requiring people to upgrade from Windows 7 to Windows 10 wouldn't have any merit anyways, because... 1- there is nothing in the minimum requirements about distinguishing features between the two. 2- and if there was a difference, it would be DirectX 12. but even then that point is moot because...Cyberpunk 2077 runs solely on DirectX 12. Microsoft did release an API for Windows 7 to call on DirectX 12 functions. so honestly, there is literally no reason for bungie to make that requirement. And since Bungie is owned by xbox game studios....which is owned by Microsoft...they can easily integrate the correct API if that was their future excuse.
