What do the different antialiasing options mean?
• In the 10.xx+ drivers, there are just four antialiasing options: • Off (no antialiasing) • 2x • Quincunx Antialiasing(tm) – GeForce3 only • 4x The further down the list, the higher the quality of the antialiasing but the greater the slowdown. Quincunx will also cause the image to be slightly more blurry than the other two methods, but will roughly give 4x quality with 2x performance. • In the pre 10.xx drivers, there were more options: • For OpenGL there are three options to pick from: • 1.5 x 1.5 • 2 x 2 [LOD bias] • 2 x 2 • For Direct3D there are eight options to pick from: • 1 x 2 • 2 x 2 (low detail) • 2 x 2 • 2 x 2 (special) • 3 x 3 (low detail) • 3 x 3 • 4 x 4 (low detail) • 4 x 4 • The higher the two numbers, the better the quality of the antialiasing, the more memory required and the greater the slowdown. • The [LOD bias] and (low detail) options mean that mipmaps are stored at the resolution that the game is actually displayed at – otherwise mipmaps are stored at the resolut
