I'm a definite proponent of fairness in gaming but that's not Nvidia's fault imo, that's Microsoft for labelling the HBAO+ proprietary method as simply Ambient Occlusion and allowing it to be used to AMD cards. If it 's indeed HBAO+ as all indications point to, it's just not ever available on AMD cards. Just another retard moment for MS on this shambles of a release.
I am with you on this and seems WCCF jumped the gun as usual, also that WCCF journalist is err a bit biased towards AMD to say the least
Even on Steam there are those able to use AMD cards with HBAO+ active but have problems with SSAO *shrug*.
Now there is an update to that article to say AMD report they were not given a copy/involved in QA their hardware, but this reminds me of the racing car situation where AMD originally blamed NVIDIA Gameworks and then blamed the developer for not being proactive with them.
I just get the feeling in these scenarios where the ball is dropped, AMD expects the developers to be proactive and go to them rather than AMD spending time/resources engaging first.
I can see AMD's point and in an ideal world it would work; but developers have a serious tight budget and critically project time frame/milestones, so AMD need to work more like NVIDIA in the business development model and aggressively engage developers and ensure they have a seat at some point on key games (I appreciate they do not have the same budget allocation as NVIDIA so need to be more selective on games but this does not stop them working with all the major developers to agree which games and when to work with them).
But AMD do like to blame everything on either NVIDIA or developer
I remember Rise of the Tomb Raider Pure Hair showed a large visual improvement over that of NVIDIA and yet both had exactly same % performance loss (one review showed comparison to snow and hair - snow was really nice), NVIDIA response was to work more to get a future update out and no comments at the time.
Edit:
I also remember reading a review that showed some strange GPU dynamic memory behaviour for AMD with Gears of War Ultimate, might be something as well or not.
