Achieving Peak Geometry Performance

• Triangles. Work with triangle strips consisting of six triangles (or multiples of six). Render individual triangles in groups of four (or multiples or four).

  Note that the hardware allows mixing of different lengths of triangle strips. Grouping like primitives is highly recommended.

• Quads. Work with quad strips consisting of three quads (or multiples of three). Render individual quads in sets of three (or multiples of three).

• Use glLoadIdentity() to put identity matrixes on the stack. The system can optimize the pipeline if the identity matrix is used, but does not check whether a matrix loaded by glLoadMatrix() is the identity matrix.
