Right so, i've gone through loads to speed up my computor including game booster, defragging it, and advanced system care but it still takes like 5 minutes to load the game! is there anyway i can make it load faster? cuz' i've already tryied EVERYTHING i can think off

When The Game Load Search Crossfire By:

1. Press= Ctrl+Alt+Delete (Task Manager Appeared)
2. Then Go Applications.
3. Looks For Crossfire and Then Right-Click (Set Priority)
4. Makes Its Low.
