3D Spotlight : Tweaking : 3dfx Voodoo 3 Tweak guide

3dfx Voodoo 3 Tweak guide
Updated on February 2, 2001 by Thomas McGuire Page 1/8

Check for 3dfx Voodoo OR other 3D videocard prices.



Given the current state (Or lack) of 3dfx I decided I may as well update this guide for the latest 3dfx Voodoo 3 drivers that are available, given that the past version of the guide has been outdated for quite some time now. Of course, where appropriate Iíve listed alternative download links, rather than those to the soon to be removed 3dfx servers.

This guide has been prepared in Windows 9x/Me & Windows 2000 using the latest drivers.


You should start by downloading the latest drivers for the Voodoo 3 2000/3000 PCI/AGP you can download the latest from 3dfx for Windows 9x\Me, Windows 2000 & Windows NT4. If you own a Voodoo 3 3500 or other Operating System, e.g. Linux, then select the appropriate driver from Voodoo Files. Once these are installed you might also want to try the new beta drivers from x3dfx, although you must have a current driver installed before installing these. NOTE - Before you install the x3dfx drivers ensure you backup your current 3dfxvs.dll/3dfxvs.vxd (Depending on which Operating System is installed). Once the x3dfx driver is installed then replace their 3dfxvs.dll (Or 3dfxvs.vxd) with the version you backed up. This is because the x3dfx Direct3D driver is basically messed up.

You also should have DirectX 7/8.0A or later installed. NOTE Ė DirectX 7 is reportedly more stable for some users although personally Iíve not had any issues with DirectX 8 & the latest drivers do support it.

You should also install the latest WickedGL for OpenGL games, particularly Quake 3 engine games (such as FAKK 2) as it can give better performance & visual quality than the 3dfx OpenGL driver. Those of you playing older Quake 1/2 engine games may find that the 3dfx MiniGL 1.49 delivers better performance than the 3dfx OpenGL driver in those games too.


There may be some incompatibilities between the Voodoo 3 & some games. To rectify these problems there is usually a patch available for the game. Try Fileplanet for game patches.

If you are encountering issues with installing 3dfx Tools (or rather you just canít). Take the following steps.

1.       Uninstall the current (If any) 3dfx Tools installation. This is required & you should have already done this.

2.       Ensure you have the latest Windows Installer installed. The latest version is 1.1 & is already included with Windows 2000. You can download it from Windows 9x/Me here & Windows NT 4 here.

3.       Install the latest version of Internet Explorer. This is required for the installer to function correctly as well. Although you donít need the latest version it is recommended as these are better optimized than the 4.x versions.

4.       Reboot & re-attempt installation. If it still fails to install try the remaining steps;

5.       Open x:\Program Files\Common Files\, where x represents the appropriate drive letter, e.g. C. Rename the InstallShield folder to InstallShieldBackup (Or something like that).

6.       Re-attempt installation. The renamed directory will be re-created during the install procedure.

Check the BIOS guide for optimized BIOS settings that can improve your graphics cards performance & may also fix some problems that can occur. 3dfx also recommends that you Disable Ė Hidden refresh, Byte merge, VGA palette snoop, DAC snoop & any Caching/Shadowing. If you own an AMD K6 system then set K6 write allocate to enabled in the BIOS, if available.

If you are experiencing problems with an AMD based system running Soldier of Fortune try Editing the following line in your config.cfg file (located in the SoF\user\ directory). set ghl_no_texture_stack "1".
