Feral Heart

My Feral Heart game has been very laggy lately. Each time I or someone else walks, runs, or crawls, my game lags. Ive turned off/down everything I could, redownloded FH, used the vanilla FH before downloading any mods, and nothing has worked. No other games I have is lagging, its just FH. I have a new, laptop, not even used for a year. And its not just how many players are on, I can be in Lonely and it still laggs. Is there a way to fix this? Id like to play a smooth Feral Heart game once again.
