A native 64-bit version of CityEngine is available for Windows (8.1/8/7), Mac OS X (10.8/10.7).
CityEngine is not supported on 32-bit Windows operating systems 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, a minimum of 2-3 GB of RAM is required.
*A 64-bit operating system with 6 GB RAM is recommended. This would allow work with larger 3D scenes while running other applications in the background without difficulty.
CityEngine is a native 64-bit application and if needed, CityEngine can make use of all available system memory.
Make sure your graphics card is OpenGL 2.x minimum capable and that your drivers are up-to-date to run the OpenGL 2.x standard. If your graphics card is not OpenGL 2.x capable, you will need to buy a new graphics card to run CityEngine.
OpenGL drivers are usually installed together with the rest of the graphics drivers and support software (such as DirectX), but may be out of date. It is highly recommended to download the latest drivers from NVIDIA, AMD/ATI, or Intel. Your specific graphics card's latest drivers may be found on the manufacturer's home page.
Yes. The environment must be adequately configured with GPUs designed for virtualized environments.
