The problem with implementing DLSS is that the game has no modern anti-aliasing techniques. DLSS and FSR 2.0 both build upon the temporal image data used by TAA. I'd love to see DLSS, FSR 2.0 and TAA all be added into the game but that requires a series of game engine improvements for Square Enix to implement that aren't likely to happen until 7.0 at the earliest.

I wouldn't say DLSS is entirely necessary though and the engine improvements mentioned above would likely yield performance increases across the board anyway. That said, I still average over 60 FPS in combat playing on a Ryzen 7 5800X3D, 32GB DDR4 3600 MHz and RTX 3080 12GB at native 4K but I'm just massively brute forcing spaghetti code.
