How Do I Get Decent FPS with forge?

[DiamondAge]

im running a GTX 1050 and when i use forge WITH ONLY THE MINIMUM mods needed for skyblock + 4 fps booster mods i get around 5-30 maximum, and in dungeons its unplayable i get 3 seconds per frame instead of frames per second. when i use lunar i get 160 fps with 0 fps drops. how does that make sense? i need forge with good fps
