Days Gone supports "windowed," "fullscreen," and "borderless."
Non-16:9 resolutions are supported. For example, on my 16:10 screen, many games have black bars on top and bottom, but not Days Gone.
There are no artificial FPS limits, and V-Sync can be disabled completely.
Field of view can be adjusted up and down from its default of 70°. I felt like 90° was the optimum for me, but the setting goes up to 100°.
"Render Scale" is your typical upscaling option. The setting range from 10% to 200%. Only the game's rendered 3D graphics will be affected, the HUD and texts will always be rendered at the native resolution.
You may choose between the following quality presets: "Low," "Medium," "High," "Very High," and "Custom"
Motion blur can be turned off—thank goodness.
Plenty of additional settings let you fine-tune the individual graphics details.
