SK...
Here's what he should do:
1. Reinstall the AMD 761 AGP chipset drivers.
2. Set the BIOS to 4x AGP.
3. Make all the other tweaks and settings as outlined below.
4. Go to the Windows98SE "Virtual Memory" manager.....and de-select
allowing Windows to manage "Virtual Memory"....follow the "Virtual Memory"
settings below.
If he does all this.....he'll have the highest FPS, best picture/graphics
quality......his "system" can produce. And, set the VM as indicated...the
"frame stutter" will end.

PS: I'm assuming he has done the "basics"...and made sure that no major
components are sharing IRQ's???
**************GeForce 2 (MX, GTS, ULTRA) and GeForce 3 - "Tweaks and
Settings" for N4****************
Desktop Color: Set to 16-bit color for N4 and all games.
DirectX: Make sure you are using a DX 8.0 compatible driver (Nvidia Ref
drivers versions 7.0 or higher, 12.0 or higher for GF3 cards)
For N4: Run OpenGL (not D3D) in "XXXX"x16 (you must use a screen res
compatible with your CPU speed and ram).
Monitor: Make sure you have downloaded the latest drivers for your
monitor...DO NOT USE "Plug and Play" Monitor drivers! Set your refresh rate
at the highest setting you are allowed for your monitor at the specific
screen res you want to run N4 at.
Advanced Settings Tab For OpenGL:
In The Scroll Down Box:
Enable Buffer Region Extension (checked)
Allow the dual planes extension to us local video memory
(checked)
Use fast linear-mipmap-linear filtering (checked)
****all others are unchecked****
Default Color Depth for Textures: Always Use 16 bpp
Buffer Flipping Mode: Use page flip
Vertical sync: Always off
Full Scene Antialiasing Method: Always off (try 2x or Quincunx
for GF3)
Use up to [62] MB of system memory for textures in PCI mode
Mother Board BIOS Settings:
Video BIOS Shadow = "Disabled"
Video BIOS Cache = "Disabled"
Palette Snoop = "Disabled"
AGP Turbo (or x4) = "Enabled" (if your mobo supports
it....disabled or 2x or 1x if it does not)
PnP Aware OS = "Yes"
AGP Aperture Size = 128 mb (only if you have 128 mb or
more...which you should)
Resources Controlled by = "Auto"
Assign IRQ to VGA = "Yes"
Windows Virtual Memory Settings:
1. Go to the Windows Virtual Memory settings box (right click
"My Computer" -select- "Properties" - select- "Performance Tab" -select-
"Virtual Memory" button on lower right side of box.
2. Select "Let me specify my own Virtual Memory settings."
bullet.
3. Set the Minimum and Maximum to the same value....this is
very important! [This will keep the swap file from being resized all the
time by Windows.]
4. Set the value at something between 2x and 4x your physical
RAM memory (remember the Value is entered in KB, not MB). Example: With 128
MB ram, at 2.5xRAM = 320 MB (entered as: 3200 KB in the box).
5. Restart your computer as Windows requests.
6. Go back and make sure the settings you made are still
there....and check this regularly. Windows has a *** habit of deleting
this stuff all the time....and taking back over the management of VM. I've
never been able to figure out a "pattern" for when Windows does this....I
just know that half the time....when I check this.....Windows has taken back
control of VM and I have to reset it to the above settings.
***DOING THIS WILL SOLVE THE N4 FRAME STUTTER......assuming you have no
other "issues" with IRQ sharing and so forth. I also found this solves the
same problem in GPL...when using the high-res***pits and race tracks.
