=====
|
||
|
||
The *Video* page contains settings related to the emulated machine's 2D and 3D video cards.
|
||
|
||
Video
|
||
------
|
||
|
||
Video card to emulate. Only video cards supported by the machine's expansion buses will be listed.
|
||
|
||
The *Configure* button opens a new window with settings specific to the selected video card, such as the amount of installed video memory.
|
||
|
||
Voodoo Graphics
|
||
---------------
|
||
|
||
Emulate a **3Dfx Voodoo** or **Voodoo 2** 3D accelerator, connected to the PCI bus and to the video card selected above.
|
||
|
||
The *Configure* button provides the following settings:
|
||
|
||
Voodoo type
|
||
^^^^^^^^^^^
|
||
|
||
Type of Voodoo card to emulate. The following choices are available:
|
||
|
||
* **Voodoo Graphics:** the original Voodoo model, with a single Texture Mapping Unit operating at 50 MHz.
|
||
* **Obsidian SB50 + Amethyst:** a variant of the Voodoo Graphics, equipped with a second Texture Mapping Unit like the Voodoo 2.
|
||
* **Voodoo 2:** the second Voodoo model, with two Texture Mapping Units operating at 90 MHz, as well as SLI support.
|
||
|
||
Framebuffer memory size / Texture memory size
|
||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||
|
||
Amount of video memory to give the Frame Buffer Interface and Texture Mapping Unit(s), respectively.
|
||
|
||
Bilinear filtering
|
||
^^^^^^^^^^^^^^^^^^
|
||
|
||
Apply bilinear filtering to smooth out textures displayed on screen.
|
||
|
||
Screen Filter
|
||
^^^^^^^^^^^^^
|
||
|
||
Apply a filter to make the picture resemble the digital-to-analog converter output of a real Voodoo card.
|
||
|
||
Render threads
|
||
^^^^^^^^^^^^^^
|
||
|
||
Allows the Voodoo workload to be split into multiple threads. 2 render threads are recommended for host systems with more than 2 CPU cores.
|
||
|
||
SLI
|
||
^^^
|
||
|
||
Add a second Voodoo 2 card to the system, connected to the first one through Scan Line Interleave (SLI).
|
||
|
||
Recompiler
|
||
^^^^^^^^^^
|
||
|
||
Enable the Voodoo recompiler for faster emulation.
|
||
|
||
.. note:: A host CPU with SSE2 support is required for the recompiler. SSE2 is present in most CPUs made since 2005.
