Buffering is enabled by providing multiple texture IDs via `ArSession_setCameraTextureNames(ids)`, or when certain ARCore features like Augmented Images or Faces are active, or on some specific ARCore devices. Frame delay, indicating active buffering, can be monitored via `adb logcat`. Each additional buffered frame increases memory use. Apps can use `ArFrame_getCameraTextureName()` to get the texture ID. The frame rate improvement depends on device and app design.\n"]]
