Remedy has addressed Quantum Break's less than auspicious launch on Windows. It was surprising that a company with history on PC should turn out a substandard port, but fixes are in progress.
If you suffer from stuttering, you'll be relieved to hear Remedy has it figured out: "a major rounding error introduced into our refresh rate predictions on shipping". A patch will arrive in the near future, as will the addition of a 'quit' option—always useful—and direct control over settings like film grain.
The full breakdown also confirms suspicions about how Quantum Break is rendered—it's not native 1080p. À la Xbox One, images are constructed from four buffer images rendered at two-thirds of the chosen resolution with 4xMSAA. "Engine assigns input geometry samples from 4xMSAA rendering into shaded clusters in order to maximize covered geometry while keeping the performance on acceptable level by reducing expensive shaded samples." In other words, it's permanent. On the other hand, the framerate lock will disappear in May when Microsoft allows developers to disable vsync.
