1. A device for rendering computer graphic images, including a database and geometric processor to process a plurality of polygons, comprising:

  • (a) a background rendering engine to render the polygons received from the geometric processor;

    (b) a critical item detector configured to identify polygons received from the geometric processor that have at least a portion of the polygon within a critical item region;

    (c) a critical item rendering engine to render polygons identified by the critical item detector, wherein the identified polygons are rendered at a higher resolution than the polygons rendered by the background rendering engine; and

    (d) a critical item load manager, coupled to the critical item rendering engine, to increase or decrease a critical item load being rendered by the critical item rendering engine and to match a deterministic processing time allowed.
