The Technical Cause behind the Kotaku discovery:
When CD Projekt RED introduced the next-gen DirectX 12 render path with Ray Traced Global Illumination (RTGI), lighting luminance values in HDR calculations skyrocketed. In the original 2015 game, bloom was calibrated to simulate soft light diffusion around low-dynamic-range fire fixtures. In the Remaster, leaving Bloom enabled stacks a wide multi-pass Gaussian blur directly over RT specular highlights, causing a massive "foggy haze" over foliage, Geralt's hair, and skyboxes.
Verdict: Disabling Bloom while setting Sharpening to High restores the crisp medieval texture details, eliminates washed-out daytime skies, and prevents night torches from blinding your field of view.

For The Witcher 3: Wild Hunt, navigate to %USERPROFILE%\Documents\The Witcher 3\user.settings. Open with Notepad, locate the [Rendering] section, and paste the generated lines.
Disabling bloom gives a modest +1% to +3% frame rate bump by bypassing downsampling and bilateral blur render targets. The primary benefit, however, is image clarity and perceptual contrast.
Chromatic aberration offsets the red and blue color channels outward from the screen center to simulate cheap camera lens distortion. On fine foliage and wire fences, this introduces heavy purple/green color fringing.
Yes. Games built on Unreal Engine 4/5, REDengine, and Frostbite all use similar post-processing pipelines. You can drop any 4K/1440p game screenshot into the file picker to preview settings.
