CRYENGINE might run on the integrated GPUs from Intel and AMD (3rd Generation Intel i-Core CPUs and above, AMD APUs that support DX11), but they are not officially supported and we advise you to not run CRYENGINE on integrated Graphics solutions due to non-optimal performance.
Please also keep in mind, that integrated GPUs share RAM with the CPU, thus resulting in less available RAM for the CPU and OS. Hence, 4 GB of RAM might not be enough and therefore minimum System Requirements will not be met.
Furthermore, for full DirectX 11 compatibility not only does the OS have to support it, but so does the GPU and at a hardware feature level. Hence, it doesn’t matter that the Windows OS is DX11 capable, the GPU MUST be too.
Check your GPU manufacturer’s website for more info (NVidia or AMD)
