@file settings.h
This file contains settings (or setting hints) for the game. Values here can
fine tune performance vs quality and personalize the final compiled game. Some
of these settings may be overriden by the specific platform used according to
its limitations. You are advised to NOT change value in this file directly,
but rather predefine them somewhere before this file gets included, e.g. in
you personal settings file.

be droped, but the game logic will still be forced to run at this speed, so
the game may actually become slowed down if FPS is set too high. Too high or
too low FPS can also negatively affect game speeds which are computed as
integers and rounding errors can occur soon, so don't set this to extreme
values (try to keep between 20 to 100). FPS also determines the game
simulation step length, so different FPS values may result in very slight
differences in game behavior (not very noticeable but affecting demos etc.).
