For me it was pretty bad. Especially in DX12.. every time hitting objects for the first time, or doing abilities... loading into new areas.. DX11 was a bit better.. but still not good.I've beaten the game back in Sep and haven't really seen much stutters in it. Granted I've played in 60Hz, maybe they've appeared only in higher refresh rates?
Now DX12 is smooth as butter first time through doing anything. Wish it was like this the first time I played it.
