The game supports "windowed," "fullscreen," and "borderless."
Non-16:9 resolutions are supported for gameplay, cutscenes are letterboxes—you can see that in my screenshots.
There are no artificial FPS limits, and V-Sync can be disabled completely.
The amount of sharpening defaults to 20 and looks good without being too distracting
"Dynamic Resolution" tries to achieve a certain FPS target and automatically adjusts the resolution scale accordingly
"Resolution Scale" is your typical upscaling option. The setting ranges from 25% to 100%. 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," and "Max." Interestingly, "Max" is not really the maximum; the settings in "Advanced" are not affected by the preset setting, no idea why.
The "Advanced" section has two more options, which we maximized, too.
Field of view can be adjusted on a separate settings page, up to 110° from the default of 75°. I found 90° to be a better choice than the default.
Motion blur is always present and can't be turned off via the settings options
To change these settings, open "GameUserSettings.ini" in "%LOCALAPPDATA%\Biomutant\Saved\Config\WindowsNoEditor\" and add a section:
[SystemSettings]
r.MotionBlurQuality=0
