I don’t know if it’s 60 FPS, but just this Sunday I was helldiving on Meridia with a full party of 4 doing dark fluid runs on 9 and I didn’t have any lag or issues playing. And I play docked with the resolution set to 1920x1080 so it’s certainly more aggressive on the hardware than in handheld mode at 1280x800. All this is to say it feels smooth and lag free (I unfortunately just haven’t bothered scoping out FPS; too worried about the Charger that’s aiming to slap me under one of those bile titans 😅)
Rightfully worried IMO
