Common Glide & DirectX graphics settings
- The resolution and anti-aliasing options are relevant to both Glide and DirectX.
Display Resolution
- See Widescreen resolution for relevant information.
- See Scaling for information on scaling resolutions.
- Forcing a specific resolution can break UI menus, graphical effects and much more.
Resolution | Description |
---|---|
Unforced | The application will control the resolution. This is the safest and the default option. |
2x, 3x, 4x | Dynamically scales the current resolution set in-game, which is calculated by the wrapper. |
Max | The maximum available resolution will be used. |
Max ISF | The maximum available integer multiple of the apps resolution will be used. |
Max FHD | The maximum available resolution will be full HD (1920x1080); 1080p. |
Max FHD ISF | The max available integer multiple of the apps resolution will be used; FHD (1920x1080); 1080p. |
Max QHD | The maximum available resolution will be QHD (2560x1440); 1440p. |
Max QHD ISF | The max available integer multiple of the apps resolution will be used; QHD (2560x1440); 1440p. |
Resolution | Resolutions from 640x480 to 1920x1080 can be forced. |
Anti-aliasing (MSAA)
- See Anti-aliasing (AA) for relevant information.
- Forcing anti-aliasing can cause graphical artifacts.
MSAA Level | Description |
---|---|
Off | Forces anti-aliasing off. For DirectX applications, this only affects DirectX 8 and above. |
App driven | The application controls the anti-aliasing. Safest option. |
2x, 4x, 8x | Anti-aliasing (MSAA) will be forced to the selected amount. |
Configuring Glide
3Dfx card
This option allows for the selection of 3D accelerated cards that use the Glide rendering API.
Some applications and games may need an older card model or older Glide versions, due to the advancements of Voodoo 3Dfx technology made over time.
The different video cards also presents bias to games which may lock particular rendering capabilities and properties to certain 3Dfx cards and versions of Glide.
VRAM (Video Random Access Memory)
The amount of emulated video memory of the selected video card can be changed with this option.
No texture memory is stored on the onboard RAM, but instead it is processed and managed by the Texture Management Unit(s) (TMU).
Some applications determine what resolutions are supported by looking at how much on-board memory there is.
Texture Management
Texture Management Units (TMU) allow for multi-texturing management. The amount of TMU texture memory is adjustable.
3Dfx card | VRAM Min | VRAM Limit | TMU | TMU Memory Size |
---|---|---|---|---|
Voodoo Graphics | 2 MB | 4 MB | 1 | 1024 kB, 2048 kB, 4096 kB |
Voodoo Rush | 2 MB | 4 MB | 1 | 2048 kB, 4096 kB |
Voodoo 2 | 8 MB | 12 MB | 2 | 2048 kB, 4096 kB |
Voodoo Banshee | 8 MB | 16 MB | 1 | 2048 kB, 4096 kB |
Other greater | 2 MB | 128 MB | 1-3 | 1024 kB up to 65536 kB |
Force bi-linear filter
Forcing bi-linear texture filtering can cause artifacts.
Disable mipmapping
Disables mipmapping. Self-explanatory.
Miscellaneous
Enable Glide Gamma Ramp
Disables or enables the gamma ramp from Glide.
Force emulating true PCI access
This option when enabled, will emulate accessing the 3Dfx card (which is virtual) via the PCI bus as close as possible. This option should never be disabled, but there can be possible degradation of performance when enabled. Only some games require accurate emulation of the PCI bus, in most cases PCI bus emulation can be disabled.
3Dfx Watermark
Shows the 3Dfx watermark in-game when enabled.
Pointcast Palette driver build
This option only affects Voodoo 2 cards. This option should always be disabled.
Force V-Sync
When V-Sync is enabled, games that would run too fast stabilize with a frame-rate cap, however some games may need certain synchronizations of frame-rates to work properly.
16 bit depth buffer
Use only when Z-fighting occurs. Z-fighting can be better be avoided with a 16-bit depth buffer, however artifacting can occur.
3Dfx Splash screen
The 3Dfx splash screen is seen when an application starts, disabling this option prevents this animation from playing.
Enable inactive app state
When an application loses focus, it may be desired to make the application go into an inactive state.
Configuring DirectX
Disable and passthru to real DirectX
If dgVoodoo is not needed anymore or just temporarily, without removing dgVoodoo's DLLs this option will disable dgVoodoo's DirectX wrapper.
Videocard
This option allows for the selection of internal virtual 2D (SVGA) and 3D accelerated cards.
The other four non-dgVoodoo card types give specific emulated ATI/nVidia/Matrox driver versions and capabilities.
The different video cards also presents bias to games which lock particular rendering capabilities and properties to owners of a real ATI, nVidia or Matrox card.
The virtual SVGA card exposes only software capable rendering (2D rendering) to the application. All other virtual video cards have full hardware acceleration and capabilities, including 'Transform & Light'.
However, the only full D3D9 compatible card is the Internal 3D Accelerated card.
VRAM (Video Random Access Memory)
The amount of emulated video memory of the selected video card can be changed with this option.
Be careful though, DirectX 7 and older applications can fail to launch if the emulated VRAM is set higher than 256 MB.
Some games may require more VRAM to render textures at higher resolutions. There are also other advantages to increasing the VRAM.
Video card | VRAM Min | VRAM Limit |
---|---|---|
dgVoodoo Virtual SVGA Card | 16 MB | 128 MB |
dgVoodoo Virtual 3D Accelerated Card | 16 MB | 2048 MB |
GeForce 4 Ti 4800 | 64 MB | 256 MB |
ATI Radeon 8500 | 64 MB | 256 MB |
Matrox Parhelia-512 | 128 MB | 256 MB |
GeForce FX 5700 Ultra | 64 MB | 256 MB |
Texture Filtering
- See Anisotropic filtering (AF) for relevant information.
- Forcing texture filtering on an application can create glitches or break rendering effects.
- GPU driver-forced global or per-app anisotropic filtering will override the dgVoodoo2
Anisotropic
setting.
Filtering | Description |
---|---|
App driven | The application will control the texture filtering quality. This is safest and the default option. |
Point sampled | Point sampled texture filtering will be forced. |
Bilinear | Bilinear filtering will be forced. The four nearest texels to the pixel center are sampled. |
Linear mipmap | Nearest-neighbor sampling from individual mipmaps whilst linearly interpolating the two nearest mipmaps. |
Trilinear | Trilinear filtering will be forced. Bilinear filtering on the two closest mipmap levels are applied and are interpolated. |
Anisotropic | Ansiotropic filtering of up to 16x can be forced. |
- Mipmapping can be disabled with the "No mipmapping" option below the filtering settings.
Window Behaviour
Application controller fullscreen/windowed state
Unticking this option will force the specified screen mode in the General tab.
Disable Alt-Enter to toggle screen state
Disabling this option is recommended if the application already handles its window state via Alt+Enter.
If this is not disabled and Alt+Enter is used for an application that utilizies it, then dgVoodoo will conflict with the application.
Miscellaneous
Bi-linear blit stretch
When enabled, linear filtering is applied for stretched copying between 2D surfaces (DirectDraw only). Linear filtering is much nicer generally, but can cause artifacts. Especially with colorkeyed blitting. Early hardware did not support or apply point sampled blitting, which can end up with very pixelated results.
Force V-Sync
Vertical syncing is forced in all cases whenever the application window draws. However there is a performance penality when enabling V-Sync.
Fast video memory access
Fast video memory access can speed up games like Toy Story 2, but can also completely break others.
Fast video memory access is applied for locked surfaces.
Only recommended to use if an application is performing slowly, despite system specifications
Apply Phong shading when possible
Phong shading is applied in place of Gouraud when it is possible. This option only has effect when the application uses the fixed function vertex/pixel pipeline and pushes all the work of the vertex transform & lighting (T & L) to Direct3D when rendering primitives. Do note though, using Phong shading requires much more GPU power than default shading.
dgVoodoo Watermark
Disabling the watermark will remove the dgVoodoo text in the application that is using the wrapper.
HUD and interface scaling on high resolutions
- Many games don't scale their interface and HUD which end up being very small or even unusable on high resolutions. By instead forcing high resolution using dgVoodoo, this problem can be fixed in many games.
- Some games (for example Machines) are rendered correctly when resolution is being forced, however the mouse cursor movement remains restricted to resolution set in the game video settings making the game unplayable.

Game specific configuration files
- If there is no dgVoodoo configuration file in the same folder as the game, dgVoodoo will use global settings.
