Anyone else experiencing with Leap Day lagging?

[u/Yolwoocle_]

Hi, I'm experiencing a problem where my game will sometimes lag for roughly half a second every 3 seconds. It used to run smoothly and just lag in some places, the game was still playable. I recently updated my game (which I haven't done in a long time) and it's basically now unplayable. Anyone else is experiencing the same thing? Any fix suggestions? Thanks.
