I don't think that Cyberpunk 2077 will be Windows 7 compatible.

I believe very strongly that it will require DX12 and Vulkan support at least.

There are no official system requirements as of yet. But if you're rocking Windows 7, I'm going to go ahead and assume you have a relatively older PC with older hardware. Perhaps it would best to look for a cheap PS4 or Xbone in a pawn shop. You can get them for around $150. (Much less than the cost to upgrade a PC.)
