What Exactly Is A Draw Call

The gang at PC Perspective has an article posted today that explains just what a draw call is and what it can do.

Mantle, Vulkan, and DirectX 12 all claim to reduce overhead and provide a staggering increase in "draw calls".

After everything is configured and bound, one of a few "draw" functions is called, which queues the task in the graphics driver as a "draw call".
