When I see a license on a project I expect that project will provide the code under that license and function fully at runtime, not play games of "Speak to a sales rep to flip that bit or three to enable that codepath".
I find it frustrating it is not immediately clear it is open core (in which case we shall never touch it as per our lawyers). So hopefully people will keep commenting on that.
From my experience, the absolute magicians in fixed point math were the 8-bit and 16-bit video game designers. I was in awe of the optimizations they did. They made it possible to calculate 3D matrix maths in real time, for example, in order to make the first flight simulators and first person shooter games.
