I've got really poor performance when playing Doom 3. My PC spec is as
follows:
2.4Ghz Pentium 4 (400fsb)
Asus motherboard with 4x AGP
512MB of DDR 333 (PC2700)
40GB ATA133 HDD
Radeon 9700 Pro 128MB
All FPS from timedemo:
I was initially using Catalyst drivers 4.5 and this gave me 31.6 fps in 640
x 480 at low quality. Bumping it up to 1024 x 768 at high quality dropped
the frame rate down to 26.9.
I upgraded to the latest drivers 4.8 and this increased my 640 x 480 at low
quality to 44 fps and 1024 x 768 at high quality to 29.2 fps. This is still
very low.
I've tried the trick of changing the cache image setting in the config file
to 128 and to 256 but this hasn't helped.
I think the problem lies in one of three places:
1. My system can handle 533fsb except the processor so I could upgrade to a
2.4GHz Pentium 4 (533fsb) - Cost £85
2. Add more memory either another 512MB or a whole 1GB extra - Cost £45 per
512MB
3. My motherboard only supports 4 x AGP but the graphics card is 8 x AGP.
Upgrade motherboard to another that is 8 x AGP but is still compatible with
my socket 478 CPU and DDR 333 RAM - Cost £40 ish.
I've done a bit of research and it seems like the issue of the 4 x AGP and 8
x AGP is not an issue because the bandwidth limit of the 4 x AGP port will
never be reached so 8 x AGP will be very little noticable difference if any.
I've attempted to overclock my system to see if having a higher fsb will
improve the frame rate. After overclocking to 420MHz fsb (CPU speed rises to
2520MHz) I get a fps of 29 at 1024 x 768 at high quality (dropped fsp of .2
this is a bit weird).
I then overclock again up to 440MHz fsb (CPU speed rises to 2640MHz) I then
get a fps of 29.8 at 1024 x 768 at high quality.
I can thus assume that having 533MHz fsb will provide very little increase.
I found the following website and it would suggest I should see a lot more
fps:

Can anyone help me with my machine spec and what I need to do to see higher
fps? Thanks
