I have 3 gigs of ram allocated to the launcher my computer shouldn't have a problem with that, Here are the specs for my computer

 

 

core i5-4430 3.00Ghz

 

12 GB RAM

 

2 terabytes of storage

 

windows 8

 

Intel HD graphics 4600

 

Can anyone help me or has someone already fixed this problem. any help help would be appreciated
