I always thought it to be the other way around. If you assume that we are living in a simulation, then gravity might well be an artifact of a simulation that runs on localized, loosely coupled nodes. Because when you have mostly empty space, with low interaction, then the simulation is able to run at full speed, but the more particles you have interacting at close range, the slower the simulation gets as the local workload increases. In this model the force called gravity would not be the source, and time dilation one of it's effects, but instead time dilation caused by interactions is the cause and the gravitational force is what we experience as the result.
