@pauls @halide i’d take a guess that even though the 16/17 Pro and likely Kino’s engine could probably handle the larger cube sizes easily, there is a trade off on app performance to keep things running smoothly for users on older less powerful hardware. TBH honest, unless you have a professional reference/grading monitor set in a controlled lighting environment (like a post production studio), 99% of people would not even notice the difference.
