GPU Tessellation

GPU tessellation is only available with display drivers that support OpenGL 4.0 or higher.

GPU tessellation draws curves, polysurface and extrusion object wires using a technique to generate curve information entirely on the graphics card. This can result in dramatic performance improvements for wire drawing (results will vary based on the graphics card used).
