Please note that this folder is hidden so you must enable all files view. 4) Reboot the system. 5) Windows now detects Voodoo2 card and searchs for a driver: you must specify the path of "FastVoodoo2_4.0_GE\driver9x" folder. 6) Reboot the system. 7) Voodoo2 SLI users must repeat the steps 5 and 6 for both the cards. >> Simple Procedure 0) Install MS DirectX 7.0 or above and reboot the system. 1) Click on downloaded file named "fv2_4.0_ge" and unzip the FastVoodoo2 4.0 Gold Edition folder. 2) Go in "Device Manager" --> Multimedia Devices --> Voodoo2 Accellerator: double click on this and then choice "Update driver manually". 3) Now you must specify the path of "FastVoodoo2_4.0_GE\driver9x" folder. 4) Reboot the system. 5) Voodoo2 SLI users must repeat the steps 2,3 and 4 for both the cards. [Control Panel] You can make custom adjustments to your monitor’s display settings using the driver control panel. To open the control panel: - Double-click on My Computer. When the window opens, scroll or browse until you see the Control Panel folder - Double-click on Control Panel. When this window opens, scroll or browse until you see the Display control panel - Double-click on Display. The Display Properties sheet appears - Click on the Settings tab, then on Advanced Now 3dfx Voodoo2-1000 and V2-OC tabs are displayed [Control Panel Settings and Configuration] When 3dfx Voodoo2-1000 and V2-OC tabs are displayed are visible, you will see several slider controls and buttons >>> 3dfx Voodoo2-1000 tab - Main - Refresh Rates This control allows you to adjust the refresh rates used by many games running on 3dfx Voodoo2. At the moment we are not able to activate this control so you must do manually running registry files in \Tools\Refresh_rate directory. You will not need to restart your computer for the changes to take effect. - Gamma Correction Use Gamma Correction to change the brightness levels used by 3D games. Some games may appear too dark or too bright. Each of the gamma sliders controls brightness levels for red, green, and blue as they appear in games running on 3dfx Voodoo2. Manually adjust each of the sliders, apply, and test with your game until you achieve the brightness you want. Moving sliders to the left decreases brightness; to the right increases brightness - Link Gamma Sliders Select this checkbox to chain all three of the sliders together so that adjusting one slider adjusts them all. >> 3dfx Voodoo2-1000 - Advanced Properties This dialog offers advanced checkbox settings for 3D GAME CARD II when using Direct3D or Glide. The available options for Direct3D or Glide are located in their respective box. The individual checkboxes are described in greater detail below. These settings are for experienced users. Selecting these options may cause problems with some games and hardware configurations. >> Direct3D Advanced Properties - Force Trilinear Texture Filtering for D3D apps When selected, Direct3D applications which use texture mipmapping will always perform trilinear texture filtering. Selecting this option will not impact rendering performance. - Enable automatic mipmapping for Direct3D apps When selected, Direct3D apps which don't use texture mipmapping will have mipmaps generated for them. Selecting this option may speed up rendering performance. >> Glide Advanced Properties - Force mipmap dithering for Glide apps This option will guarantee that the mip map blending will use the hardware dithering option which can smooth the transition between mip levels. This can increase the visual quality in some games. Mip levels are pre scaled texture maps that are appropriate for polygons of various distances away from the viewer. Sometimes there is are visible texture transitions in a polygon jutting out whose surface transitions though several mip levels. The dithering can soften this effect. But at a slight performance hit. - Limit Texture Memory to 2mb for Glide apps When selected, Glide applications will limit the use of texture memory to 2 MBytes for each texture mapping unit. Some (old) Glide games may not work correctly if this option is not selected - Force triple color buffering for Glide apps Triple buffering has the same advantage as double buffering (no screen tearing - looks smooth) with the additional advantage of increased efficiency (i.e. higher frame rate) in some cases. One way to describe the advantage is that the CPU and 3D card are not as tightly linked with triple buffering which can lead to some performance gains due to work done in parallel. Triple buffering takes more memory in the video card frame buffer. This does not affect texture memory. Not all games support this setting. >> V2-OC tab - Don’t Sync Buffer Swaps to Monitor Refresh Rate for Glide apps When selected, Direct3D and Glide applications will not synchronize buffer swaps with the vertical retrace signal of the monitor. Rendering performance may increase when this option is selected; however, visual tearing may occur. - Overclock slider control Using this slider one you change hardware clock: tipical value for Voodoo2 chipset is 90mhz. Please note that overclock is potentially dangerous for your card: of course, you must abundantly cooling the card before increasing clock [AntiAliasing] 3dfx Voodoo2 chip-set has ability of rendering with AntiAliasing that makes the edges smoother (less jaggies) and gives a higher image quality. Voodoo2 can only do Edge AntiAliasing: this means that aliasing-effects, that are not situated at the border of a polygon, are left untouched. Since Voodoo2 stores its rendered pixels immediately in external Ram while the antialiasing is done when the whole image is already rendered, the hardware has to read several pixels out of the external memory, to use some sort of filtering on them and store them again in external ram. So AA involves read, modify and write operations. Because accessing to external memory reduces memory bandwidth and steals it to the other rendering actions a drop in the number of fps occurs. Remember that less fill rate is less fps. >> You can enable experimental AntiAliasing support with a double click on the files "d3d_aa_on" and "glide_aa_on" for both APIs Direct3D and GLide. >> You can disable experimental AntiAliasing support with a double click on the files "d3d_aa_off" and "glide_aa_off" for both APIs Direct3D and GLide. All these files are located in \Tools\AntiAliasing directory of FastVoodoo2 4.0 Gold Edition\ package. [Set Up refresh frequency] Default refresh frequency for all supported screen resolutions is 60Hz. You can change this valute to 75Hz or 85Hz by the reg files included in \Tools\Refresh_rate directory of FastVoodoo2 4.0 Gold Edition package. [Troubleshoting] - Enabling antialiasing you can get a great fps loss because the graphic processors must execute other calculations due to algorithms for the rendering with edge antialiasing too. So please reduce the screen resolution for more balanced performance. - Voodoo2 SLI users: default FV2 4.0 layout includes V-Sync off so that flips occur as soon as possible (often at the next horizontal retrace signal). This eliminates the potentially long wait for the vertical retrace signal, but may introduce some tearing of the display image. The tearing occurs when portions of two or more frames (which represent the scene at different simulated times or viewpoints) are shown together in a single refresh of the display. If you see these visual artifacts must enable V-Sync by Voodoo2 Tweaker in GLide window (just turn on "Sync buffer swaps to refesh rate") - FastVoodoo2 4.0 GE allows a simply hardware overclock: you must remember always that it could damage the card.
