Camera: Pentax 645Z
OS: Win 10 Pro 64
PC: Surface Pro 4: 8 gig, i7, quad core.
Problem: Poor processing speeds.
Notes: PhotoLab 1 was processing images at the rate of 2/minute. Version 2 processes the same images at 3.16 minutes per image. Nothing has changed except the version of PhotoLab. Why is this happening?
