you either need to upgrade or learn how to use computers, cause the game has no such problems.
the real problem is the recurrent crashes I am having after the veterancy patch.
You need ask Fahu about optimization
Dude in 2014 i play 4v4 and 3v3 with lags and a little freeze, after 2014 DLC i have same, but more terrible things in 2v2 and 1v1. WFA DLC kill optimization and another patch, so i know what i speak.
Crushes and optimization its the same problem.
