The game engine seems not to be much up to current standards, not very optimized on many corners, so it's not running as smoothly as some better tended games. I got a pretty strong gaming laptop with GeForce GTX 1070 8Gb, all on Ultra settings, about the same FPS, and depending on zone and player amount, can drop as low as to 24.
