I'm genuinely curious, in zandatsu mode how many pieces do you get up too before the framerate drops too low to continue, for me personally i get roughly about 300 before the game starts slide-showing. Not unusual for my AMD FX processor, sometimes it doesn't get on well with games but aside from that the game runs like butter.
I'm closing in on the end game, and I have yet been in a situation where that big of a number has come up. It's a fun question though, but wouldn't are you going out of your way to make this many cuts?
not cuts, pieces, my wording is poor sorry. I've had a few areas where i get carried away and go mad with the mode but the easy way to test is during the tutorial where you have unlimited energy, i should clarify this isnt something that usually comes up for me in regular gameplay but i seen some people saying on the steam forums that they have loss of frames from the first cut.
