1.7 packs could usually get by with 4gb RAM. Changes to the base game code require 1.10+ packs to use more RAM, usually around 6gb is enough.Is modpack 1.10.2 like sky factory 3 need 4gb ram to play or something else like cpu,video card to play or just need ram ? Also when i play modpack 1.7.10 it was so lag with screen loading and took about 30 mins to switch to main screen , what that's problem or just my ram too low
( Sorry my english bad )
