That's great news since AMD really does need a fix for crossfire. Have been running the game on Ultra @ 2560x1440 and ended up disabling CF since card usage was down to the mid-40s % wise. Disabling it did help stabilize the FPS though to a smaller gap between low-highs. Now it's going from 37-48 FPS compared to doing 24-38FPS with CF turned on. The single GPU is only using 97% load at any given point as well. The cards are overclocked though to 1150MHz core and 1700MHz memory, which lead to more stable higher FPS then at stock. At stock the FPS would be reduced to average 28-35 with CF disabled. As for ingame settings, I have everything on max except the AA which is Temp SMAA, anything above that hammers the FPS down to 19-26FPS. Haven't done too much research into the GPU Buffer Frame, but I reduced mine down to 1 Frame, haven't seen much of a difference performance wise.
