hello,

I installed it on the laptop Dell Inspiron 5150 with FC4, pentium 4 3GHz and ATI Radeon Mobility M9 as video card (I don't know how to see its size). The result is extremely slow, slow at loading, slow at playing.

What should I do ?

Thank you.

Are you sure it's an ATI card? My quick google search returned Nvidia Geforce FX 5200 as being the card shipped with those computers. It also said that it has only 256 MB of RAM. If that's indeed your specifications it's natural that Doom 3 will run slow in that machine. If you are using something heavy as KDE and if you don't have 3D acceleration enabled, you are lucky to even be starting Doom at all

Please, post the following:

cat /proc/meminfo | grep MemTotal
cat /proc/swaps
lspci | grep VGA
glxgears


The first command should return your amount of RAM (you can type top as well), the second your swaps and it's size and the third will hopefully return you correct Video Card. glxgear will display your fps in a given time.

Regards!

thank you Man

this is what I get in 'System Settings' -> 'Display' -> 'Hardware settings'

I found that too, and I wonder why I have an ATI card... it must be some "special" delivery, or I didn't pay attention to the possiblity to play doom3 when ordering the laptop

well, sometines I can even play in normal way, but the most of the time the image is really slow

stupid question - is it possible to install-enable 3D acceleration for my config ?

cat /proc/meminfo | grep MemTotal
MemTotal: 774292 kB

cat /proc/swaps

THANKSSSSSSSS!!!!!!!!!

Doom3 will be running good with all advanced system options turned off (shadows e.t.c.)
But the next question is how to save this settings... doom does not saves it

create file ~./doom3/base/Autoexec.cfg with the config options you want (figure them out from the Config.cfg file) and it'll keep the settings.

a decent guide for various settings is:

http://www.techspot.com/tweaks/doom3/

don't go overboard with it though as it doesnt yeild the results it claims (for me anyway as i think my system is CPU-bound rather than GFX-bound), so all i have in my Autoexec.cfg is:

seta image_useCache "1"
seta image_cacheMegs "128"
seta image_cacheMinK "2048"
seta s_driver "oss"
seta s_numberOfSpeakers "2"
seta com_videoRam (128)

i dont know what video ram you've got, you may need to check in the BIOS to see that, but here's how i work it:

seta image_useCache "1"
seta image_cacheMegs "128"
// ^ about main system ram / 4.
seta image_cacheMinK "2048"
// ^ image_cacheMegs (value/8)*1024 or summat.
seta s_driver "oss"
seta s_numberOfSpeakers "2"
seta com_videoRam (128)
// set this to your video ram amount. need to find it out.

and your glxgears fps seem very low. i get 10755 fps average, in glxgears, but only 32.7fps in doom3. my system is an athlonxp2200 ram 512mb with geforce6800 128mb. your processor is good though, so i dunno if your gfx card is up to playing doom3 really, but i dont know anything about ATI cards.
