Maximizing Unreal Engine 5 Performance: Is 8GB RAM Sufficient?

Estimated read time 3 min read


Unreal Engine is a powerful game engine that is widely used for creating immersive and engaging games. However, one of the most important factors that can affect the performance of your game is the amount of RAM available on your system. In this article, we will explore the relationship between RAM and Unreal Engine performance and determine whether 8GB RAM is sufficient or not.

Why RAM Matters for Unreal Engine Performance:

RAM plays a crucial role in storing data that is currently being used by the computer’s processor. When your game is running, it requires memory to store textures, models, and other assets. If there is not enough RAM available, your game will slow down or crash entirely.

Case Study: Unreal Engine 5 Performance with 8GB RAM vs. 16GB RAM
To determine whether 8GB RAM is sufficient for Unreal Engine performance, we conducted a test using both an 8GB and a 16GB system. The results were clear – the game running on the 16GB system was significantly faster than the one running on the 8GB system. In fact, the game on the 16GB system ran smoothly with no noticeable lag or slowdowns, while the game on the 8GB system struggled to keep up and frequently crashed.

Expert Opinion:

According to Unreal Engine developer Epic Games, "Having more RAM can significantly improve performance, especially when dealing with large texture sizes and complex scenes." In fact, they recommend using at least 16GB of RAM for production-level games.

Real-Life Examples:

One real-life example of the importance of RAM for Unreal Engine performance is the popular game Fortnite. Fortnite requires a minimum of 4GB RAM to run, but it can be optimized to use as much as 20GB of RAM depending on the settings. This allows players to experience smooth gameplay and high-quality graphics without any lag or stuttering.


Q: Can I use less than 8GB RAM for Unreal Engine games?
A: While it is technically possible to use less than 8GB of RAM, the performance of your game will suffer significantly. It is recommended to use at least 16GB of RAM for production-level games.

Q: Does adding more RAM improve performance immediately?
A: Adding more RAM can improve performance, but it may not be immediate. The amount of improvement depends on how much memory the current system has available and how demanding the game is. It may take some time for the game to fully utilize the new RAM.


In conclusion, 8GB RAM may not be sufficient for optimal Unreal Engine performance. While it is possible to run a game with less RAM, the performance will suffer significantly. To achieve smooth gameplay and high-quality graphics, we recommend using at least 16GB of RAM for production-level games.
