This is just plainly not true anymore, as far as the current gen consoles (PS5, XBox Series X) go.
I just searched for every major/notable PS5 game built on UE5 specifically (i.e., no UE4), which wasn't super difficult, given there are 31 of them. I might be missing a few, but that sample should be representative enough.
TLDR: 28 out of 31 UE5 games on PS5 have a performance/60fps mode, making it a ~93% share.
P.S. For posterity, here is the list of games I used for this sample:
> Fortnite, Marvel Rivals, The Finals, Tekken 8, The First Descendant, Clair Obscur, Lords of the Fallen, Remnant II, Immortals of Aveum, RoboCop, Black Myth: Wukong, Silent Hill 2, Silent Hill f, Wuchang, MGS Delta, Oblivion Remastered, S.T.A.L.K.E.R. 2, Hellblade II Enhanced, Mafia: The Old Country, Talos Principle 2, Jusant, Still Wakes the Deep, Cronos, Until Dawn post-patch, Banishers, Fort Solis, Layers of Fear, Quantum Error, ARK, and The Casting of Frank Stone
