I have a 1050ti and I can play it on low graphics settings at 1080 with no depth of field. I've gotten to about city stage #5 or so and I feel that it's playable. It's not pretty but good enough to get a feel for the game and learn about the new stuff.
For me - not at all. I don't have a computer that meets their minimum system requirements. I really feel like the cycle of newer games requiring more hardware is pointless and wasteful. I wish publishers would focus on good game design and make their games accessible to people without high-powered gaming hardware.
It takes a lot of time and effort to pare down the assets and add tricks to make a game look good on lower hardware. Targeting current-gen GPUs means the devs get a better game out in the same time and budget.
