How Much RAM Does Cities Skylines Use



Welcome to the world of Cities Skylines, an immersive city-building simulation game that allows players to design and manage their own virtual metropolises. As you dive into the intricacies of urban development, you may start wondering about the technical requirements needed to run the game smoothly.

One important aspect to consider is the amount of Random Access Memory (RAM) required to ensure optimal performance in Cities Skylines. RAM plays a crucial role in storing and accessing the game’s data, including details of your city, the terrain, and all the assets you have built. Insufficient RAM can result in sluggish gameplay, frequent lagging, or even crashing.

In this article, we will explore the factors that affect the RAM usage in Cities Skylines, recommend the minimum and recommended RAM specifications, and provide tips on how to optimize RAM usage for a seamless gaming experience. Whether you are a casual player or an aspiring city-planner, understanding the RAM requirements of Cities Skylines will help you create and manage your virtual city with ease.


How much RAM is needed to run Cities Skylines?

The amount of RAM needed to effectively run Cities Skylines depends on various factors, including the size and complexity of your city, the number of mods and assets you have installed, and the level of detail and graphics settings you prefer. While the game’s minimum requirements state that 4GB of RAM is sufficient, it is recommended to have at least 8GB of RAM for a smooth and enjoyable gaming experience.

For small to medium-sized cities with a limited number of mods and assets, 8GB of RAM should be adequate. However, if you have a larger city with an extensive collection of mods and assets, or if you enjoy playing with high-definition textures and advanced graphics settings, you may want to consider upgrading to 16GB or even 32GB of RAM for optimal performance.

Keep in mind that Cities Skylines is a memory-intensive game, especially when it comes to rendering detailed landscapes, simulating traffic, and managing a complex network of entities. The game also relies heavily on the CPU, so having sufficient RAM is crucial to ensure a smooth gameplay experience, with minimal lag and reduced loading times.

Furthermore, if you plan to use various mods and assets from the ever-growing Steam Workshop community, it is wise to allocate additional RAM to accommodate their requirements. Some mods may add new buildings, vehicles, or other elements that increase the RAM usage of the game.

It’s worth mentioning that having ample RAM not only improves the performance of Cities Skylines but also allows for multitasking while playing the game. If you like to have multiple applications running in the background, such as web browsers, music players, or video editing software, it is recommended to have a higher RAM capacity to ensure smooth gameplay and seamless multitasking.

In the next section, we will explore the factors that influence RAM usage in Cities Skylines, shedding light on the specific elements that consume memory and providing further insights into optimizing your RAM usage for an enhanced gaming experience.


Factors that affect the RAM usage in Cities Skylines

Several factors contribute to the amount of RAM that Cities Skylines utilizes during gameplay. Understanding these factors will help you optimize your RAM usage and ensure smooth performance. Here are some key factors to consider:

City Size and Complexity: The size and complexity of your city have a significant impact on RAM usage. As your city grows with more buildings, infrastructure, and population, the game needs to store and process a larger amount of data. Larger cities require more RAM to handle the increased demands of simulation and rendering.

Mods and Assets: The use of mods and assets can greatly enhance your Cities Skylines experience, but they also contribute to increased RAM usage. Each mod or asset you install adds additional data that the game needs to load and manage. The more mods and assets you have, the more RAM the game will require to support their functionality.

Graphics Settings: The graphical settings you choose can impact RAM usage as well. Higher resolutions, anti-aliasing, advanced lighting effects, and other graphic-intensive settings can increase the demand for memory. If you have limited RAM, lowering these settings may help improve performance.

Simulated Entities: Cities Skylines simulates a variety of entities, including citizens, vehicles, and industry processes. The more entities in your city, the more RAM is required to keep track of their behavior and interactions. Factors such as traffic density, public transportation usage, and city events can affect the number of simulated entities and consequently impact RAM usage.

Plugins and DLCs: Additional plugins and DLCs (Downloadable Content) may introduce new features, mechanics, or assets to the game. These additions can increase the overall RAM usage as well. Make sure to consider the RAM requirements of any plugins or DLCs you install.

Operating System and Background Processes: The operating system and other background processes also consume a portion of your system’s RAM. If you have numerous applications running simultaneously, they will compete with Cities Skylines for available memory. To optimize RAM usage, consider closing unnecessary background processes before launching the game.

Understanding these factors and their impact on RAM usage will help you make informed decisions when it comes to optimizing your game settings and upgrading your hardware if necessary. In the next section, we will provide recommended RAM specifications for Cities Skylines and share tips on how to optimize your RAM usage for a smooth gaming experience.


Recommended RAM specifications for Cities Skylines

To ensure an optimal gaming experience in Cities Skylines, it is recommended to have a certain amount of RAM based on the size and complexity of your city, the use of mods and assets, and your desired graphics settings. Here are the recommended RAM specifications for different scenarios:

Minimum Requirements: The minimum requirement for Cities Skylines is 4GB of RAM. While the game can technically run on this amount of memory, it may result in subpar performance, especially for larger cities and with the use of mods or high-definition textures. It is advisable to have more than the minimum requirement for a smoother gameplay experience.

Small to Medium-sized Cities: For small to medium-sized cities with a moderate number of mods and assets, 8GB of RAM is recommended. This amount of memory should be sufficient to handle the simulation, rendering, and mod functionality without significant issues. It provides an adequate buffer for expansion as your city grows.

Large and Complex Cities: If you plan to build extensive and highly-detailed cities with a multitude of mods, assets, and advanced graphics settings, it is advisable to have 16GB or even 32GB of RAM. These higher RAM capacities will provide a smoother gaming experience, preventing slowdowns, lag, and crashes caused by insufficient memory.

Future-proofing and Multitasking: If you want to future-proof your gaming setup or engage in multitasking while playing Cities Skylines, consider opting for a higher RAM capacity. With 16GB or more, you can comfortably run the game while having multiple applications running simultaneously, such as web browsers, music players, or design software.

Remember that these recommended RAM specifications can vary depending on your individual preferences, gameplay style, and other hardware specifications. It is also essential to keep your operating system and graphics card drivers up to date for optimal performance.
