The new feature added with update 1.2.3 that introduced the option to enable HDR calibration is currently broken. It creates a ton of input lag and what feels like a significant frame rate drop when enabled. While I appreciate the effort you put into trying to implement HDR into the game finally, it needs fine-tuned to not have that impact. Other games that I've played, such as Monster Hunter World, have an in-game HDR setting that I can actually use. It doesn't impact gameplay in those other games, and ultimately does what HDR was intended to do. I don't expect an immediate fix, but I would like to know that my voice is actually heard and that the problem is currently being investigated. I'd love to get the most out of my experience playing Destiny on a PS4 Pro with a 4K television, and this would go a long way in making that happen, if it functioned properly. Please acknowledge that it is a problem, at the very least.
