↖ Quick Notes That Matter

A couple of small details in the list are easy to overlook but important in practice:

• 64-bit is required across the board—both your CPU and Windows installation must be 64-bit.
• DirectX 12 is mandatory, so compatibility depends on DX12-capable hardware and drivers.
• Intel Arc GPUs call out ReBAR (Resizable BAR) specifically. If you’re using Arc, ReBAR should be enabled to align with the stated requirements.
• Internet is not optional according to the specs: a broadband connection is listed for both minimum and recommended.
