To have FPS showing in the corner by default:
in xx\Doom3\ folder, find Doomconfig.cfg
Open in notepad.
Scroll down to "seta com_showFPS "0""
Change the 0 to a 1 and FPS will show by default all the time, save having to type in colsole, for anyone interested.
EDIT: Seems it *MAY* have all been run at 800x600, even thought I set Doom 3 to 1024x768. I did restart at many stages, so they change should have taken effect.
I'm getting 42.4fps at 1024x768, which is still better than my first runs of 39.1, whether they were at 800x600 or 1024x768.
I don't know what happened though
I am further experimenting changing more settings, but whatever happened, I think most of the tests are at the same resolution, so there is DEFINATELY improvement for a 9800 user.
OK, I've finished doing all I think I'm going to do for now.
My Doom 3 tweaking results, all done with the same system and only the changes as noted:
AMD Athlon XP-M 2500+ @ 2266MHz (17x133)
1GB (2x512MB) PC2100 DDR
Sapphire Radeon 9800 non-pro overclocked to 403MHz core 316MHz (632MHz) RAM
Onboard sound (Realtek)
ABit NF7 (non -S) v2.0
1024x768 or 800x600, I don't know which @ medium quality
Demo used: "timedemo demo1" at console.
Doomconfig.cfg file:
seta image_cacheMegs "xx" (Default 20)
To change cachemegs setting.
Test 1
cachemegs 20
Cat 4.7's
Main runs: 39.1 and 39.1 fps
Test 2:
cachemegs 128
Cat 4.7's
Main runs: 44.6 and 44.4 fps
Test 3:
cachemegs 128
Cat 4.7's
pk4 files unrarred to Doom3\base folder
Main runs: 44.8 and 44.7 fps
Test 4:
cachemegs 256
Cat 4.7's
pk4 files unrarred to Doom3\base folder
Main runs: 44.9 and 44.7 fps
Test 5:
Cat 4.9 betas (from Guru3D.com - says 4.8 in Cat control panel?)
cachemegs 256
pk4's unrarred
Main runs: 47.0 and 46.9 fps.
Results:
Unrarring pk4 files did nothing much escept take up disc space
Changing cachemegs from 20 to 128 did wonders, but anything above that showed no effect, I'm not sure what lower values may do, othes have found cachemegs to have no real effect.
Using the Cat 4.9 beta from Guru3D over the Cat 4.7's improved performance.
After all tweaking, frame rates improved: 20%
With no additional overclock, or any different components, this was all using my existing system and I got 20% extra performance out of it, for free.
Hope this helps people out.

"Main runs" means discounting the first run, and taking any 2 runs that were fairly close.
Some are 2nd and 3rd runs, some are 3rd and 4th runs, as MSN Messenger messed up the second runs once or twice.
I can post first run numbers if you want, but they are not too reliable either, as during one first run, MSN messenger popup messed up the run.
