I just finished stacking around 76 RAW canon .cr2 files with calibration frames using the new DSS, and I have to say I think it's mad fast thanks to the new SIMD vectorization (don't ask me what this is, alli know is it's faster... A lot faster, on my system atleast.)
6 MINUTES TO CALIBRATE, REGISTER, AND STACK 76 12.2 MP RAW .CR2 FILES
