sooner or later it will be fixed
And this is taking from the: Next patch info: Finally fixed the landscape stripes bug:grin:

I am afraid the key word is "landscape".

I've my doubts too, because else they would have used the word "horizon" instead of "landscape". It looks like the blue stripes belong to the ATI driver department because the blue lines only appear with 69xx cards. But it looks that ATI doesn't give home and thinks that their customers can't install their drivers properly. I hate it that ATI doesn't take its customers serious so far. I hope they will change their attitude toward this problem and its customers. Next time I serious consider buying Nvidia although the 6970 is serious bang for the buck.

I purchased the card and the ram

My new specs:
Win7 64
Ci7 920
Asus P6T Deluxe
HD6970
6Gb (3x2Gb) PC3 10666

Everything is stock except for the video that comes slightly OC'd (940MHz)

I now run the game @ 1680x1050
All graphic settings are on except
AA:2x
Epilepsy = off
SSAO= off (what is this?, should I turn it on?)
Vsync = off (works well, everywhere but London)
Buildings amount = High
Forests = Medium
I get 32fps adv on the black death.
Rooftop level in London will average 20-30 w/ dips in the teens that exhibit some stutter. (less stutter than I got @ 60fps when I had 3Gb RAM)

Otherwise the game is jaw-dropping-gorgeous and I stay in the 60-100 fps range most of the time. Yes, I get the horizontal blue lines; I've emailed AMD. Needless to say that all my other games are much improved. Essp. Dragon Age 2 (Dx11)

I would recommend this card.
