Its amazing how 1 patch with a new API can drastically and i mean drastically alter the gaming Landscape...
What i will say is this, AMD for many years have built hardware that has never fully been exploited, some of these new API's can actually manage to exploit and utilise that hardware and it is paying insane dividends..
Yes we have only seen a small glimpse, but if this is what is to come, then times are good for AMD, of course we need to see how Nvidias cards cope with Vulkhan etc when its implemented to support their hardware correctly...
Will be interesting to see how Vega is when its released, and the adoption of Vulkhan and DX12 going forward, if the API's get good exposure in some high volume AAA games, they could well become the norm going forward, and if AMD cards have the traditional edge going forward in these titles, you may well see a major shift in marketshare.
