Batched 1D FFT
Is anybody aware of a library for doing batched 1D FFTs in DirectCompute? D3DCSX does not appear to support batches. I need a library that I can use in a closed-source commercial application. It doesn't have to be free but it does need to be similar in performance to CUFFT.

Just wonder, how big are the FFTs that you need? Is it complex-to-complex?
