In-game UI reference

arcdps’ developer notes document the EVTC format and the extension API, but say almost nothing about the in-game UI — the options window, the stat columns, and the years of accumulated toggles. arc’s own author put it plainly: “those are the easy parts… it’s all the in-game UI things I’ve added over the years that at this point even I don’t know about.”

This page is a first pass at that gap. It is built by extracting the string literals compiled into the arcdps DLL — labels, tooltips, and internal element ids — not by decompiling or reconstructing source. Everything here is arc describing its own UI, in its own words.

The options window

The DLL’s ImGui element ids expose a tab structure. The following tab grouping is inferred from the tb… id prefixes and needs in-game confirmation:

Inferred tab	Element id(s)
Logging	`tblogging`, `tblogmain`
Windows	`tbwindows`
Interface	`tbinterface`
Extras	`tbextras`
Filter	`tbfilter`
Style (with sub-tabs)	`tbstylestyle`, `tbstylearc`, `tbstylearea`, `tbstylebuffs`, `tbstylegraphs`, `tbstyleprof`, `tbstylesquad`, `tbstylepre`

The content panels arc renders (from area…/…list ids): a stats list (areastatslist), buffs list (areabuffslist), graphs list (areagraphslist), player list (areaplist), plus skill, extension, squad, and subgroup-hide lists (skillslist, extenslist, sqlist, subhidelist) and a log filter/message pane (logfilter, logmessages).

Stat columns and their definitions

The highest-value extraction: arc’s own tooltip text defining what each stat column measures. Quoted verbatim from the DLL.

Contribution & down/kill stats

Column	arc’s tooltip (verbatim)
Contribution damage ratio	“Sum of damage contributions divided by total damage”
Downs damage contribution	(label; see “Damage since 2 seconds before target dropped below full health”)
Downs crowd control contribution	“Crowd control count since 2 seconds before target dropped below full health”
Downs strips contribution	“Strips since 2 seconds before target dropped below full health”
Downs movement slow contribution	“Active movement impairing buff time since 2 seconds before target dropped below full health”
Kills damage contribution	“Damage since 2 seconds before target dropped below full health” (label: Only requires player damage)
Damage while target was down	(label)

The recurring phrase “since 2 seconds before target dropped below full health” is arc’s window for attributing a down — it credits contribution starting 2 s before the target first left full health, not from the down itself. This is the kind of semantic that appears nowhere in the official notes.

Defiance & crowd control

Column	arc’s tooltip (verbatim)
Defiance damage	“Damage to defiance bars only. Excludes loss-of-control effects”
Crowd control count	“Sum of loss-of-control effects. Excludes defiant, defiance bars, and blocked”

Missiles

Column	arc’s tooltip (verbatim)
Missile launch to hit ratio	“(tooltip: skill misses)”
Incoming missile launch to hit ratio	“(tooltip: skill misses)”
Missile effectiveness / Incoming missile effectiveness	(labels)
Missile friendly fire	(label)

Cleave, strips, cleanses, resurrects

Extracted column labels (no tooltip found unless quoted): Outgoing strips on enemies, Outgoing cleanses on allies, strip in / strip out, cleanse in / cleanse out, cleave / cleave bar, Resurrect activations, resurrect count / resurrect time, Times downed, Time between downing, Time spent not dead or down.

Column value modes

Several stats can be displayed in different modes — extracted labels:

As volume: as volume applied, as volume on squad, on subgroup, on friendly, on enemy
As percentage: as percentage of hits, as percentage casting, as percentage polled
Hit filters: hits (all), hits (damage), hits (not-aoe), average all hits
Nominal caps: limit in to nominal (minimum) / (maximum), 1 / 5 / 10 target nominal
Uptime: “Calculate as uptime percentage instead of average”, “Calculate ignoring buff active flag”

Normalized & current-fight stats

arc distinguishes current fight from normalized rolling stats, with these verbatim tooltips:

Current fight: “from first player combat enter to last player combat exit”
Normalized: “accumulated per-player individually, reset as per interface options”
“Minutes. Applies to normalized stats only” (the normalized_rolling_minutes window)
“Seconds. Applies to current fight stats only”
“Seconds. Shared between fight and logging configuration”

Title-bar variables

arc’s stats windows support title-bar format variables. Extracted:

“Variables 1-5 use current fight values only”
“Variables can be found in the checkbox tooltip for each stat”
Column-template strings like @5: squad combat time, @7: combat time for self, @3: cleave percent of total, @6: target percent of total — the @N: variable definitions.
“Stats window ID is displayed in title bar” / “Must use ID lower…”
“Buffs window ID is displayed in title bar”

Window & display options

Extracted toggles (arc’s label text). Behavior unconfirmed:

Visibility: hide windows during combat, …out of combat, …during cinematics, always draw windows, esc closes windows, close window, hide close button in title bar
Interaction: clicking windows requires modifiers, moving windows requires modifiers, slow worldstep when window inactive
Layout: window width, window minimum height, window padding, bar padding, window relative position, from anchor window corner, combine bars across windows
Roster display: Hide player, Hide professions, Hide subgroups, profession icons / profession text, replace player with account name, use unique player colours, use subgroup for bar colour / name colour, use red names for players loading
Privacy: “Hides player names and colours. Disables…” (label Disabled on out-of-party agents)

Build 1.2026.816.1149 (2026-08-26) added five element ids and one tooltip in this area: panelcopy / panelpaste with the tooltip “Paste window configuration” — copying one window’s configuration onto another — and buffsvis / chclivis / squadvis, which by their …vis naming look like per-window visibility controls for the buffs, chat-cli, and squad windows. All unconfirmed in-game, like everything else here; see the build history for the diff.

Logging options

Many logging controls overlap the arcdps.ini keys already documented on the installation & files page and the “why wasn’t my log saved” diagnostics. Extraction adds arc’s own tooltips for a few:

save boss logs / save map logs / save wvw logs, save logs to:
“Must be enabled prior to squad entering combat to log”
“Must be enabled prior to entering instance to log”
“Map ID can be found in the metrics window tooltip. Logging will not…” and “No maps are logged by default, ID can be found in metrics window tooltip.”
“Log all instance maps except those on the map ID list” (the map_encounter_ids_asblacklist toggle)
minimum squad participants / maximum squad participants / percent squad participants / minimum enemy player participants
ignore fights shorter than / ignore logs shorter than, end wvw fight when inactive after

How to help confirm these

Because everything here is unconfirmed, the useful next step is in-game verification: open arc’s options, find the labeled control, and confirm what it does. Confirmed entries can be promoted to [verified] with a note on which tab they live in. The extraction also drops real strings (it filters aggressively to avoid keeping library noise), so the in-game UI is a superset of this list — if you find a control that isn’t here, it’s a genuine addition to document.
