I found that there is an ALi Chipset problem with DirectX V8.1 when
installed under Windows 2000 (and XP). When running the Dxdiag tool the
"AGP texture acceleration" is grayed out showing this acceleration is not
enabled. (Note also that if Microsoft Netmeeting remote active desktop
sharing is enabled then no DirectX hardware acceleration is possible.)
This is how you enable AGP texture;
1. Get RivaTuner V2, and make sure it is Release Canadate 11 or 12.
2. Ensure you have the lastest Nvidia Detonator xx.xx drivers.
3 Update your AGP driver should haven't already done so. If you have an ALi,
then get the 1.90 AGP driver.
4. Extract RivaTuner into its own folder, then run it.
5. Go to the PowerUser tab, disregard the warning, then look at the bottom
for the folder icons. You want the second one from the left which when
selected displays "Open matched Detonator database." Click it.
6. Once it loads, find the fifth line, it should say, "NVIDIA Detonator
xx.xx w2k(even if you have XP) System."
7. Once found, scroll down to "EnableAliAGP." Right click it, click the
lighted bulb, and make sure that "1" appeared in the right-hand "Value"
column. Exit RivaTuner and reboot.
8.Once rebooted, initate a directx diagnostic and you should find that you
can enable the AGP texture acceleration.
