exactly ... and what's worry me most that the same thing happened with AC3 ... not a single driver for it until now !!! and please do not tell me that AC3/AC4 have already work with best performance possible for AMD cards because its not

haha yes ac3 boston lag was never fixed for AMD although multiplayer is good but for now ac4 looks so broken for AMD gpu ..... Horrible Fps drop in multiplayer and single player not running like awesome .... Amd releasing new better gpu but their support is so bad as compared to Nvidia ...... With this lag sometimes i regret my decision of buying amd

AMD has good cards but their support is horrible to say at least >.< not to even mention their crossfire profiles.

AC3 and AC4 both have the same problem - they don't work properly with Crossfire.  Beyond that, the limitations are the CPU, no matter how fast it is.

AC3 in Boston, in particular, can never be solved by any driver update, since it's a huge CPU bottleneck.  I estimated that getting a solid 60fps in the CPU-bound areas would take something like an 8GHz i7 processor.

The same kind of CPU bottleneck exists in AC4, though it's less severe.  Playing at 2560x1600 with a single 7970 (since CF doesn't work properly), I was GPU-bound far more than CPU-bound throughout the game.  While the frame rate was occasionally 30's, it felt smooth overall.

This is with the 13.1 drivers.

You can't fix a game's design with new graphics drivers.  All you can do is hope that the next title uses Mantle, which would probably eliminate most or all of the CPU bottleneck in titles like these (via better draw call throughput).

Man agree with you ...... ac3 has only problem for me in my 7770 is boston problem .. other than that its running fine for me ..... but ac4 seems horrible for amd user. You said graphics drivers won't solve this problem much but atleast they have to do something about it. People buying Amd gpu's ( which are good thats why i buy it too) but thier support is horrible as compared to nvidia for sure. I can say this because i have nvidia previoulsy !

AMD : hardware ... software

Nvidia : hardware ... software

Overall performance in games : AMD ... Nvidia

Doesn't make sense but I achieved a massive performance increase by.... downgrading driver versions!

I've got 2x 7970 3Gb. I forced CrossFire on in the control panel (Select the 'games without a profile' option) With the following:

2560x1440
Env: Very High
Texture: High
AA: Off or MSAAx4 (see below)
Shadow: Very High
Motion Blur: On
AO: SSAO
God Rays: Low
Fog: On
VSync: On

I was lucky to lock to 30fps on 13.11. It generally managed it with AA off but not on.

Downgrading to 13.9 - 4xMSAA produces a lock on 30. If I turn AA off it runs at 60fps out at sea and on islands only dropping to 30 in dense forest or the larger locations.

It's not an ideal solution if you play other games that are improved by the new driver - I just downgraded to complete the game.

13.12 drivers released today and not a single word on Assassins creed 4. AC 4 support will never see the light, just like AC3

What constitutes AC4 support?  Crossfire does not work properly.  That is, it works, but performance is below a single card.  Same as it was with AC3, and I really don't think AMD can do anything about it.  It's an Ubisoft problem.

Beyond that, the game works perfectly with a single card.  At the higher detail settings (especially environment), the game is very CPU-bound.  Definitely not anything AMD can remedy.

So what is it exactly that you want to see done?

    We would like crossfire support with optimization to scale for starters. Thats called support.
