Ue4 Prerequisites X64 Jun 2026
Technical Specifications & Prerequisites: Unreal Engine 4 (x64) Document Version: 1.0 Target Platform: Windows x64, Linux x64 Engine Version: UE4.27+ (Latest Mainstream Build) 1. Executive Summary Unreal Engine 4 is a native 64-bit application suite. As of UE4.22, Microsoft has deprecated official support for 32-bit builds. This document outlines the mandatory hardware, operating system, software dependencies, and BIOS/UEFI configurations required to compile, run, and deploy UE4-based projects on the x86-64 (x64) architecture. 2. Operating System & x64 Specifics To utilize the full addressable memory space (>4GB) required for PIE (Play In Editor) and lighting builds, an x64 OS is mandatory. | Operating System | Minimum Version | x64 Requirement | | :--- | :--- | :--- | | Windows | Windows 10 (Version 20H2) | 64-bit CPU with SLAT (Second Level Address Translation) | | Linux | Ubuntu 22.04 LTS (Focal Fossa) | Clang 15+ for x86_64-linux-gnu | | macOS | Monterey (12.0) | Apple Silicon (ARM64) or Intel x64 (via Rosetta 2 for tools) |
Note: The Editor is not supported on Windows 7 or 8.1 x64 for UE4.27+.
3. Hardware Prerequisites (x64 Architecture) 3.1 CPU Requirements UE4 leverages AVX (Advanced Vector Extensions) instructions for physics and rendering.
Minimum: x64 CPU with 4 cores / 8 threads (e.g., Intel Core i5-7500, AMD Ryzen 5 1400). Recommended: 6 cores / 12 threads (e.g., Intel i7-10700K, AMD Ryzen 7 5800X). Critical Feature: AVX2 support (required for Nanite/Virtual shadow maps in UE4.27+). ue4 prerequisites x64
3.2 Memory (RAM) - The x64 Advantage x64 addressing allows UE4 to exceed the legacy 4GB limit.
Minimum: 8 GB RAM (Light blueprint only; shader compilation will thrash ). Recommended: 32 GB RAM (Standard for medium open-world maps). High-End: 64 GB+ (For large streaming levels + simultaneous Shader Compilation Workers).
3.3 GPU Requirements DirectX 12 (Feature Level 11_0) or Vulkan is required. | Operating System | Minimum Version | x64
Minimum: NVIDIA GTX 1060 6GB or AMD Radeon RX 580 8GB. x64 Driver Note: Requires 64-bit WDDM 2.0+ drivers. VRAM: 4GB absolute minimum; 8GB+ for open-world projects.
4. Software Prerequisites (x64 Toolchains) 4.1 Windows x64 Development Environment | Component | Version | Architecture | Purpose | | :--- | :--- | :--- | :--- | | Visual Studio | 2022 (v143) | x64 | C++ Compiler, IDE | | Windows SDK | 10.0.19041.0+ | x64 | Windows headers/libraries | | .NET Framework | 4.8 | Any CPU | AutomationTool, UnrealBuildTool | | UnrealVS Extension | Latest | x64 | VS integration for build targets | VS Workloads required:
"Game development with C++" "Unreal Engine installer" (Optional but recommended) Individual Component: MSVC v143 - VS 2022 C++ x64/x86 Spectre-mitigated libs Game development with C++"
4.2 Linux x64 Prerequisites # Install x64 specific toolchains sudo apt install clang-15 lld-15 sudo apt install build-essential libx11-dev libxcursor-dev libxrandr-dev # Mono for UnrealBuildTool (x64) sudo apt install mono-complete
