Believe it or not, I'm attempting to make an action-driven game with ruby.  Is there a way to get the time in milliseconds since the program started, or something similar?  I've tried using Time.now.to_f, but all too often that value will be the same in two consecutive update calls, causing jumps in motion and "infinite" fps readings.
 
Also, will extending calculation-heavy classes to C up the performance enough to make a fairly sophisticated game run?  I'm talking like maybe a NES sports game as far as complexity goes.  For example, a vector class has about 15-20 methods that all do a few simple computations.  Would C significantly speed that up or would the fact that ruby still has to make the calls bog it back down?
