Video game development is a fluid process; things change all the time through development until launch and beyond. One thing that changed with the upcoming Spider-Man PS4 game due out next week was the size of puddles in one particular scene. This has led to claims that developer Insomniac Games in some way downgraded the game's graphics, and now the developer has spoken up to stress that there has been "no downgrade."

This issue picked up steam thanks in part to this popular Reddit post (via IGN) that shows more puddles in an older, E3 trailer for Spider-Man and fewer puddles in a newer video. Writing on Twitter, Insomniac confirmed that it changed the size of the puddles, but stressed, "There's no downgrade at all." Some believed that Insomniac had to scale back the graphics to meet performance demands, but it appears this is not the case.
