= Power of 2 =

The numbers 2, 4, 8, 16, 32, 64, 128, 256, 512, etc. Usually this is used to describe the [[Texture|texture]] sizes that an [[Engine|engine]] requires in order to make good use of video [[Memory|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.

+A texture that is not powers of 2 (e.g. 33x24) may be simply loaded into graphics memory as-is (on modern hardware), or it has to be padded up to the next pow2 size (to work with texture compression), or the game engine may stop with an error message that it needs to be fixed.
