Who is playing AC4 with CFX? Whats your performance?

Nvidia users were also having SLI problems. Nvidia launched new drivers and the problem´s solved.

So, for now, just play with CFX disable till AMD launches a new set of drivers.

 

same as me m8 i think the r9 cards need better driver optimization

 

I get negative scaling with crossfire, I wouldn't be surprised if you guys are too.

 

Remove the beta drivers and do a CLEAN install of the 13.9 official ones.

Crossfire enabled here.

 

I'm not running it crossfire, but I'm surprised about all your performance data. I'm using a single 6950 unlocked, and I can set almost everything to the max. The only thing I had to cut back is the smooth shadows(I have them on high but not soft) and I have SMAA for antialiasing and Vsync is off. I got frames 25-40 in open areas and 50-60 in the offices. I think soft shadows are not that important as the extra detail in the textures or the extra foliage and all the rest extra effects... The game looks great the way I play it. So my suggestion is check your shadow settings, see if it's works for you like that.
