Iray Programmer's Manual

System requirements

The current system requirements for Iray Interactive:

  • The plugin libirt needs to be loaded in neuray before this render mode is available. See the mi::neuraylib::IPlugin_configuration interface for methods to load plugins.

  • Available on Windows x86 64 bit, Linux 64 bit, and Mac OS X 64 bit.

  • GPUs of the Fermi and Kepler generations are supported by Iray Interactive, i.e., with CUDA Compute Capability 2.0 and higher. The following device configurations are supported:

    • Arbitrary combinations of Compute Capability 2.x devices

    • Compute Capability 3.0 devices only

    • Compute Capability 3.5 devices only


    The following device configurations are not supported:

    • Mixing Fermi- and Kepler-based devices
    • Combining Compute Capability 3.0 and Compute Capability 3.5 devices
    • Switching at runtime between different GPU generations, for example, switching from a Compute Capability 3.0 to a Compute Capability 2.0 device.
  • Driver requirements: The driver needs to support CUDA 6.0.
