I've used the mod, and I noticed some increased detail, especially when it's raining in-game, and even moreso when it's raining at night. The mod's downfall is its Depth of Field, though. When using this mod, DoF is just INSANE! Everything 50-feet away starts to blur, and the further away an object is, the more blurry that object becomes. It's like playing a game while forcing yourself to somehow become near-sighted, in desperate need of Coke-bottle glasses.
Lastly, I hate Bloom, DoF, and Motion Blur. I disable those settings in games ALL the time. To me, each of these settings completely removes game details (at least temporarily), which in turn makes a game seem far less realistic than realistic.
