Does DirectX9 support 64 / 128 bit color depth formats?

Question

Does DirectX support 64 bit color depth formats? Such as Format.A16R16G16B16. I have some code that uses this format and it compiles but I does not seem to work. Note: I know my display can't show 64bit color the texture is for getting more color info into a pixel shader. If we are intrested in my motivation for this question please see these links.

Why is this 128Bit Color Format being converted to 32Bit

Answer 1

Yes it does support 64-bit and 128-bit colour modes. Whether your graphics card supports it or not is a different matter, however.

You may need to use a ps_2_a/ps_2_b or ps_3_0 profile though.
