So I just tried playing DST again and upon creating a world the FPS would steadily drop until I couldnt move. I believe this only happens with wendy and the lag improve a little big after I used console commands to remove Abigail's flower.
I'd also like to mention my computer can more than handle DST and I've played it perfectly fine up until the wendy rework
Steps to Reproduce
Choose wendy when playing
