Define Details
GRAFFITI_CKEY_UNIQUE_CAP
Most unique arts one account keeps on one map: a tenth of GRAFFITI_MAP_UNIQUE_CAP.
GRAFFITI_COMPOSITE_LINE_GRACE
How long a painter waiting in SSgraffiti's composite line keeps its place without asking again, as one no longer due stops asking. SScustom_sprite_work asks for every waiting painter each tick it gets through its queue.
GRAFFITI_COMPOSITE_SHARE
Of each second, how many ms every painter's composites together may take, freehand sessions' and paint job steps alike. Past it they wait their turn in SSgraffiti's composite line, so with many painters each one's come further apart rather than time dilating. A typical one-tile composite takes 11-15 ms, so about ten painters keep the full spacing. Measured on one build (2026-10-20), it took a hundred freehand painters at the topic limit from 670 to 102 ms/s of composites and +57.2% to +3.0% time dilation, and twenty adversarial ones from +16.0% to +0.8%.
GRAFFITI_DECODE_BUDGET
Most bytes, estimated, of decoded art a map's load keeps at once for its merges and sheets: about 400 dense one-tile arts. Art past it is decoded again where it is needed. Freed memory stays with the process, so this bounds what a load adds to the server's high-water mark.
GRAFFITI_LOAD_SHARE
Percent of each tick the background load of the map's graffiti takes at most (load_yield()), so it spreads over the lobby without the server feeling it: a full map of adversarial art took about 22 s of work, about 90 s at this share.
GRAFFITI_MAP_READ_VERSIONS
The map file versions this server reads. Version 1's anchors may record wall rather than their surface, and its

GRAFFITI_SHEET_STATES
Tile composites packed into one sprite sheet at load: of the packings whose sheet files stay within 256 KiB, the one with the fewest bytes a state, measured on worst-case art: 32 a sheet takes 1,791 bytes a state, largest sheet 113 KB; 64 takes 1,811, largest 225 KB; 128 reaches 448 KB.
