For simple "test" or "toy" games without animation, AI, physics, 
culling, etc, this may be true. But in my experience, when you start to 
push these things you quickly become CPU bound rather than GPU bound 
(even with a C engine) unless you take great care and spend lots of time 
optimizing your program. Using Lua instead of C for the low level stuff 
means you hit the CPU-limit faster.
