what might be causing this? Quake3 seems to run fine

could it be directx? isnt that a windows only thing? if it was made with that i dont think it would look as good on a linux box since iut doesnt have that.

Uhm.. well, Doom3 is an OpenGL game, one of the rare true gems in this category. John Carmack is for portability, so it should at least look as good regardless of your platform... I've seen screenshots of Doom3 on linux, and it does not look as bad.

Doesn't look bad at all to me... That could be due to the fact i'm still running a GeForce 3 TI 200 64 meg in this rig.

looks to me that the linux one has no antialiasing, and some lighting incompatibilities.

mr_daemon

Dec 13 2004, 04:42

Well, lighting really is fine, what seems crappy is the bumpmapping, it seems downsampled.

linux just isnt a good gaming Os at all imo (and no, im not flaming.)

mr_daemon

Dec 13 2004, 04:50

Linux is decent as a gaming OS. If your game is written using OpenGL.

are you sure you have doom set up correctly in linux?

also what is the output to glxinfo

mr_daemon

Dec 13 2004, 18:18

Well it would be extremely hard to have doom 3 set up "incorrectly."

And as for glxinfo, you can see up there that DRI _is_ enabled:

CODE

supernaut@ewigkeit supernaut $ glxinfo | grep "direct" | awk '{ print $3 }'
Yes
supernaut@ewigkeit supernaut $

if you really need the full glxinfo output I can post that but you know...

Could it be that you need to set some options for your graphics card in xorg.conf or XFree86Config

mr_daemon

Dec 14 2004, 01:51

Well, I highly doubt that as well, there isn't much to do in xorg.conf besides setting nvagp to 1 and my dual screen setting with xinerama.

I heard somewhere that twinviwe mess with hardware acceleration..
Read here
Its from fedora forums but it may help you
Doom3 ran with the same quality than windows on my machine when I installed it on FC2, now with FC3 I havent installed many games

mr_daemon

Dec 14 2004, 03:01

WELL I officially fixed it.

I disable texture downsampling and other things, and noticed there was a setting named image_ignorehigh "1". i turned it off, and everything is back to normal. Performance is even better than windows apparently...

There most definitively is a bug with quality detection...

So, you fixed it by....

making changes to the doom config file?

You could have just copied your config file from your Windows partition to your local users DooM III config file. But you have it fixed anyway!! gj!
