I'm exclusively shooting Fuji X-T1. My config: Win 7  - Quad dual core i7 2.7GHz  - 24GB RAM  - Nvidia GeForce GTX 780   Bought Affinity f. Win yesterday. After 3 hours of frustration I consider this program completely useless, at least in my workflow.   Issues encountered so far: Opening a Fuji raw (.RAF) file takes 30 seconds. The histogram is compressed at the far left, rendering the image way too dark (example attached). Can not resolve this using the develop sliders. More often than not the program becomes unresponsive for 5-10 seconds after touching a slider.   No solutions found in the help manual.   - Frank
