Specialised real-time graphics software that generates stereoscopic imagery for virtual reality headsets, optimising frame rates (minimum 90 fps), motion-to-photon latency (sub-20 ms), and visual fidelity while managing VR-specific pipeline requirements including foveated rendering, asynchronous reprojection, and lens distortion correction. Leading implementations include Unreal Engine 5 (Lumen, Nanite) and Unity (URP/HDRP), both supporting major XR hardware via OpenXR and platform-specific SDKs.

Overview
- VR rendering engines power immersive experiences by generating real-time stereoscopic graphics at 90Hz or higher refresh rates. Unreal Engine 5 leads with photorealistic rendering through Lumen and Nanite technologies, while Unity dominates the Meta Quest platform with approximately 70% of games. Both engines support major VR hardware including Oculus, HTC Vive, Valve Index, and PlayStation VR.
