# ALLEGRO\_VERTEX\_CACHE\_SIZE(3alleg5)

Allegro 5 API

## NAME

ALLEGRO\_VERTEX\_CACHE\_SIZE - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro_primitives.h>
  #define ALLEGRO_VERTEX_CACHE_SIZE 256
  ```

## DESCRIPTION

Defines the size of the transformation vertex cache for the software renderer. If you pass less than this many vertices to the primitive rendering functions you will get a speed boost. This also defines the size of the cache vertex buffer, used for the high-level primitives. This corresponds to the maximum number of line segments that will be used to form them.
