I agree but not everyone can afford (or wants to have) 2 computers and some people need laptops. A laptop with a GTX 860M should easily run this game, but he needs to get the latest driver from the manufacturer or a pre-optimus driver release (or manually tell it to run the 860M for hardline...otherwise the computer will tell him the 860 device was removed when the driver determines (for whatever reason) that the IGP should be used to play.
An Optimus vs a great many high intensity games is a carnival sideshow of frustration. The owner has to find every one of several settings in the Geforce Control Panel and set them all to force the GPU to wake up, and do it every time he buys a next new game, and today's typical laptop owners simply do not usually have the level of enthusiasm for technical matters to follow through. Instant gratification has ruined that generation of would-be game players.
Oops, sorry, I got up on my apple box and preached without covering everything. If a person has to have a laptop for travel, make it a cheap and basic one to save money for the compact size stationary gaming system, keep it until it quits, and the total cost will be less than replacing laptops every three years, by more than enough to support the separate gaming box.
