System Requirements

For development

OS: Windows 7 SP1+, 8, 10, 64-bit versions only; macOS 10.12+. (Server versions of Windows & OS X are not tested.)

CPU: SSE2 instruction set support.

GPU: Graphics card with DX10 (shader model 4.0) capabilities.

The rest mostly depends on the complexity of your projects.

Additional platform development requirements:
  • iOS: Mac computer running minimum macOS 10.12.6 and Xcode 9.4 or higher.

  • Android: Android SDK and Java Development Kit (JDK); IL2CPP scripting backend requires Android NDK.

  • Universal Windows Platform: Windows 10 (64-bit), Visual Studio 2015 with C++ Tools component or later and Windows 10 SDK
