But those PC features in Ubi games, like HRTS, VXAO, VXGI, HBAO+, the ray marched fog in Watch Dogs 2 etc. work best and oftentimes supported only on Nvidia hardware, they are not open source. So they'd either have to ditch Nvidia marketing and support (which is probably a good source of income for the PC port) then implement similar features themselves. Which is possible, I'd expect something like that from id for example, but not from Ubi titles (which have a long history of partnership between Nvidia and Ubi). So if i was a betting man I'd expect first parties to take advantage of the hardware, and third parties to simply scale across all platforms depending where each console hits bottlenecks.
