Although I highly recommend using Windows 10, and working with a computer that's a bit faster than this to avoid long load times, the Minimum System Requirements are as follows:
- OS: Microsoft 64bit Windows 7.
- Processor: 64bit Intel compatible Dual Core CPU.
- Memory: 2 GB RAM.
- Graphics: OpenGL 4-compliant onboard graphics.
- DirectX: Version 11.
- Storage: 3 GB available space.
