Microsoft’s Project Scorpio supports variable refresh rates, meaning display technology like AMD Freesync and Nvidia G-Sync are compatible with the upcoming console.
In fact, Project Scorpio already supports AMD’s anti-screen tearing technology. According to a report by Gamasutra, Microsoft is “working with TV manufacturers to try and ensure Scorpio will support” variable refresh rates “in as many TVs as possible.”
Televisions generally come with fixed refresh rates, commonly 60Hz for NTSC regions. When a GPU renders frames, it doesn’t always do so at a fixed rate, and this difference in frequency causes screen-tearing. With variable refresh rates, the display can adjust to whatever the GPU throws at it, smoothing out the on-screen action.
