It’s buried now but look at the “FPC Graphics options” thread from a few days
ago and spanning back weeks I think. After all that I still failed to get a
clear answer I could understand well but some poor loop optimization and
floating point division was causing a ray caster example written in Java to get
low single digit frame rates where the same code ran 40+fps in Java and C.
There seems to be some changes in FPC 3.1.1 but I’m not sure what changed. Some
one else may correct what I said but feel free to take a loop. Bottom line for
me is I’m nervous about loops in highly optimized low level code now but that
may be unfounded.
