The short version

  • Each has a real cost: O3DE minimum hardware is a quad-core 2.5 GHz x86 CPU with SSE 4.1, 16 GB RAM and a DirectX 12 or Vulkan GPU with 2 GB VRAM and Shader Model 6.2; Unreal Engine VR steep system requirements with demanding GPU and CPU for rendering high-quality VR experiences
  • They diverge on capability: O3DE covers 3D graphics rendering, Unreal Engine VR covers Photorealistic rendering.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

O3DE

  • Minimum hardware is a quad-core 2.5 GHz x86 CPU with SSE 4.1, 16 GB RAM and a DirectX 12 or Vulkan GPU with 2 GB VRAM and Shader Model 6.2
  • Raytracing features require Shader Model 6.3
  • Disk space required is 40 GB using the prebuilt installer and 100 GB or more when building from source
  • Building the engine from source needs 2 GB of RAM per build thread on top of normal system requirements
  • On Windows the editor requires Windows 10 version 20H2 or later plus Visual Studio 2019 16.11.x, 2022 17.3.x or 2026 18.0.x with the Game development with C++ workload
  • The only primary Linux distribution for the editor is Ubuntu 22.04 LTS, and Ubuntu on 64-bit ARMv8 is experimental
  • Linux builds need CMake 3.30.0 or later, which is newer than the 3.22 shipped by default with Ubuntu 22.04
  • Wayland support is experimental, requires building from source, and is limited to the Game Launcher with no editor support until O3DE moves to Qt6
  • Linux requires a long list of additional apt library packages to be installed before building

Unreal Engine VR

  • Steep system requirements with demanding GPU and CPU for rendering high-quality VR experiences
  • Only free with 5% royalty after $1 million in revenue, which may impact indie developers at scale
