Now here is a pleasant surprise. While Square Enix stated that the development for the PC version of Final Fantasy XV has been ceased, NVIDIA has just released a new driver that adds Deep Learning Super Sampling support to it.
NVIDIA claims that this DLSS support is still in a beta phase, meaning that there might be additional performance boost in future drivers. Right now there is no DLSS option in the game, meaning that Square Enix will release shortly a patch that will add this setting to it.
To enable DLSS, download the FINAL FANTASY XV WINDOWS EDITION update once available on Steam, open the in-game options menu, set your resolution to 4K and enable DLSS under your Anti-aliasing settings.
Furthermore, this driver fixes the following issues.
- [SLI][TITAN Xp]: SLI is disabled by default after installing the driver. 
- [TITAN V][NVIDIA Control Panel]: The Workstation->Manage GPU Utilization page appears when it shouldn’t. 
- [Rocket League]: The game launches to a white screen with audio in the background and then crashes. 
- [Battlefield V: Day0 97][Ansel]: After being moved all the way to the left, the Ansel field-of view (FoV) slider stops following the click-and-drag mouse movement.
- [Hitman 2 Silent assassin]: There is flickering texture corruption in the game.
- [Notebook][3D games]: Frame rate of 3D games may drop to under 30 fps on notebooks. 
Those interested can download the NVIDIA GeForce 417.35 WHQL driver from here, and we’ll be sure to test Final Fantasy XV with and without DLSS!
