PowerOfTwo

= Power of 2 =

The numbers 2, 4, 8, 16, 32, 64, 128, 256, 512, etc. Usually this is used to describe the texture sizes that an engine requires in order to make good use of video memory. An example texture size would be 32x64. Textures that are not in powers of 2, like 33x24, would probably cause the engine to run slower or maybe crash.
