System requirements


Azure Remote Rendering is currently in public preview. This preview version is provided without a service level agreement, and it's not recommended for production workloads. Certain features might not be supported or might have constrained capabilities. For more information, see Supplemental Terms of Use for Microsoft Azure Previews.

This chapter lists the minimum system requirements to work with Azure Remote Rendering (ARR).

Development PC

  • Windows 10 version 1903 or higher.
  • Up-to-date graphics drivers.
  • Optional: H265 hardware video decoder, if you want to use local preview of remotely rendered content (for example in Unity).


Windows update doesn't always deliver the very latest GPU drivers, check your GPU manufacturer's website for latest drivers:

The table below lists which GPUs support H265 hardware video decoding.

GPU manufacturer Supported models
NVIDIA Check the NVDEC Support Matrix at the bottom of this page. Your GPU needs a YES in the H.265 4:2:0 8-bit column.
AMD GPUs with at least version 6 of AMD's Unified Video Decoder.
Intel Skylake and newer CPUs

Even though the correct H265 codec might be installed, security properties on the codec DLLs may cause codec initialization failures. The troubleshooting guide describes steps how to solve this problem. The DLL issue can only occur when using the service in a desktop application, for instance in Unity.


Azure Remote Rendering currently only supports HoloLens 2 and Windows desktop as a target device. See the platform limitations section.

It's important to use the latest HEVC codec, as newer versions have significant improvements in latency. To check which version is installed on your device:

  1. Start the Microsoft Store.
  2. Click the "..." button in the top right.
  3. Select Downloads and Updates.
  4. Search the list for HEVC Video Extensions from Device Manufacturer. If this item is not listed under updates, the most recent version is already installed.
  5. Make sure the listed codec has at least version 1.0.21821.0.
  6. Click the Get Updates button and wait for it to install.


A stable, low-latency network connection is critical for a good user experience.

See dedicated chapter for network requirements.

For troubleshooting network issues, refer to the Troubleshooting Guide.

Network firewall

SDK version >= 0.1.76

Remote Rendering virtual machines use shared IP addresses from the following IP ranges:

Name Region IP prefix
Australia East australiaeast
East US eastus
East US 2 eastus2
Japan East japaneast
North Europe northeurope
South Central US southcentralus
Southeast Asia southeastasia
UK South uksouth
West Europe westeurope
West US 2 westus2

Make sure that your firewalls (on device, inside routers, etc.) don't block these IP ranges and the following port ranges:

Port Protocol Allow
49152-65534 TCP / UDP Outgoing

SDK version < 0.1.76

Make sure that your firewalls (on device, inside routers, etc.) don't block the following ports:

Port Protocol Allow Description
50051 TCP Outgoing Initial connection (HTTP handshake)
8266 UDP Outgoing Data transfer
5000, 5433, 8443 TCP Outgoing Required for ArrInspector tool


The following software must be installed:

  • The latest version of Visual Studio 2019 (download)
  • Visual Studio tools for Mixed Reality. Specifically, the following Workload installations are mandatory:
    • Desktop development with C++
    • Universal Windows Platform (UWP) development
  • Windows SDK 10.0.18362.0 (download)
  • GIT (download)
  • Optional: To view the video stream from the server on a desktop PC, you need the HEVC Video Extensions (Microsoft Store link). Ensure that the latest version is installed by checking for updates in the store.


For development with Unity, install

  • Unity 2019.3.1 (download)
  • Install these modules in Unity:
    • UWP - Universal Windows Platform Build Support
    • IL2CPP - Windows Build Support (IL2CPP)
