To the current owners of an Arc card, is XeSS actually working for you in DMZ/Warzone 2?
I've been looking on YouTube and the seldom video I found which compared XeSS disabled vs. enabled on Arc in Warzone 2, there was no performance uplift or even slight regression. The videos are heavily compressed but I wasn't able to tell a visual difference as well which leads me to the suspicion XeSS is currently not working in DMZ/Warzone 2.

HardwareUnboxed has noticed the same:

We also took a quick look at DLSS 2.0 vs FSR 1.0 performance. We've excluded XeSS as we couldn't get it to work properly, even with the beta driver, so there are still some driver issues that Intel needs to work out.

Could any current Arc owner please give feedback with the most recent drivers whether XeSS is still not working at the moment in DMZ/Warzone 2? Ideally with FPS numbers to compare. I'm hovering over the buy button for a A750 but without working XeSS the downgrade from my current graphics card would be too much for me.
