Since the crimson update my PC hasn't been utilizing crossfire while playing Source Engine Games (CS-GO, Dota 2). I am currently using NZXT's CAM software to monitor my GPU loads. When playing GTA V or WoW both cards are being used (I check the loads on the cards) but when playing CS-GO or Dota 2 only 1 card gets put under load.
Things I have tried:
Turning off Crossfire then turning back on
Turning off ULPS
Re-installing my drivers
If anyone could assist me further it would be much appreciated.
