I'm not sure if that's why the benchmarks I linked to are so one sided. The thing about those benchmarks, though, is if you look at the nVidia scores they gained nothing at all with DX12 and they actually lost some performance in some cases. That makes no sense to me unless that particular game is only supporting DX12 features that are supported by the AMD cards and not nVidia. My suspicion, however, is that the game or the drivers are not properly optimized for nVidia yet. It's still just a beta and it's hard to base firm conclusions from it (yet).
Quote:On the other hand, Nvidia's cards are very much designed for DX11. Anandtech found that any pre-Maxwell GPU from the company (that is, pre-980 Ti, 980, 970, and 960) had to either execute in serial or pre-empt to move tasks ahead of each other. That's not a problem under DX11, but it potentially becomes one under DX12.
What was this BS about all NV cards from 4xx and up (Fermi and Kepler) "ready for DX12" that Poppin and Gstan loved to spout all over the forums??? Would these cards even do SFR rendering properly with games designed for DX12, with decent scaling? We'll see.
Even GTX 980 Ti (Maxwell 2.0) cannot do the job as nicely on DX12 as DX11, while AMD's cards receive about 2x performance boost over DX11. In effect, if Fury was included in the benchmark, AMD would be mopping the floor with TitanX at every resolution, let alone the 99% frame time.
