The ladder is samples per display pixel: 2X is a canvas root-two wider and taller, 4X one exactly twice the size. Every edge in the projected picture softens with the silhouettes — the tileset's own texels are quads in a perspective view and cross the pixel grid at the same arbitrary angles — so the diorama reads smoother rather than sharper. The most expensive row in the mod, so it is OFF by default and **FULL** leaves it alone |

 ## VR
 
 The **VR** options row (OFF / ON, off by default) drives a PCVR headset
 through OpenXR on Windows — SteamVR, Oculus or WMR.
 
+The **SMOOTH TURN** row appears under it while VR is ON (OFF by
+default): ON turns the right stick into a continuous turn instead of the
+45° snap. The snap is the default deliberately — a software turn moves
+the world past a head that did not move, which is the most reliable way
+to make somebody ill in a headset — but it costs continuity, so the
+choice is yours.
