Where is the XeSS option?

So, I have an Arc A750, and I wanted to enable XeSS in this game.
Researching about it, it seems like it had XeSS in the graphical options, but I can’t see it:

Do you guys have any idea on how can I enable it?

Your research are wrong. Game only has DLSS support which is for Nvidia RTX cards.

The current DEV client still has the XeSS option but it’s disabled and cannot be changed.
It’s pretty much WiP feature that is yet to be announced/added.
