I played the map and i figured out that lights change the game a lot. I didn't see any big fps change.

The dark areas of mirage became bright and bright became dark. That means that Palace, Window/Jungle and other places that in normal mirage was dark now are light.

The problem comes when you go from dark places to light. Like connector. You go from A to connector and the floor is "burned" (too bright) for a while.

That changes also the awp spots. Window from mid is too clear and white. And Palace and Jungle spots are also too bright also. That means, that you come to an easy target.

Its a nice map and still possible for matchmaking, but i think that it needs some improvments to bright areas. Maybe is they become more dark.
