Why do Fallout 4 godrays look so awful?

Whenever I turn on godrays in FO4, they turn whatever they touch into a blocky, pixelated mess. Anybody know why or how to avoid it? It may be avoidable at higher quality levels, but at Medium and Low godrays look hideous. Not sure why they even bothered...
 
Solution
The low and medium settings render the godrays at a much lower resolution, creating the pixellation effect. It was done to allow the God Rays to work on consoles and weaker GPUs.
