edit: Basically it'd have been nice to see both neck and neck on DX11 with appreciable gains then on DX12.

Well that's really the point of DX12. It reduces CPU overhead and distributes the CPU workload across multiple threads. At the most basic level it's designed to alleviate any CPU bottlenecks, not improve GPU performance.

I'm sure once we start to see renderers implementing Async compute we will see GPU-side performance improvements.

not like software is need to make hardware run.

Basically AMD sucks at developing drivers within the DX 11 environment; either by lack of ability or finances to fund it. Where as Nvidia is capable of providing, for whatever reason, the resources to really maximize DX 11.

EDIT:

Not sure anyone should be surprised by this.

That's one way of interpreting that....rolleyes.gif

Another interesting commentary on drivers by a former Nvidia driver developer intern.

The most relevant part
Quote:
The first lesson is: Nearly every game ships broken. We're talking major AAA titles from vendors who are everyday names in the industry. In some cases, we're talking about blatant violations of API rules - one D3D9 game never even called BeginFrame/EndFrame. Some are mistakes or oversights - one shipped bad shaders that heavily impacted performance on NV drivers. These things were day to day occurrences that went into a bug tracker. Then somebody would go in, find out what the game screwed up, and patch the driver to deal with it. There are lots of optional patches already in the driver that are simply toggled on or off as per-game settings, and then hacks that are more specific to games - up to and including total replacement of the shipping shaders with custom versions by the driver team. Ever wondered why nearly every major game release is accompanied by a matching driver release from AMD and/or NVIDIA? There you go.

In short, the current API infrastructure and the methodology is FUBAR. Because the APIs obfuscate a lot of things the game devs write crappy (game) renderers, and then the driver teams have to try to fix those problems on their (driver) side.

Clearly, Nvidia's been more hands on with developers and most likely their driver-side fixes are just more comprehensive and game-specific. AMD traditionally hasn't been as hands on, with the exception of GE titles.

With DX12, the game devs will require greater knowledge and they'll handle more work. But that means the hand-holding by the driver team becomes less necessary and less effective, since DX12 won't hide things away like earlier APIs. The implication is that the driver teams from AMD and Nvidia will only be doing the bare minimum to support DX12 renderers.

Not sure how to take this. I have a month or two to decide between at least one Fury X/980 Ti/Titan X.

Hopefully more reviews like this come out in the meantime. Really rooting for AMD to catch up with DX12 but not holding my breath..

Think the best example is Flurry X vs 980ti. Even @1080p they are neck-to-neck under dx12.
