Hmm, this takes some thinking for me to put into words.
When I enter any area in Kion, especially places with more assets like a city, I get quite a bit of lag. I think it teeters out after a bit, after things "load" but I'd have to recheck. It's hard to verify as I have to move around to test the FPS and things load in usually when I move. I did some checks and I think my computer is running on a SSD but I'd have to double check on that.
