Square Enix has confirmed that further PC production has been canceled, meaning that we won’t be getting anything new on the PC (apart from the Ardyn DLC). This means that the possible raytracing features are not going to happen either.
Multiple DLC for ‘Final Fantasy XV’ Canceled After Director Departure.
Three out of four upcoming installments to “Final Fantasy XV” DLC were canceled, Square Enix announced Wednesday during a special livestream broadcast. Basically, this also means since the PC production has been officially canceled, that the promised modding tools, Vulkan API and DLSS support will not be coming to the PC version. The Ardyn DLC was planned for a March 2019 release. Even though Square Enix did not reveal whether the promised modding tools or the Vulkan support (alongside DLSS) have been canceled, there's reason to worry here. The promised modding tools require a lot of R&D before releasing them and with Luminous focusing on a new triple-A title, we can assume that it will not dedicate enough personal to complete them and release them. After all, Tabata was the big force behind them and with him gone, there is no guarantee we’ll ever see them.
Moreover, NVIDIA may not even pressure Square Enix in order to implement Vulkan and DLSS support to the final game. After all, the official benchmark tool already supports DLSS so technically there is a version of FFXV out there that already supports it (it’s not representative of the game’s performance but that’s irrelevant to both NVIDIA and Square Enix at this point).
All in all, things are not looking great for Final Fantasy XV PC.
