It has been a lot of speculation on Internet that CD Red Project has downgraded some effects for the final build on every platform including PC.
Event the guy who work for the game admited, i got the conversation from Dualshockers:
"Lighting is absolutely crucial! And making an open-world game with always changing lighting conditions was a huge challenge. Every light in the game is dynamic, even some effects cast lights too, you can walk up to almost every light source and extinguish or ignite its flame, nothing is baked!
We ended up not using Global Illumination, light bouncing and reflecting… this is similar to what I mentioned previously with visual effects, an area where things keep getting better every year, but these really cool solutions are still far too expensive to use in a complex game. So to add more detail to the lighting, the whole world is covered in “lighting and reflection” probes, that analyze the surrounding area and light it accordingly. It does a pretty good job." -(Jose Teixeira CD Red Project Visual effect artist ) -

I also include some comparison graphic made by someone on other gaming forum, i don't know if it's true or not legit or not, i am not an expert on this but the guy have some point that need to be considered.
