Core features like Lumen (dynamic global illumination) and Nanite (virtualized geometry) heavily tax the GPU and require high-speed storage read/write operations to prevent severe editor stuttering. Method 1: Building a "Plug-and-Play" Portable Drive
This eliminates the risk of losing work if a physical drive is lost or corrupted, and it provides a complete history of your project. For those new to version control, community tutorials provide simple, visual setups for managing this process.

However, the is not only possible—it is becoming standard.
Official specifications from Epic Games provide a clear starting point. However, the real-world experience on varying hardware can be surprising. A user on the Epic Developer Forums reported running UE5 on a laptop with only 8GB of RAM and a GTX 1050, noting that while "it does work, the experience isn’t really pleasant" due to slow load times. This highlights the difference between simply running the engine and having a smooth, productive development experience.
You can create a "portable" installation of UE5 that runs from an external drive, allowing you to move between different machines without reinstalling the entire 100GB+ engine. I can recommend the exact system specifications or
Until now.
You can bypass the standard installation constraints to work on different computers:
You can spin up a virtual machine equipped with a high-end enterprise GPU (like an NVIDIA A10G) on services like or AWS NV-series instances . You pay an hourly rate to log into a powerful virtual Windows desktop from any web browser or lightweight remote desktop client (like Parsec). Your project files and engine are stored securely in the cloud. 2. Remote Desktop Streaming (Parsec) For those new to version control, community tutorials
Alternatively, you can change this per project by going to inside the editor.
Vault cache files downloaded from the Epic Games Launcher default to the local system drive. To manage assets portably, you must change the "Vault Cache Location" within the Epic Games Launcher application settings to a folder on your external SSD. Best Practices for Mobile Developers
: For the best experience, use an NVMe SSD rather than a standard HDD, as UE5 constantly reads/writes data for shaders and cache. Top Laptops for Unreal Engine 5 (2025-2026)
