That's XeSS 1.1, there have been 2 version updates since then, does the same still apply to the current version? You can swap out the dll with XeSS in any game just like with DLSS.
At the same render resolution as the previous iterations, XeSS 1.3 is still slower than FSR2 and DLSS2 and there is hardly and improvement from Xess 1.2. This is why Intel seems to have tried to pull a fast one and renamed their settings.
