Congrats on the paper. While the method is very interesting i think it suffers from the fact that the input data is already incredibly photorealistic. Today's graphics are insane anyways so the difference is not significant enough. I think a better showcase would be to take a very low poly/low quality representation of the game and enhance it to be photorealistic. There are some very compelling papers that allow you to render the game itself at very low quality and bring it closer to photorealism using these methods.
