6.4.2 Performance Bar

The performance bar gives an idea of the current scene rendering performance (frames

per second).

• Current (CUR): Shows how many frames per second the scene will render at in On

Air mode. The number should be above 50 ( PAL ) or 60 ( NTSC ), according to the

rate that has been specified in the Output Format section.

• Maximum (MAX): Shows how many frames per second the scene can render

at without waiting for vertical retrace. The higher the maximum value, the more

performance is left. If the maximum value is reduced to below 50 or 60, the scene is

not rendering in real-time.

• Vertices (VER): Shows the number of vectors in the scene.

• AllocTexSize (TET): Shows the total allocated size of texture memory.

• TexSize (TEC): Shows the size of the currently used texture memory.

• Animation (ANI): Shows how many microseconds all active directors and

animation channels take. This indicator is linked to the yellow bar.

• Matrix (MAT): Transforms each container in the scene into world coordinate space.

This indicator is linked to the cyan bar.

• Z-Sort (Z&C): Refers to Z-sort and Culling, and sorts all containers for correct

transparency drawing and determines if containers are visible in the current camera

view. This indicator is linked to the pink bar.

• Video (VID): Shows how many microseconds video input (live video texture) and

video output take. De-interlaced video inputs take longer time than progressive

and interlaced. The only way to improve this value is to use a faster system. This

indicator is linked to the red bar.

• Rendering (REN): Shows how many microseconds it takes to render all objects on

the screen. A faster graphics card will improve this value. This indicator is linked to

the blue bar.

• Script (SCR): Shows the consumed time in microseconds from all active scripts.

This indicator is linked to the dark green bar.

• Plugin (PLU): Indicates how much time in microseconds all active plugins spend in

each render cycle. This indicator is linked to the orange bar.

• Idle: Shows available resources in microseconds the renderer has available. This

indicator is linked to the light green bar.
