New user. Need help figuring out how to speed a game whilst not speed the network aspects if that is possible.

Hi guys. I'm new to using GG and have been using it for wwe supercard. GG only really works up to about 30 speed after that the game just network errors. There are a few players that seemingly top the leaderboards and seem like they are playing on 300x but i dont understand how they are just not encountering a network error. I was wondering if its possible that they are speeding the game aspects up eg when the cards fight but not the network ones. Any help would be greatly appreciated.
