Per OpenXR's COMPOSITION LAYER spec, UI elements rendered as a quad layer (vs blended into the eye-buffer) gain which property?
ASampled at native panel resolution each frame
BAlways smaller GPU memory footprint
CMandatory 3D audio attachment for accessibility
DFaster CPU dispatch always for layer init
Answer & Solution
Correct answer: A. Sampled at native panel resolution each frame
OpenXR Spec composition layers: the runtime composites the layer directly to the display. Avoids the double-resampling of eye-buffer rendering — crisp text.
