Thumbs down Will a difrent kernel give better game performance ? (unreal2004)


Hey
I've got Debian ( R 3.1 rel 0a => kernel 2.4.27-2-686 ) on a 2.4 celeron 512 mb ram intel D845GVSR ( 845 chips famaly set thingy ).

I've set things up so (rather after fideling with stuff it ended up ) that using 'startx' I get kde, but using xinit I get X with a console window .... perfect for game performance ( no hungry desktop taking up resources )

Anyhow ... I also used the DRI that intel hands out, and make install 100%
everything seems ok.

Here is the problem. Unreal 2004 looks better running on Windows 2000 pro ( please dont flame me !! ) than on my setup !! Using stats FPS I can see that there is not that much difrance between the two, but somehow it just looks better in windows.

I know intel put more effort into the windows drivers, so that does seem to have made a difrance.

I have set up a "games" run level ( a few pointers on doing this better would be welcome ! ) and now I turn my thoughts to the kernel :

The question
Will messing with/installing a difrent/patching/bribeing the kernel help ?
What kind of kernel would be the best to use for a game like UT2004 ?

Other pointers on squeezing the last drop out ?

Thanks

hmm

Well, it seems that since your complaint has to do with looks, it would help to know what your video card is and what drivers you're using for it.

To see your video card:
Code:
# lspci
To see what modules (drivers) are loaded:
Code:
# lsmod
As far as your question about the kernel thing, it would help to upgrade the kernel. But this advice could be said about anything. You have a 2.4.x kernel and as far as I understand 2.6.x kernels were designed to (and actually do) perform better with graphics than the 2.4.x does.

Definately upgrade the kernel if you have the skills. Under Debian, there is an easy way to create a "debian kernel package" and then install that package and you've installed the new kernel. You'll need to
Code:
# apt-get kernel-package
to do it.
Here is the general procedure for doing this in Debian. Here is a little bit on migrating from 2.4 to 2.6 in debian. And here is documentation on just migrating to 2.6 the olde-fashion way (non-debian).

Have the skills ? Dude .. dselect and whamo ... it took me all of 60 seconds to install and boot into 2.6.8-2-686

so these dumps are while running under 2.6.8-blabla so I think the lsmod should look difrent now than under 2.4 ... want me to boot into 2.4 and dump that to ?

I really wouldn't know about "the best kernel for gaming". If you ask anybody you'll simply get their opinion about what worked best for them.

Here's intel's support page for your graphics card. And here's a whole section on intel graphic cards on Linux. But I don't know if I could help much beyond that as I've used NVidia, who is known for supporting Linux better than any other GC manufacturer.

Maybe you should post to these guys.

An opinion would be welcome if it's the best I can get.
I know the support page for my card, and I've seen the section on intel linux blabla.... how you think I got everything installed ? I worked through those pages.

Your links titeled "these guys" ... no good, please check it 4 me.
