A free mod for Witcher 3, by BeastBlaze.
During cutscenes, the mod raises the most post-processing settings to their highest quality possible and after the cutscene is complete, the post-processing returns to the user's previous settings.
The mod targets the performance hit most especially during cutscenes and FPS is not an issue given that the scene is not action-packed. Cutscenes Graphics Enhanced mod works well with the lighting and texture mods as well as with Tweaks, Enhanced Graphics Settings, and Magical Graphics Settings.
Other features of the mod in post-processing outscenes include blurring, depth of field options, motion blurring, light shafts, blooming, underwater reflections, vignette options, anti-aliasing, and SSAO: HBAO+
