New Radeon 9800 and Doom 3 : Need Help!

KungPowChink

Hey guys,

I just bought a new Radeon 9800 256mb for my computer solely for the sake of running Doom 3 at some nice higher end FPS.. What i was using before was my GeForce4 5200 128mb..

Anyway, so i just installed my radeon and the drivers and Direct X9, but when i go to run doom 3, i get even Worst FPS than i did when i used my GeForce.. I mean i cant even run the game at 800x600 Res.. I have no idea whats wrong, and my computer can handle the game otherwise..

P4 3.0 Ghz
1 Gig DDR Ram

Dont know why my Radeon isnt going so well with Doom 3, Can you guys help me out.? Thanks!

Try the beta 4.9 catalysts.

Doesn't it need directx 9a or b?
Acording to fraps I get 60 fps most of the time but it may drop to 45 when the action heats up.

I wouldn't recommend fast writes because it can cause instability and there's not that much performance gain, if any.

You can download some tweaked cfg files for doom 3 and radeon cards. after i put in the tweaked files i was able to play at ultra high settings with my hacked 9500 pro @ 1024x768 except for 2 points in the game. The card was overclocked to 9700 pro speeds but with your killer card you should get much better results.

You have a link to those files Komete?

all you need to do is create an autoexec.cfg file and place it in your Doom3/base folder with the modifications to config file that you want.

Like this:

autoexec.cfg

set com_allowconsole "1"
set com_showfps "1"
set com_videoram "128"
set image_downsizebumplimit "512"
set image_downsizebump "1"
set image_downsizelimit "512"
set image_downsize "1"
set image_downSizeSpecularLimit "64"
set image_downSizeSpecular "1"
set image_usecache "1"
set image_cachemegs "256"
set image_cachemink "20480"
set r_displayrefresh "70"

of course your settings may vary.
be sure to include the quotes. these are the settings I use for my 128mb 9800pro ...if this were a 256mb card I would use the following settings:

set com_allowconsole "1"
set com_showfps "1"
set com_maxfps "128"
set com_videoram "256"
set image_downsizebumplimit "1024"
set image_downsizebump "1"
set image_downsizelimit "1024"
set image_downsize "1"
set image_downSizeSpecularLimit "64"
set image_downSizeSpecular "1"
set image_usecache "1"
set image_cachemegs "256"
set image_cachemink "20480"
set r_displayrefresh "70"

or something like that.
