Confusion over the relationship between surfaces and textures
Author
So a surface is like a background and a texture is the sprite, correct? Or why is it you sometimes use surfaces and sometimes textures when doing something 2D?
EDIT: "lemme see if I got this" is not a suitable subject line

Textures are just collections of surfaces, typically in decending size order for the purpose of mip-maps.
Surfaces can be copied around, but really shouldn't if you want good performance. Textures can be applied to geometry and are intended for the actual rendering.
Assuming you're talking about Direct3D then you should be using textures or ID3DXSprite for all 2D rendering unless you have a specific requirement that cannot be met by either approach. This latter case is unlikely.
