Overall great app, but it is INSANELY CPU hungry. It doesn't support GPU acceleration in any way (at least not OpenCL), do not worry, it WILL hog up all your resources no matter how much cores does your desktop CPU has. 6 cores? Lol, just leave it with your ancient hardware! It will lag like crazy while just bulk changing the easiest settings (like White Balance). 8 cores? Not enough. 12 cores? It will eat through all your 24 threads with ease while bulk applying settings, may easily hang for minutes on end. 16, 24 cores? Now your PC is strong enough to use it semi-swiftly. I'd love to give it 5 stars if it was optimized. AND this does NOT have any kind of auto white balance which is just insane if you think about it. Any kind of algorithm that could calculate white balance for your RAW photos would be invaluable.
