Hardware requirements

The following table lists the hardware requirements for CityEngine 2022.1:

Requirement	Minimal	Recommended
CPU	Intel/AMD compatible (x86_64) quad-core	Intel i5 (10th Gen) 8-core or AMD Ryzen 5 (3rd Gen) 8-core or higher
Memory	16 GB	32 GB or more
Disk Space	4 GB	32 GB or more
GPU ^1	Intel ^2 HD Graphics 500 Series Nvidia Geforce GTX 950 or Quadro M2000 AMD RX 500 Series	Nvidia GTX 1080, Quadro P5000 or newer AMD RX 5700 XT or newer
GPU Memory	2 GB	8 GB or more
OpenGL	4.1	Latest
Screen Resolution	1280x720	1920x1200 (or higher)
Network	Internet connection	100 Mbps (or higher) internet connection

• 1. It is recommended that you use the latest GPU drivers.
• 2. Intel integrated GPUs are only supported on Windows.

Software requirements

The following table lists the software requirements for CityEngine 2022.1:

Operating system	Software
Windows	Unreal exporter—To enable Unreal exporter, install the Epic Games Launcher from www.unrealengine.com.
Red Hat Enterprise Linux (RHEL)	Install the Server with GUI group. Add the redhat-lsb package.

Virtualization

CityEngine uses the OpenGL graphics API to render city scenes in its viewports. Software-based virtualized GPUs do not offer the performance required for CityEngine. Desktop virtualization products such as VMware Workstation and VirtualBox are not supported.

Enterprise-grade and cloud-based virtualization solutions offer the option to virtualize the GPU (Nvidia vGPU, AMD MxGPU). Alternatively, a dedicated GPU can be passed through, which means the entire graphics card is provided for use by the virtual machine. A virtual machine provisioned with either a virtualized GPU or a dedicated (pass-through) GPU provides the necessary graphics performance for CityEngine.

You can install and run CityEngine on cloud-based environments. However, due to the large number of virtual machine and operating system combinations available, Esri does not offer technical support or troubleshooting for these configurations. If you encounter issues when running CityEngine in cloud-based virtual machines, consult the documentation from your cloud provider.

See the Hardware requirements section above for more information.

The following table lists the virtualization requirements for CityEngine 2022.1:

On-premises virtual desktop infrastructure (VDI)	Notes
VMware vSphere	Nvidia vGPU enabled virtual machines
GPU	Minimum: Nvidia M-Series AMD FirePro S7150 Recommended: Nvidia RTX 6000 or later
Virtual disk size ^3, 4	Minimum: 65 GB Recommended: 90 GB or more
Virtual GPU memory ^5	Minimum: 2 GB Recommended: 8 GB or more

• 3. Disk size includes space for the base OS installation plus space for CityEngine projects, examples, and tutorials.
• 4. Importing and exporting different file formats in CityEngine can be computer intensive. It is recommended that you use an SSD-based direct-attached storage system if your workflow includes frequent import and export steps.
• 5. Refer to the GPU vendor's documentation on how to partition the graphics card.

Note:

It is expected that the VDI solutions of other vendors (Microsoft Hyper-V, Citrix XenDesktop, for example) provide a similar experience. However, Esri does not offer support or troubleshooting when running CityEngine in these environments. Consult with the manufacturer if you encounter issues.

Limitations

The following are known limitations:

• CityEngine does not support all roaming profile features.
• NTLM proxies are not supported.
