Amazon recommends a system with the following specifications for developing games with Lumberyard:
PC running a 64-bit version of Windows 7 or Windows 10
At least 8 GB RAM
A minimum of 60 GB hard disk storage
A 3 GHz or greater quad-core processor
A DirectX 11 (DX11) compatible video card with at least 2 GB of video RAM (VRAM)
As mentioned above, currently, there is no support for running Lumberyard on a Mac OS or Linux computer.
The game engine is a very large and complex software suite. You should take the system requirements seriously and, if at all possible, exceed the minimum requirements.
