im using a gtx 1650, i have 16gb ram, i dedicated 6,5gb of ram to the game, my cpu is i5 10400 i get constant 150+ fps and it freezes sometimes and when i click esc freezes too, its really annoying and i want to fix it, its in ftb stoneblock 1.16.1, maybe its because i added optifine mod, because i wanted shaders, but after adding optifine i didnt get the shaders folder.
