Re: Stencil Buffer

No matter wich method you choose, the stencilbuffer will be written at least 1.5 times completly (initial clear + 50%). Chances are, that even the z-buffer
will internally be read completly during this procedure.

The z buffer is best disabled for entering the data into the stencil. As I mentioned you can alternately not use the stencil at all, and just render to z.

Both stencil and z are optimised on current chips, so initial clear typically means zero work.
