I own both the Xbox Series X, for Gamepass and third-party releases, and the PS5 but I am continually surprised (read: disappointed) at how much better PS5 games tend to perform compared with the Xbox Series X.
It seems like Microsoft have some sort of mandate that Xbox Series X games *must* run at a higher resolution than PS5 (because the console is, on paper anyway, 20% more powerful) but this usually means its games run worse. This and Elden Ring are good examples but there are other third-party releases as well. I know the Xbox Series X has VRR support unlike the PS5 (which is why I no longer buy Ubisoft games and other third-party releases that have inconsistent framerates and/or screen tearing on Sony's console) but, c'mon, surely achieving a 99.999% stable framerate is way more important that having a higher pixel count that no-one would ever notice outside of a Digital Foundry tech video?
Of course, owning both consoles means I have a choice of which one to buy games for but currently we have PS5 games performing better but those 1-3 fps dips below 60 fps manifest as judder because it doesn't have VRR and on Xbox Series X we have worse performing games but VRR can be used to save the day. The latter is clearly better for people wanting a smooth gaming experience but really neither console is in a ideal position. VRR should really only be there to mask the inevitable framerate drops every game has from time to time, not really used as a band-aid for lazy or poorly optimised games such as those from Ubisoft (who should have The Masters of Screen Tear as a byline in my opinion!) and From Software.
