Geometry Tuning (Turbo Microcode)

The gspTurbo3D microcode is a feature-limited, precision-reduced, optimized version of the 3D polygon microcode. It uses a completely different display list organization that is more efficient, but less general.

Because of the reduced precision, the turbo microcode is not suitable for drawing backgrounds or objects with precise textures. It is designed to draw “characters”, objects that generally remain in the middle of the viewing frustum.

The following features are not supported with the turbo microcode:

Current performance measurements of this microcode are >5K polygons per frame @ 60 Hz. For more information, consult the man page for gspTurbo3D (3P).

This microcode is in it’s first release and may change.
