This ambition comes with certain drawbacks though. Stuttering is an issue, and on close testing, the game's performance rests within the 20-40fps range - and typically more towards the lower end. This is with v-sync engaged at all times, but it's clear the push for top-grade facial capture and lighting really cripples the frame-rate at points, with some of its lowest drops to 20fps occurring during close-ups.

The lack of a 30fps cap doesn't help either, and frame-rates go up to 40fps at rare points. This means the frame-time switches to 16.67ms, but without consistency at any one number, it simply means fast camera motion shows judder as the refresh switches between rates. In theory a cap at 30fps would help, but in its current state long segments of Until Dawn unfold at 20fps - particularly in cut-scenes with all characters on-screen
