Memory Leaks in FH4 making the game unplayable

Whenever I am playing this game my memory usage is at 100% and it causes fps stuttering making this game unplayable. It only happens on this game and don’t know why. Please leave a comment if you know how to fix

Well helpful would be to tell how much memory you have and whether you are talking about RAM or Vram ? Although i assume its RAM

8 gb of ram
