My computer has all of the requirements to play Reforged version, but game keeps lagging and getting stuck no matter what I do!
I tried to close all other applications to better maximize my internet connection, lowering graphics, tried to disable some functions, but none work. The game keeps lagging, and I am not able to play without getting frustrated every 5 seconds when the screen freezes.
Please help! 
Give Blizzard a call, since they released an unfinished and unoptimised game. U just have to be lucky for it to play fluently nowadays. Even though the game used to play fluently on any 15y old computer.
