CityEngine runs on all three major operating systems.
Native 64-bit and 32-bit versions are available for Windows (7/Vista/XP).
A native 64-bit version is available for Linux and Mac OS X with Intel processors (no CityEngine support for 32-bit or PowerPC Macs).
CityEngine requires approximately 1 GB free memory for startup. Additionally, a small 3D scene with a few hundred low-resolution buildings requires 0.5 to 1 GB RAM (depending on the graphics card memory). In case your operating system uses another 1 GB RAM, you would therefore need at least 2 to 3 GB.
Therefore, we recommend you use a 64-bit operating system with 6 GB RAM. With such a system, you can work with larger 3D scenes and have other applications running in the background without problems.
Yes, CityEngine is a native 64-bit application.
Therefore, if needed, CityEngine could make use of all your memory (and not just 2 to 3 GB, as in 32-bit applications).
CityEngine runs on all major Linux distributions as long as the following requirements are fulfilled:
Please make sure your graphics card is OpenGL 2.x capable and the drivers are also up-to-date to run the OpenGL 2.x standard. If your graphics card is not capable of OpenGL 2.x, you will need to buy a new graphics card to run CityEngine.
OpenGL drivers are usually installed together with the rest of the graphics driver and support software (such as DirectX). Therefore, download the latest drivers from NVIDIA, ATI/AMD, or Intel for your specific graphics card on the manufacturer's homepage. Most often, it is downloadable as an installer file.
No, CityEngine needs physical hardware, since the graphics card’s OpenGL rendering cannot be emulated.
