The Darkness [BLES00058]

Just reduce the value to your desired one in the text section of your patch.yml. for me 0.3 works just fine.

Code:

Lower Exposure:
    Games:
      "The Darkness":
        BLUS30035: [ 01.03 ]
    Author: illusion, Aphelion
    Notes:
    Patch Version: 1.0
    Patch:
      - [ bef32, 0x10AC2F0, 0.6 ] <-- change your value here (for blus)

I set vblank frequency to 120 (the internal resolution setting does not seem to change anything.), so the game runs mostly at 60 fps (RTX 3090, Ryzen 5900X). I have finished the game on RPCS3 Version: 0.0.15 Alpha (THE DARKNESS [BLES00058]), patch 1.03).
