Stack composer

Started from CZ/SK Bohemia PVP|PVE|MOD|16.10.WIPE: the 32 mods it publishes to the Steam server browser (as of 2026-10-20), put back into load order — servers publish the list last-loaded first. Mods loaded with -servermod= are never published, so they are not here; add them if you know them.

Stall risks

6 in hot hooks

File I/O on hot paths, timers created per event, and per-player-per-frame hooks across the stack. These can stall a frame regardless of the load figure. See all 6 below.

Mods silencing mods

4 conflicts

Across 103 server-side methods hooked by two or more mods. 2 more on client-only UI classes, listed separately.

Structural load

0.16% of a frame at 100 players

1.569 ms per second, all 27 mods combined. Hook dispatch and timers only — not what the hooks do inside. Methodology.

Who silences whom#

A later-loaded mod overrides a method without super(), so the earlier mod's code on that method — and vanilla's — never runs. Whether that is a bug or the whole point of the mod is the author's call; this shows the structure, not intent.

4 methods across 4 pairs. Read across: the mod on the left silences the mod at the top. Both in load order. 1 2–4 5–14 15+ methods

Hot hooks shared across the stack#

The engine calls the last-loaded mod first; each super() hands on to the mod before it, ending at vanilla. Badges show what each mod's override calls inside — that body work, not the chain itself, is what costs frame time.

Stall risks#

6 places where one mod's code can hold up a frame by itself, whatever the load figure says. Each is a pattern found in the code, not a measurement: how much it costs depends on what the hook does inside. Most severe first, then in load order.

Per-player, per-frame hook. Runs for every player on every tick, so whatever it does inside is multiplied by the population.

Admirals Diving Mod

PlayerBase.EOnSimulate

about 30× per player per second
