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.
