Hi i have 2 r9 280x (crossfire), As an active crossfire? In te previous version crimson he was activated in settings-additional settings-crossfire but now i can't find it. Can help me? Thanks
With Crimson, CrossFire is enabled all the time by default.
To turn it off in applications you don't want to to run with, click on the game in question within the Gaming tab in Crimson, and select Disabled under "AMD CrossFire Mode". Everything will use Default, so a profile or like the old days you can still force AFR etc.
I'm not sure if this is only the case for X2 cards or everyone on CrossFire. Hope it clears things up for you
