Whatever DLSS setup they have implemented it is completely bogus.

In other games, I can see a noticeable difference in GPU utilization depending on whether DLSS is off/on.

Not so in XIV. No matter what I set, my 3080 just doesn't give a hoot.

I also find it very strange that XIV can tax my GPU to 100%, barely managing a stable 60FPS @ 4K with (supposedly) DLSS active, considering this game doesn't even employ any ray tracing. o_O
