If the game world physics DON'T map to the rules, then, as another poster noted, if the players have their characters make tactical decisions based on the rules, not on the presumably different understanding of the world their character has, they're metagaming.
I find that more unsatisfying.
I'd rather have the people living in the world understand the rules by which it works and act accordingly. This doesn't mean they talk of 'classes', 'levels', and 'hit points' -- but it does mean they know that sometimes, a single man is tough enough to kill an army single-handedly, that a well-trained thief can evade any mundane guards or traps, or that if you leave a man's head attached to his body when you kill him, a moderately skilled priest can grill the corpse for information.
