The short version

  • Each has a real cost: Unity AR Foundation requires platform-specific plugins (ARCore, ARKit) to actually implement AR features; Unreal Engine VR steep system requirements with demanding GPU and CPU for rendering high-quality VR experiences
  • They diverge on capability: Unity AR Foundation covers Plane detection, Unreal Engine VR covers Photorealistic rendering.

Where each one falls short

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

Unity AR Foundation

  • Requires platform-specific plugins (ARCore, ARKit) to actually implement AR features
  • Performance varies significantly by device, with battery drain and heat generation on mobile
  • Emulators cannot accurately test AR experiences due to missing camera and sensor data
  • No WebXR support for browser-based AR experiences
  • Occlusion features show lower performance at 25-40 FPS compared to other features at 40-60 FPS
  • Limited access to latest platform-specific features compared to native ARKit or ARCore

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
