Improved colors, enhanced shadows, removes yellowish tint, and a much clearer image overall.
- Install Reshade (download here: https://reshade.me), select HorizonForbiddenWest.exe
- Select DirectX 10/11/12
- Skip 'select preset to install"
- Install every shader (uncheck all -> check all top right)
- Finish the installation, then drop the .ini file from this mod into the main directory of the game (where the .exe is)
- Run the game, wait for the Reshade prompt at the top of your screen, press the HOME key, and select ClearVision.ini from the dropdown list (see image)
- (Optional) Depending on your display settings, you might need to tweak the white levels. Look towards something that should be white and see if it's either too blue or too yellow. Go into the Reshade settings (Home Key) and scroll down to 'LevelPlus.fx'. Increase the highlighted slider if your whites are too blue, decrease it if it's too yellow (see image). The same can be done if your whites are too red or green, just play around with it until it works with your display.
I don't have HDR, so this Preset might not look that good if you have it enabled.
