OK guys,in this section there are a lot of people who have problem with BO2(like crash when the treyarch logo appears ecc.).
this guide(took from internet) i think should work on all BO2(bought,skidrow version ecc),with mine(skidrow eng version) worked.
1.If you have a nvidia,with optimus technology,go to nvidia panel,3d options,program options,select t6sp-zm-mp and select nvidia as primary(global option)
2.go to date and hour settings and put the day on which you installed the game.
3.play and enjoy.
