Why are textures always square powers of two

Textures are not always square nor are they always powers of two. The reason why they tend to be powers of two is usually to increase compatibility with older video cards that imposed that restriction. As for non-square textures, that’s not usually a problem. To summarize:

  • Textures typically don’t need to be square - although DirectX does have a D3DPTEXTURECAPS_SQUAREONLY capability but I’ve worked with non square textures even in older hardware with no problems.
  • Textures should be powers of two because many older graphical cards still require it. The reason for that restriction was so that they could perform some optimizations to the texture mapping operations. Most modern graphic cards don’t have this restriction either.
