-The maximum number of frames to be drawn per second. A value of 50 is pretty
-good. If your computer is pretty old, can get away with decreasing this value
-and still have reasonably smooth animation. You can set this to a very high
-number to effectively render as many frames as is possible, but the actual rate
-could be limited by vertical display synchronization, depending on the X11
-driver and settings used. You should not set this option higher than the point
-where the vertical synchronization effectively limits the draw rate or else the
-game may not be able to update the physics on schedule which could actually
-significantly lower the quality of the animation.
