Many games released or upcoming using Unreal Engine 5 have no performance issues (e.g., The Finals, Marvel Rivals, Clair Obscur, Fortnite, Arc Raider..).
All controversial feature on UE5 are optionals.
Bad performances is mostly the result of bad developpement practice rather than engine flaw (and epic is doing a ton of shit work to provide excellent optimisation/Documentation on many side).
I'm personally so sick and tired from game influencer cringe who share misinformed (or ragebait ?) trought for click on twitter.
If you really love video game, share fact about it.
