Radius of full-detail voxel terrain around you (16 m per chunk). Higher costs memory and loading time.

How far low-detail terrain reaches.

How many background threads build the terrain you see (Normal, 2; Medium, half this computer's processor cores; Max, all of them), and how fine distant terrain is (Normal a little coarser, Max finer). More loads terrain faster and shows more far away; less leaves the computer more room for other things.

The game fills the screen when you click into it (Esc leaves full-screen and asks whether to leave the world; Stay goes back).

How far generated voxels may stray from the true surface; smaller is more detailed and slower. Only development servers honor it.

Off: tools for mining and blocks to place aren't drawn in your hand (you dig and place by hand); weapons, food and the like still are.

How far from you grass blades grow (0: none, just the texture). Farther costs more drawing.

How tall the blades are, from half their usual height to twice it.

How much of the grass grows in patches with blades and texture; the rest is plain ground.

How much the wind moves the grass (0: still).
