There are such theories, even with mass requiring more calculations. So when there is mass nearby, you need to make more calculations, which slows down that speed in that place. Slowing down speed in medium typically provides refraction/bending of light, so maybe bending of path of light/mass (aka gravity) is due to computational complexity.
