i've got the digital version. Played through the conversation with Polly so far. The frame rate is definitely worse in the red room and during parts of the prologue, but I can't say it was too bothersome. I was more happy about the enemies not taking too many hits to kill! If the frame rate doesn't get worse than that section, I won't be disappointed. I could still pull off headshots just fine and this game doesn't require frame perfect inputs. and aiming won't matter once I get infinite ammo weapons anyway.
Now if I get crashes and out of bounds crap, that will suck.
