Mythic Masters walk together: a full party costs about 13 ms a frame (15 rigged walkers), draw far friends cheaper #3704
Description
Measured by the two-page journey (apps/mythic-masters/test/together.test.ts, from #3676) on the office Mac:
| frame time | |
|---|---|
| one friend drawn | 16.5 ms |
| a full party (five friends, each with their two followers: 15 rigged beasts) | 29.9 ms |
Another run under a judge's load measured 36 ms for the full party. So a full party drops the open world from 60 fps to about 30.
Each friend and follower is a Walker3d (src/world/walker3d.ts): a full puppet with its own stand-in fighter, updated every frame in drawFriends (src/world/view.ts).
Likely cheaper, in order:
- Draw a friend's followers only within about 40 m, and as the capsule beyond that.
- Update far friends' puppets every other frame.
- Share skinned meshes between walkers of the same creature.
This overlaps the frame-budget climb, #3664 (Cosmo, src/world/), so it's best taken there or right after it, since both edit the world's frame loop. Done when the two-page journey's full-party line reads under 20 ms on the office Mac, and its assert is tightened to match.

Issue-runner check (2026-11-06): covered by the frame-budget climb #3796, whose target is a party of six (95th percentile under 16.7 ms). Round 5 (#3794) walks with
--party 1,6, profiles it, and runs friends' IK every other frame; #3787 and its follow-up set the party's draw-call limit. Drawing far friends cheaper is that climb's work from here. Phase done; moved up to #3796.QuinnsCode commentedon Nov 9, 2026
