Configuration
2x32GB dual-channel
Stutter & Frame drops: Cities 2 utilizes a highly complex Entity Component System (ECS) to simulate millions of individual pathfinding agents (Cims). When your city grows past 100k population, system memory paging limits are reached, resulting in severe simulation slowdown and slow UI response times.
CC & Modding Impact: Installing custom asset modpacks and script mods via Paradox Mods increases the baseline memory heap, requiring 64GB of RAM to prevent pagefile thrashing on large cities.
Below are realistic Event Viewer error reports and game logs that trigger when Cities: Skylines II runs out of memory or hits single-channel bottlenecks.
[SYSTEM] Pathfinding thread: active agent count exceeds 150,000 entities
[WARNING] System Virtual Memory paging bounds reached; swapping active virtual pages to disk
[ERROR] Simulation speed severely limited by Memory Controller thread queuing bounds
[HELP] To resolve, upgrade to a sweet-spot dual-channel configuration (DDR5-6000 CL30 or DDR4-3200 CL16).
