Some games may require more VRAM to render textures at higher resolutions. VRAM (Video Random Access Memory) īe careful though, DirectX 7 and older applications can fail to launch if the emulated VRAM is set higher than 256 MB.

However, the only full D3D9 compatible card is the Internal 3D Accelerated card. All other virtual video cards have full hardware acceleration and capabilities, including 'Transform & Light'.

The virtual SVGA card exposes only software capable rendering (2D rendering) to the application. 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 other four non-dgVoodoo card types give specific emulated ATI/nVidia/Matrox driver versions and capabilities. This option allows for the selection of internal virtual 2D (SVGA) and 3D accelerated cards. If dgVoodoo is not needed anymore or just temporarily, without removing dgVoodoo's DLLs this option will disable dgVoodoo's DirectX wrapper. When an application loses focus, it may be desired to make the application go into an inactive state.ĭirectX settings. The 3Dfx splash screen is seen when an application starts, disabling this option prevents this animation from playing. Z-fighting can be better avoided with a 16-bit depth buffer, however artifacting can occur. If V-Sync is enabled, games that run too fast stabilize at the maximum frame-rate of the monitor used, however some games may need certain synchronizations of frame-rates to work properly. This option only affects Voodoo 2 cards, this should always be left disabled. Shows the 3Dfx watermark in-game when enabled. Only some games require accurate emulation of the PCI bus, so in most cases PCI bus emulation should be left disabled. When enabled, the virtual 3Dfx card will have PCI bus speeds emulated as closely as possible.Įmulation of true PCI access should theoretically never be disabled but there can be possible degradation of performance when left enabled. Since Glide uses a linear curve by default, the gamma level might not match the default or one's taste and can look visually detracting.
The amount of TMU texture memory is adjustable.įorcing bi-linear texture filtering can cause artifacts.Ī gamma correction curve can be set through the Glide interface when enabled. Texture Management Units (TMU) allow for multi-texturing management. Some applications determine what resolutions are supported by looking at how much on-board memory there is. No texture memory is stored on the onboard RAM, but instead it is processed and managed by the Texture Management Unit(s) (TMU). The amount of emulated video memory of the selected video card can be changed with this option. 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. 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. This option allows for the selection of 3D accelerated cards that use the Glide rendering API.
