Issue
You want to know which video card Autodesk recommends for use with the product.
Solution
Autodesk Product Support cannot recommend a particular manufacturer's video card, but there are certain features on a video card that are recommended for optimum performance. It is also a good idea to review evaluations in CAD periodicals, user groups, and peer groups to see what industry experts and peers have to say about the different video cards available for CAD workstations. The recommendations here apply to all listed products.
AutoCAD 2004 has new features such as ShadeViewPort Plotting, Gradient Fills, and True Colors, which are best displayed using video cards with the recommended features.
Following are the recommended features:
Anisotropic filtering. Advanced texture filtering technique that improves image quality for scenes with objects that extend from the foreground deep into the background.
OpenGL. Standard API for CAD and scientific applications (very important feature).
High-resolution anti-aliasing. Technique that reduces the visual impact of aliasing.
RAM. On-board memory on the video card.
Accelerated graphics port (AGP). A faster alternative to the PCI bus.
Alpha blending. Alpha channel data stores the degree of transparency, ranging from opaque to completely clear.
Graphics processing unit (GPU). Some video cards have their own processor.
Z-buffer. The area of the graphics memory used to store the Z or depth information about rendered objects. The Z-buffer value of a pixel is used to determine if it is behind or in front of another pixel. Z calculations prevent background objects from overwriting foreground objects in the frame buffer.
