Impressive work from AMD! Nvidia really needs to stop slacking and start optimising their drivers/Gpu's for next gen (or current gen, however id say next gen as currently there are like 1-2 games built from scratch on Dx12/ Vulcan) API's. Otherwise if AMD has much better performance for cheaper price on new API's they might easily win a big chunk of the market back from Nvidia. I mean honestly, Dx12 should give INSANE performance gains, however what we see in all of those "Dx12 updates" for various titles is actually NEGATIVE (wtf) scaling. Shame!
However all in all this is good news, competition always drives development and makes them Work for their money. Can't wait to see Nvidia's reaction after release of Vega.
the game was faster on radeon hardware even in DX11. and honestly i don't think there is any problem with nvidia hardware. DX12 is mostly solving AMD problem in extracting more performance out of their card. RX480 for example is rated at 5.1tflops while GTX1060 was rated at 3.85tflops. but in majority of games RX480 performance did not reflect the raw performance between the two.
