Like the title says, FPS will drop depending on what area of the room the player stands in. This bug occurs for several rooms other rooms but this post will only show an example of the boss room. Currently, the final boss room has a fine line when FPS issues start occurring. I don't have the most powerful device for the game but the frames dropped by around half.

From that line to the back of the room(Where the players enter the room), there is the FPS issue. This issue has been reported before although I have yet seen a reply from someone at bungie.
