+Changed
+^^^^^^^
+
+* Enabled synchronous texture streaming on the internal OVRTX ``RendererConfig`` in
+  :class:`~isaaclab_ov.renderers.ovrtx_renderer.OVRTXRenderer` via
+  ``texture_streaming_mode=TextureStreamingMode.SYNCHRONOUS`` to improve cross-run
+  render determinism. Requires ``ovrtx>=0.4.1``.
