@Wolfberry:
I tested the performance of your x64 compilations with dfttest on a mobile i5 Haswell. The one named „simd128+256“ was around 10% faster than the official 3.3.5 Build, all others were 5% slower.
However using fft3dfilter with „simd128+256“ produces an access violation. As far as I know, the instruction set of haswells should be complete up to AVX-256. Did someone manage to get fft3dfilter working with this build, if yes on what system?
