Ok, game loads all dGPU cards if you happen to have that (for what? Dual wield GPU lmao?). But that's something that only happens when you have insane PCs like mine.
I ran the mentioned cutscene on both a 5090 and 9070 XT. 110fps avg, 1% lows in the 60s as opposed to the normal 90s. Other than the game being super CPU bound in general I wouldn't call this "acting up"
