Crusader Kings 3 is about to get “30-40% bigger,” but Paradox says you can leave performance concerns at the door

With the upcoming expansion of Crusader Kings 3, titled All Under Heaven, players are poised to experience a significant expansion of the game’s map, introducing the vast regions of China, Japan, and Southeast Asia. This development brings with it a plethora of new opportunities for players to explore dynasties, shogunates, and the intricate trade routes of the Silk Road. However, this enlargement of the playable world also raises concerns regarding the potential impact on game performance, particularly in terms of processing speed during gameplay.

Performance Enhancements and Challenges

Paradox, the developer behind Crusader Kings 3, has acknowledged the challenges posed by this expansion. Joel Hansson, the technical lead, noted that the game’s size will increase by approximately 30% to 40%, which translates to a greater number of playable territories and characters. To maintain a seamless gaming experience akin to the current version, the team is focused on optimizing the ‘simulation tick duration.’ This metric determines how swiftly the game processes events in real-time.

Hansson elaborated on the complexities introduced by the new regions, stating, “This expansion presents a larger challenge than any previous one we’ve undertaken for CK3.” The addition of East and Southeast Asia not only leads to a typical slowdown of around 20% due to new features but also introduces a 32% increase in baronies and rulers, which directly correlates with the computational demands placed on the CPU.

Despite these hurdles, recent testing on various hardware configurations indicates that the new build of the game is performing comparably to the existing version. While initial gameplay may experience slight delays, particularly in the early stages, the mid-to-late game shows improved performance metrics.

Optimizing Gameplay Experience

In an effort to enhance performance further, Paradox is also addressing character generation within the game. One popular mod, ‘Population Control,’ has been known to reduce character counts when the world becomes overly populated. While Paradox has not implemented a similar feature, they have worked to minimize the creation of unnecessary characters that clutter the game environment and consume resources. This includes eliminating random or invisible characters that linger in various game pools, thereby streamlining performance.

Hansson cautions that performance outcomes will vary based on individual gameplay experiences and the unique worlds players create. For those interested in the technical intricacies behind these enhancements, a detailed 37-minute video and blog post are available, providing an in-depth look at the development process.

Additionally, Paradox has updated the minimum CPU requirements for the game to ensure optimal performance. The new baseline specifies the Intel i5-750 and AMD FX-4300 with 8GB of RAM, as older CPUs, such as the Intel i3-2120, have shown unpredictable behavior under heavy loads.

The expansion, Crusader Kings 3: All Under Heaven, is set to launch on Tuesday, October 28. Players eager to delve into this new chapter can wishlist the expansion now.
