I've been noticing that my system gets poor 3D performance compared to
the systems of others and havent been able to lick the problem just yet.
I have am AMD 2800XP, KT400 mobo, 1gig corsair ram, maxtor 7800rpm
120gig drive, ati radeon 9800 pro, winxpsp2, etc. Everything is in
tip-top shape with latest drivers and stable as a windows system can
get. I ran a popular benchmark and after comparing my score of 27,000 to
others I'm getting radeon 9600 performance out of an 9800 card. Even
when overclocked I still do not get anywhere near the scores most
9800pro owners get; they usually around 40,000 while I'm stuck at
27,000. In real world gaming my computer lags behind others when it
comes to graphic settings compared to someone with a simiiar system.
In the BIOS I have AGP as the primary video interface, 256 meg arpeture,
and everything looks good to me in there. Perhaps I should knock it
down to 128 as the card only has 128 megs of video ram?
256 is too high, I believe the aperture should be set to no more than the
installed ram amount
Is there something else that could be causing this poor score? The RAM I
have is pretty cheap and the one 512 module is only rated at 100mhz but
works fine at 133. The mobo is stable but I do know of one issue with
AGP. At 8xAGP the 3D video apps crash almost instatly. I have no
problems at 4x. I have the latest VIA drivers for the AGP interface. I
also have the latest ATI drivers. My understanding is that no card could
ever make use the 8x interface so using 4x shouldnt affect performance.
This is a homebuilt system using an MSI kt400 board which has a lot of
performance options.
I'll bet that no one else that your comparing your system to, is using a MSI
board.
I'm guessing either im missing something obvious
or the agp chipset on this might be messed up, although it is not giving
me any errors unless I run it at 8x.
Are the other rigs NOT using 8x also?
Anything else I might be missing?
I'd appreciate any suggestions.
