Actually, there's one, but nobody has figured out how to do it. If we're in a simulation, then the computing capacity of the universe is limited. If we were to find an instance of such limitation, that would prove it.
The mediocrity argument (explained in the article) is pretty compelling, though. If we admit that such a simulation is possible, the odds on being within one are arguably much higher. It's similar to the argument against Earth being the center of the universe.
