False alarm. For some reason having crossfire disabled globally and in profile messed things up. Or at least I think that's what happend. But you guys should also talk to Respawn about getting multi-GPU working without stuttering.
FRTC was working great in this game until the latest driver. Now I have tons of tearing with FPS fluctuating from 70 to 120fps. I normally capped at 75fps and set monitor to 75hz. Haven't tested in other games yet
