Yes, yes, but you know what I mean. Camera, View Point, Player View 
whatever. And yes I know there is no "real camera", its the scene that 
moves in the opposite direction to the user input.

My original project was to implement a _software_ raycaster, so no GPU, 
no OpenGL etc. Old old early 90's style programming.

This thread is getting a bit ridiculous - just like the Lazarus Forum 
thread did. Bottom line is, the exact same code (identical, just the 
language syntax that differed) produced acceptable results with GCC and 
Java. It didn't with FPC. We all now know FPC doesn't do such a great 
job at optimisation (I know the reasons why), and that the graphics 
API's is also not to blame. So lets leave it at that.
