...just wanted to add - that using Radeon Super Resolution causes the game to first launch in a small window, which will go fullscreen after clicking on it.
I believe this is the key - this is the same behavior that used to exist prior to the 4.2.0 update.
This also explains why @lex_lutha111384 's fix works - the key has something to do with the game launching in a window that allows HDR to work properly.
However, simply running the game in windowed mode doesn't allow HDR to work properly.
This is right. If you just switch to windowed mode, from fullscreen, hdr is still dull and *. You have to launch the game in windowed and expand the screen as soon as it pops up. The other day it was working but it was bizarre. Switching to HDR and SDR was not flashing. It was just switching in real time. It looked correct though. I’m lost.
