# CoH3 Build Studio 3.4.0

## Replay: Player Performance / Commands

- Compare decoded commands across selected players in 30-second, 1-minute, 2-minute or 5-minute intervals.
- Switch between interval counts and cumulative commands. See total commands, average commands per minute, peak minute, abilities and retreats.
- Review movement, attack, attack-move, capture, production, construction, research, upgrades, abilities, retreat, stop, garrison and other/unknown commands.
- Optional team averages and decoded surrender/end markers. Hover for details; click or use the keyboard to select an interval and open that moment in Map & Movement.
- 1v1 selects both players. Team games initially focus on the linked player where their profile can be identified.

These are decoded replay commands, not raw keyboard/mouse APM, confirmed unit completions or a rating of skill. Unsupported records remain unknown. An incomplete final interval is labelled and is not extrapolated into an inflated peak-minute count.

## Multiplayer and OBS overlays

- Country flags beside the nickname in both overlays, with the same public-country normalization.
- Row order: rank insignia → optional leaderboard position → country flag → nickname → optional ELO.
- Independent **Show Country Flags** switches, enabled initially. Your choice persists.
- Missing countries keep a fixed blank slot; late profile loading does not move nicknames. Flags use bundled local assets.
- Existing faction ranks and other overlay settings are retained. Countries are not inferred from names or IP addresses.

## Chat

- Smaller messages, avatars and room-member rows, with more conversation visible at once.
- **In this room** lists people in the room they actually selected. Switching rooms moves your presence; stale activity from another window cannot move it back.
- Leaving chat clears your room presence; after a disconnected or crashed client it expires within approximately two minutes. The roster refreshes every 30 seconds.
- A small sidebar shows the current CoH3 player count on Steam, plus a download-total slot, a thank-you and a Discord feedback link.
- The Steam count includes players running CoH3 on Steam, not just multiplayer or Build Studio users. It is cached for five minutes.
- Download totals require a dated, sourced count supplied by the server operator. Without that source the app says statistics are not connected; it does not display a fabricated total or zero.

New controls and help entries are available in English and Polish.

## Installation

This is a complete Windows installer. Close Build Studio and install over the existing location. Local builds, notes, settings and user media are not reset. Deploy backend 3.4.0 before using room presence and the new counters; instructions are included in the backend package.

The website and public update channel have not been published or changed by this package. Windows execution, a real match and a real OBS recording still require a local acceptance test.
