I've been trying to get HDR to work properly for the past 40 minutes. I've tried all the usual tricks. When I first booted the game I could not turn on HDR Mode. For me to change the option I had to close the game and turn on Play HDR games and apps in my windows display settings. Now the in game option can be changed but everything is washed out no matter what settings I use.

Any tips for enabling HDR mode on PC?

The title menu is definitely washed out, but if you go into the HDR settings, you'll see the game looks fine.
