And my point is that just because that bottom resolution is hit in a momentary instance, that does not mean the resolution is automatically lower overall. In fact they both average around 1440p, which would suggest that there are points where the XSX has a higher max resolution, or has enough instances where the resolution is higher to even it out. It is simple math really.
And that is where the problem with your claim lies. You want to split hairs for a momentary instance where the resolution drops to 1180p, but don't want to split hairs on the fact that certain special attacks can make the PS5 frame drop to 56 fps where the XSX maintains 60 fps. If you want to split hairs, you have to do it both ways, and that will end in a tie.
Digital Foundry and NXgamer both say it is.
As do others. Avg resolution is lesser on the XSX.
