Vignette in Gaming: Dark Screen Edges and VR Comfort
A vignette is a darkening of the picture toward its edges and corners. In photography it comes from lenses; in games it is a post-processing effect, applied after the scene is drawn. Developers can use it as a style choice or, as in VR, as a comfort feature.
How the effect is defined
Unreal Engine, which powers many current games, documents the effect plainly: vignette fades the image toward the edges, as if you were looking through a borderless window. A single intensity value controls how strongly the corners darken. Larger values give more darkening, and 0 turns it off. A game built on that system can have a fixed vignette set by the artists, or can expose the value to players.
Vignette as a VR comfort option
In virtual reality a vignette has a practical purpose: it darkens the edges of the view while you move, so less peripheral motion reaches your eyes, which is a common trigger of motion sickness. Meta's locomotion best practices for Quest developers (updated 17 December 2025) list vignettes that darken screen edges during movement next to blinks, snap turns and teleports as ways to move without discomfort. The same page asks developers to offer Recommended, Comfortable and Advanced locomotion presets and to make smooth turning an opt-in.
Meta's own toolkit shows how such an option is built. Its Interaction SDK has a comfort vignette setting with four levels (Off, Low, Medium, High) that reacts to turning, accelerating and moving, and newer versions draw the tunnel around your point of view in degrees, so it covers the same field of view on every headset. In Horizon Worlds build mode, the comfort settings let you turn the dark edge shown while moving on or off, or swap it for a grid.
If a VR game makes you feel unwell, look for a comfort menu with options named vignette, tunnel vision or comfort mode.

FAQ
What does vignette mean in game settings?
It is a darkening of the screen edges. In Unreal Engine the intensity value controls it, and 0 means no vignette.
Does vignette reduce motion sickness?
In VR it is used for that purpose. Meta's developer guidance lists vignettes that darken the screen edges during movement among its comfort techniques.
Should I turn vignette off?
If you want a clear image to the edges of the screen, yes, when the game offers the option. In VR, keep it if movement makes you uncomfortable.
