CPU: x86-64 Intel or AMD; at least one 2 GHz core for SD, 2 cores for HD, and 4 cores for 4K.
GPU: OpenGL 2.0 that works correctly and is compatible. On Windows, you can also use a card with good, compatible DirectX 9 or 11 drivers. We do not have a list.
RAM: At least 4 GB for SD, 8 GB for HD, and 16 GB for 4K.
