I know what the answer is going to be, but I’ll ask it anyway: Is DXT compression supported in CUDA? DXT is the DirectX texture compression algorithm. See here: http://en.wikipedia.org/wiki/S3_Texture_Compression
No, the DXT texture formats are not currently supported by CUDA (and before you ask, neither is mipmapping or cube maps).
It would certainly be possible to implement features if there was enough developer demand. but they didn’t seem a high priority given the kind of applications that CUDA is designed for.
On a related note, our texture tools do use CUDA to accelerate off-line compression of DXT files:
