On my Radeon x800 the non-power-of-two 3d texture (e.g. dimension 18 texels) needs several seconds to draw, while a texture with dimension of 256 texels draws instantaneously. I am using GLSL to access the texture for each fragment, that is why I'm posting here (maybe a problem of GLSL then?). The 1D and 2D textures make no problem even if not power of 2. Does it get any better with non-power-of-two 3D textures on newer cards?
