Performance & Optimization
The movement animations of the NPCs have been optimized. NPCs that are not visible are no longer animated, which significantly reduces the load on the GPU. The shadow casting of the NPCs has been optimized to save on performance.
Furthermore, following the same principle as in the last patch, textures have been optimized and their size reduced (without visible loss of quality) in order to optimize RAM usage. Optimizing the shadow casting of small decorative objects resulted in a noticeable performance gain.
The LODs of numerous buildings have been optimized. As a result, RAM usage decreases and the GPU is relieved.
All of these optimization measures become noticeable when building medium and larger cities (between 10% and 30% depending on the map).
Balancing
Adjustments to building maintenance costs

Difficulty easy: 60% less consumption
Difficulty normal: 60% less consumption
Difficulty hard: 40% less consumption
Buildings

An empty building decoration tile (1x1) has been added to the harbor so that the harbor area can be visually enhanced.
Some residential buildings at the "simple house" level were positioned incorrectly when zoomed out.
Bug Fixes

People on the marketplace and the forum sometimes could not find their way and stopped moving.
Carts no longer continue moving while in pause mode.
When building a clay mine, unavailable resources were displayed incorrectly.
The supply calculation of the wells was calculated correctly when upgrading a personal slave or freedman, but was not displayed correctly visually.
The supply range of the popina was calculated and displayed incorrectly by 1 tile.
If you built an aqueduct and immediately started with a curve, the aqueduct did not work on certain maps.
Due to a rounding error in the calculation, the Castellum Divisorium randomly failed to work in certain weeks and then worked again.
Text elements were missing next to the forum radius in the career view.
The bridge monument sometimes could not be built, appeared rotated 90 degrees the wrong way, or did not appear after saving.
The corruption value of your own slaves was displayed but was not factored into the calculation. This led to situations where, under certain circumstances, neither an increase nor a reduction in corruption had any effect. Additionally, this influence was not shown in the corruption overview in the main menu.
The large city gate was incorrectly displayed as a protected building.
When restarting a city, the supply ship did not carry any resources. This led to a game over, particularly in story mode, since you could no longer build a new city.
Fixed keyboard mapping issues in the AZERTY layout.

🏛️ Pax Augusta – Important Update: Performance, QoL & Security
Balancing / Gameplay Changes & Quality of Life Updates
This update delivers important performance, stability, and quality-of-life improvements across multiple areas of Pax Augusta.
Players should notice smoother performance, reduced GPU/RAM usage, and improved stability.
⚙️ Performance & Optimization
Reduced unnecessarily large textures – saving between 300 MB and 1 GB of RAM, depending on the map, with no visible loss of quality.
Optimized Ambient Occlusion code, reducing draw calls by up to 30%.
Various GPU optimizations across multiple structures:
Street tiles
Forum square tiles
City walls
Wells
Level 1 buildings and GapFiller (Level 1)
Level 2 buildings and GapFiller (Level 2)
Horrea buildings
Fisherhouse
Farm
Improved several NPCs to reduce CPU usage.
🔊 Audio Fixes
Fixed several structures producing strange noises even when sounds were turned off:
Gladiator School
Medium Bathhouse
Small Mill (GapFiller)
Small Bathroom
🐞 Bugs & Security
Integrated latest Unity security update (Unity Security Fix – Sept 2025-01) to ensure engine-level stability and player data protection.
🧩 Developer’s Note
This is an important milestone in our ongoing work to optimize performance and improve stability.
We are continuing to refine the engine and assets, but the process is more complex than initially expected, as it involves extensive texture reworks and deep-level performance adjustments.
We appreciate your patience and ongoing support as we continue to make Pax Augusta smoother, faster, and more stable with each update.

There is a known error when building a bridge monument. This will be fixed with the next patch. All other known bugs will also be addressed in the coming days.
Balancing/Gameplay Changes / QoL

New icon for full screen mode (Settings/Graphics), icon also available on the home screen.
Buttons in the settings renamed from „close“ to „save“.
Built-in autosave function. Set to 15 minutes by default. Can be adjusted in the settings menu.
Adjusted the loading behavior for a saved city. It now shows how many buildings still need to be loaded until the savegame is fully loaded. Previously, the map was simply blank, and you didn’t know if something was still loading or if the savegame had an error.
If you already have a contract with a merchant on the world map, the merchant’s marker will no longer be displayed. Therefore, you will only see the merchants with whom you don’t have a contract.
Bugs

An upgrade to the theater/arena/odeon resulted in some food being lost per week: fixed.
The Spanish translation has some major problems, as incorrect texts lead to incorrect messages: fixed.
Some Spanish texts appear in the wrong position: fixed.
German text correction: fixed.
French text correction: fixed.
Production buildings show 0 production even though they are functioning: fixed.
Missing regional marble quarry in beginner map added.
The stone arena provides no entertainment points: fixed.
Blue T-pose guy – missing animation added.
Game saves weren’t saved correctly when leaving the city. The city was no longer there when loading. This issue is caused by two bugs. One is related to the actual saving process. This has been fixed. The other bug is still pending.
Wrong text when upgrading the iron production engine house: fixed.
Sometimes the mouse pointer does not respond when you click on the marker to build a bridge monument: fixed.
The Gladiator School could not be unlocked in some cases: fixed.
RAM consumption when starting a new city reduced by ~65%.
Certain carts had a malfunction in the path calculation, which resulted in the carts not appearing at the edge of the map or leading to crashes: fixed.
Dirt elements on city streets were always visible rather than appearing randomly: fixed.
Incorrect size display of backyard building A at Cives. Instead of 3×2, it was 4×2.
If you receive an emergency brick delivery in the easiest mode, the message appears every 5 seconds. Bug fixed. You no longer have to search for the bricks; they are added directly to your inventory.
If you built a necropolis on the edge of map 10, it could cause various game mechanics to no longer work.
If you applied for a rank and quit the game instead of going to collect the certificate, it was no longer possible to collect the certificate after a restart: fixed.
It was not possible to apply for the rank of consul: fixed.
Contracts concluded with a merchant on the world map were not saved under certain circumstances. The contracts were invalid upon loading: fixed.
If you bought food from a merchant on the world map, it didn’t arrive: fixed.
Setting a festival calendar would result in a lot of personal money being lost on a regular basis. This issue has been resolved.
It was not possible to demolish a Lupanar during the construction process: fixed.
If you want to demolish a building during construction, the new construction site elements (placeholders) do not disappear.
The white harbor building could be built without Vitruvius having already discovered the harbor.
In large cities, too many noise sources (e.g. from animals) have led to performance losses.
Story (and Story-Related Bugs)

If you go to Britain with the car and save in between, you can no longer continue playing the game.
In story mode, after visiting Rome, some players had a background image with a street and houses on the side that wouldn’t disappear. I couldn’t reproduce the bug. I found a solution to why the image wouldn’t disappear. It will be interesting to see if players continue to report this issue or if it has been resolved.
