So Crossfire issues have been fixed!!....
BUT... as you are probably also aware the latest Catalyst Drivers since beta drivers 14.11.2 - hard disabled crossfire for Far Cry 4 until FC got their crap together.
Quote:
The AMD CrossFire™ profile for Far Cry 4 is currently disabled in this driver while AMD works with Ubisoft to investigate an issue where AMD CrossFire™ configurations are not performing as intended. An update is expected on this issue in the near future through an updated game patch or an AMD driver posting.
So I am running the 1.6 patch, alone, and still only one of my 2 cards fires up... it seems that FarCry is leaving or had to leave it up to AMD to re-enable crossfire with a further driver update.
So having working crossfire with FC4 requires either using pre-Omega buggy as sh..snot drivers, or....
as i just realized works...
rename FarCry4.exe to ANYTHING ELSE and CCC will not block crossfire from running!
renamed mine to FarCry4-2.exe and it works!!
EDIT...
it seems that there may still be a patch or driver update required before this fully works. while both cards fire up full throttle, there appears to be a memory leak now. game filling up all available memory in my system and freezing the game.
