Unreal XR and Unity's XR pipeline both offer motion smoothing techniques to enhance the visual experience in VR by reducing perceived motion blur and maintaining frame rates. However, they implement these techniques differently due to their distinct rendering architectures and engine capabilities. Unreal XR typically leverages its Temporal Anti-Aliasing (TAA) and Motion Vector fields to achieve smoother motion, while Unity XR uses Adaptive Performance and Motion Vector support within its Universal Render Pipeline (URP) or High Definition Render Pipeline (HDRP).
