I'd just assume they are 100% relying on MetalFX to hit that framerate. We will find out this week I guess.Dunno about Genshin. They might wait and see see how Honkai goes first.
I'm somewhat curious about the 120 Hz support though. Be interested to see how a base M series can perform.
Genshin can get 120 fps on an iPhone 13 Pro Max, but that's using a considerably smaller screen using an A15 Bionic.
