  In the digital era, Extended Reality (XR) is considered the next frontier.
However, XR systems are computationally intensive, and they must be implemented
within strict latency constraints. Thus, XR devices with finite computing
resources are limited in terms of quality of experience (QoE) they can offer,
particularly in cases of big 3D data. This problem can be effectively addressed
by offloading the highly intensive rendering tasks to a remote server.
Therefore, we proposed a remote rendering enabled XR system that presents the
3D city model of New York City on the Microsoft HoloLens. Experimental results
indicate that remote rendering outperforms local rendering for the New York
City model with significant improvement in average QoE by at least 21%.
Additionally, we clarified the network traffic pattern in the proposed XR
system developed under the OpenXR standard.
