Yeah, I have Warriors Orochi 3 Hyper and I remember that being a big complaint about that port. While it's noticeable visually, I don't remember it ever affecting the gameplay. I don't think I ever got hit by an enemy I didn't see. It was more along the lines of I cleared an area, turned around and there were about 5-10 stragglers I'd missed because they didn't load in time.
And I thought I heard they had improved it from that release for this game. Though I wont know until I play it.
