These details can all be found on the DS Mechanical homepage.
The minimum required system specs are:
Supported operating systems:
Windows Server 2016 (64 bit)
Windows Server 2019 (64 bit)
Integrated graphics card (Intel HD graphics or AMD APU) with at least 1GB of graphics memory and supports DirectX 11, Shader Model 5.0, OpenGL 4.6 and with Direct3D Acceleration enabled.
Latest drivers must be installed.
Discrete graphics (NVIDIA Quadro, AMD Radeon Pro) with DirectX11 support and 2GB video memory renders objects well.
CPU wise, Intel i5 processors (like the 4th Generation, Quad core) provides enough power for quick geometry manipulations and allows background CPU intensive processes to run without any noticeable lag.
RAM: 4GB, but the more, the better.
