Cities Skylines 2 has faced performance issues and limited content since its launch. Iceflake Studios is working on improvements, collaborating with Unity to address performance challenges. The game is CPU-intensive, with unique challenges due to its dynamic nature. Key areas for enhancement include rendering performance, simulation performance, and pathfinding. Recent changes have simplified citizen modeling and improved pathing, leading to a better gameplay experience. The game's Steam rating has shifted from 'Mixed' to 'Mostly Positive.' Iceflake has developed a benchmarking tool to collect performance data, which will be integrated into an upcoming patch.
