Unreal Engine 4 is crushing for me

  • Hello,
  • i realized that my GPU is running on
    99% same as the Vram is on 80-90%.
  • My main GPU got damage and i need to
    send it RMA.
  • Now i’m using a GTX460.
  • CPU: 2x 2683 v3
  • RAM: 32GB DDR4
  • Only SSDs inside.
  • Can i somehow make Unreal engine use
    less Vram?
