Hi,

Recently I've put 2 Sapphire R9 280X videocards in my PC. The crossfire itself works fine and it does recognize the second card. But if I start Far Cry 4 for example, the AMD Catalyst control center doesn't show any activity in the second card. Only the primary card shows 100% activity and get's warm. Does anyone know how I can solve this problem? Or is it just normal that it isn't showing activity?

Thanks!

In terms of performance, AMD trumps nVIDIA in CFX/SLI perfomance since their 290/X cards do the action through the PCIE lane, practically doubling performance (rather than nVIDIA's 70-80% gain).

Generally speaking, yes, AMD do release less "game ready" drivers than nVIDIA.
And I say this as a GTX780Ti GHz Edition owner.
