the modpack makes the game run at the best fps possible but with some features like shaders and better f3 menu and fullbrightness toggle and optifine like dynamic lighting and ofc zoom and if you put minecraft in the background for lets say watching youtube its gonna change its fps and lowering it so you can watch youtube without problems/laging

and you have to go in modmenu and change lampdynamiclights mod from fancy to fast to get better fps
