Texture Loading Problem

Is there anyway to set a texture's dimensions so they do not scale to a power of 2? Right now I am using the D3DX_DEFAULT_NONPOW2 flag to do this when creating the texture but apparently this does not work with all cards. It is making the textures all distortorted on cards that don't support it. Is there any way around this?

If a card doesn't support it, there's not much you can do.

If you're using the texture as a texture for a 3D mesh, the extra size shouldn't really matter. If you're doing it in 2D, I can see how it can be a problem.

When writing 2D programs, I dealt with this problem by manually resizing the texture up to the nearest power of 2. But rather than stretch the image, I just filled the extra pixels with black. I then used alpha blend or alpha testing to remove the extra black pixels.

Yeah, I will do that in my future games. The thing is, i only became aware of this after I completed the game so it is going to be hard to go through all the images and resize them. If I manually set the size of each image I load, would that work the same? Instead of using D3DX_DEFAULT_NONPOW2 for the sizes I just fill in the sizes manually?
