[Value] D3DPTEXTURECAPS_NONPOW2CONDITIONAL [Meaning] 
D3DPTEXTURECAPS_POW2 is also set, conditionally supports the use of 2D textures with dimensions that are not powers of two. A device that exposes this capability can use such a texture if all of the following requirements are met. The texture addressing mode for the texture stage is set to D3DTADDRESS_CLAMP. Texture wrapping for the texture stage is disabled (D3DRS_WRAP n set to 0). Mipmapping is not in use (use magnification filter only). Texture formats must not be D3DFMT_DXT1 through D3DFMT_DXT5. If this flag is not set, and D3DPTEXTURECAPS_POW2 is also not set, then unconditional support is provided for 2D textures with dimensions that are not powers of two. A texture that is not a power of two cannot be set at a stage that will be read based on a shader computation (such as the bem - ps and texm3x3 - ps instructions in pixel shaders versions 1_0 to 1_3). For example, these textures can be used to store bumps that will be fed into texture reads, but not the environment maps that are used in texbem - ps, texbeml - ps, and texm3x3spec - ps. This means that a texture with dimensions that are not powers of two cannot be addressed or sampled using texture coordinates computed within the shader. This type of operation is known as a dependent read and cannot be performed on these types of textures.
