The latest update for Quantum Break includes an option to disable the reconstruction tech, via which the game was rendering at a lower resolution and was then upscaled to your desired resolution. And below you can see for yourselves what this game looks like in 4K without that annoying tech.
Quantum Break is beautiful. No, let me rephrase it. Quantum Break is perhaps the game with the best visuals we’ve ever seen. Its lighting system is spectacular, it’s packed with really high-quality textures for pretty much all surfaces, its shadows and ambient occlusion effects are stunning, and its reflections are sweet.
