For instance, Remedy Entertainment had a huge presentation on their approach to multi-scale Global Illumination in Quantum Break. However, from the slides it seems like the game could be running at a 720P frame buffer.
However, it should be noted that some effects such as Screen-Space Reflections and Screen-Space Ambient Occlusion could very well be running at a lower resolution than the actual screen resolution. Moreover, even if that was the case there is still ample time for Remedy Entertainment to increase it, since Quantum Break is due on April 5, 2016 as an Xbox One exclusive.
Still, would you be disappointed if Quantum Break didn't run at 1080P? Let us know in the comments.
