CitiesAI 0.9.3

Fixes

• Fixed a critical crash when quitting from the system tray.
• Concrete UI fixes.

Install

1. Close Cities: Skylines II completely.
2. Download CitiesAI-Setup-0.9.3.exe below.
3. Start CitiesAI, then load a city in CS2.

CitiesAI 0.9.2

Highlights

• Co-Mayor is quieter and more useful: one grade, one issue line, Ask on click, and it hides when you alt+tab.
• Fairer report card — recalculated everything to be graded much better.
• Faster dashboard and Co-Mayor polls, plus an export mod that counts the city exactly by default.
• Setup now installs the CS2 Data Export mod into your game Mods folder (close CS2 first).
• Clearer freshness and confidence so you can tell live data from aging snapshots.

Co-Mayor

• Compact strip shows grade + one center line
• Click the issue line to open Ask with that issue’s prompt.

Clearer, fairer advice

• Graded export freshness (live / aging / stale).
• Fairer domain scoring; example: strong residential demand is treated as growth, not failure.
• Evidence coverage strip; official-stats fallback badge.

Faster and lighter

• Faster dashboard / Co-Mayor / history paths on the app side.
• Export mod: exact population / household / workplace counts by default; export loop re-arms after leaving a city / loading a save.

Transit

• Better line naming in Line Doctor; one aggregate Transit coverage gaps issue.

Install

1. Close Cities: Skylines II completely.
2. Download CitiesAI-Setup-0.9.2.exe below — it installs CitiesAI and copies the export mod into Mods\CS2DataExport.
3. Start CitiesAI, then load a city in CS2 and wait ~10 seconds for the first snapshot.

CitiesAI 0.9.1

Performance

• CitiesAI app — fewer duplicate snapshot parses, historian loads, and wiki searches on dashboard / Co-Mayor / Ask hot paths.

Reliability

• Corrupt or non-object exports and JSON bodies rejected instead of looking healthy; unauthenticated GET key-test removed.

Estimated impact

• Roughly ~60–80% less redundant work on top of late 0.9.0’s performance optimizations.

Install

Download CitiesAI-Setup-0.9.1.exe below. Close CS2 before installing so the bundled export mod can update.

CitiesAI 0.9.0

Ask

• Improved harness.

Performance

• CS2 Data Export — further CPU and hitch reductions. Quieter export/observer duty cycle and tighter hot paths.
• CitiesAI app — lighter dashboard / Co-Mayor poll paths

Estimated Impact

• Roughly 50–70% less CPU usage on top of 0.7.4 release, which was the first major performance optimization patch.

Install

CitiesAI 0.7.4

Performance

• CS2 Data Export — major FPS improvements:
  • Transit access-gap observer no longer scans every PathOwner entity every frame; citizens-only query, 6-frame throttle (configurable), cached entity queries, and stop-list refresh only when stop count changes.
  • Export cycle memoization deduplicates population/workforce scans (7× → 1×), workplace scans (5× → 1×), household economy/pressure passes (2× → 1×), and GetSortedLines (2× → 1×) per 5s snapshot.
  • Snapshot retention runs every 10th export instead of every export; optional CS2DATAEXPORT_PROFILE=1 logs per-phase timings to CS2DataExport.log.

Fixes

• Dashboard — when CS2 Data Export official city statistics fail, fill treasury/income/health/wellbeing/crime from recent historian snapshots instead of showing n/a.
• CS2 Data Export (vendor) — harden official city statistics probe against runtime NullReferenceException.
• Doctor — warn when official city statistics export is degraded.

Estimated Impact

• ~75–85% less mod CPU usage during gameplay (sustained observer cost down ~90%+; export spikes down ~50–60%).
• Workaround env vars: CS2DATAEXPORT_TRANSIT_CAPTURE=off, CS2DATAEXPORT_TRANSIT_OBSERVE_EVERY_N_FRAMES, CS2DATAEXPORT_TRANSIT_CAPTURE_COOLDOWN_MINUTES.

Install
