There are so many changes that have occurred in order to improve the God of War. There are some people who are happy with its fog effect and the changes in lighting but some people are disappointed with the way that the water looks. If you would look at the water surfaces, you will notice that not everything is reflected on water.
If it would be insisted that the reflection will be evident, it will make the gameplay sluggish. If given a chance for the game to be sluggish with water reflection or fast with poor water graphics then gamers would definitely choose the latter. There are so many things that can be expected from the God of War. If you have always been a fan, you would like this even more.
