Duron 800
Abit KT7A raid v1.0
256MB PC133
SBLive Value
Geforce 2MX 32MB
HD,DVD, etc

and my games ran fine. I upgraded to a Athlon XP1700, updated the
BIOS, and noticed signifacent stuttering. Turns out that it was not a
sound card problem or anything like that. There is hard disk activity
just for the first couple of minutes of play that then seems to settle
down.  I have tried reducing the AGP Aperture size from 128MB to 26MB,
no success.

anyone any ideas ??

PS also a problem on Return to Castle Wolfenstein demo

1. Reduce sound hardware acceleration down a notch or two
2. Latest video drivers from your video card manufacturer or if the card
supports the native drivers--from the Nvidia website
3. Latest via 4-1 drivers from the motherbaord manufacturers website or from
the chipset manufacturer

   Good Luck,

0. What OS are you running?  Anything after WinME requires a lot of RAM/Disk
Space just to get the OS going comfortably.
1. When was the last time you defragged the hard drive?
2. How much free space is there?
3. Does your hard drive have a built-in cache?
4. Do you have a properly sized swap file?

I don't think its going to be related to either of the other two
suggestions. Its more likely that your system didn't detect or install the
BUS Mastering IDE controller driver for your hard disks, that is on your new
motherboard.

On your system, go into device setup, and have a look at your IDE
controller. You should be able to drill down to your hard drive(s) and it
will show if they are running PIO or DMA mode. My best is you'll find they
reverted to PIO mode when you installed the new motherboard. This would
explain your symptoms perfectly.

With the driver controller operating in PIO mode, there are two downsides.
The first is that disk activity will chew up a lot of CPU time - more than
50% when thrashing as opposed to less than 5% in DMA mode.

The 2nd downside is that PIO mode is interrupt driven. This means that your
system is generating an interrupt for each and every hard drive call. As
these interrupts are non-maskable, you'll get stuttering on all your
applications when the hard drive is active.

To resolve this problem, read your motherboard manual, and establish what
brand of IDE controller is used. Go the web site of that manufacture and
download the driver. These days, most manufactuers have an all in one type
driver installation package that will automatically detect and install the
correct IDE driver for your motherboard.

Good luck,
Tim

    Have you locked your Windows swap file at a fixed number?  Have you
tried the opengl fix, available, I "think" on racesim central?  Have you
disabled FSAA, Anistropic and any other graphic enhancement?  Have you
over-clocked your vid-card?(if so try resetting to the default speed)
Have you tried using enditall2 to shutdown the various background programs
that are running?
Turned OFF force feedback?
   good luck

Glad you found a solution ;-)

Get yourself some more RAM for Xmas ;-)
