AMD: There is no such thing as full support for DX12 today
After yesterdays turmoil on a lacking DX12 feature for Nvidia AMD’s Robert Hallock shares that Fury X is also missing a number of DX12 features.
The good man replied in a Reddit thread on the DX12 Async shader/compute feature that is missing from NVIDIA’s graphics cards, and then claimed that there is no such thing as “full support” for DX12 on the market today. Which obviously was already known as AMD never claimed full DX12 support on all feature levels with their GCN architecture
“I think gamers are learning an important lesson: there’s no such thing as “full support” for DX12 on the market today.” said Robert and continued:
“There have been many attempts to distract people from this truth through campaigns that deliberately conflate feature levels, individual untiered features and the definition of “support.” This has been confusing, and caused so much unnecessary heartache and rumor-mongering.
Here is the unvarnished truth: Every graphics architecture has unique features, and no one architecture has them all. Some of those unique features are more powerful than others.
Yes, we’re extremely pleased that people are finally beginning to see the game of chess we’ve been playing with the interrelationship of GCN, Mantle, DX12, Vulkan and LiquidVR.”
When somebody asked what are the aspects of DX12 that the FuryX is missing, Hallock replied and listed them.
“Raster Ordered Views and Conservative Raster. Thankfully, the techniques that these enable (like global illumination) can already be done in other ways at high framerates (see: DiRT Showdown).”
So it is simple, currently no graphics card with full 100% DirectX 12 support, that means that some games are to favor AMD and others Nvidia.
I want to add thing here, yesterday Hallock was all over this downplaying Nvidia and evangelizing how good their GPUs are, and now he is taking a step back with these answers on Reddit.
It's all marketing mud-fighting and attacking each other these days in-between Nvidia and AMD. Fun fact: on the AMD GPU Tech day for Fury, I myself literally confronted and asked about the DX12 supported feature levels to Hallock, and in this case Hallock himself absolutely refused to give a valid answer at the time as he very well knew that AMD would not fully support DX12 either.

Marketing and hyperbole from both sides.

Infairness to AMD they showed the Fury as DX12 tier 2 (12_0) support so clearly it's not 100% DX12 compliant since it needs to be tier 3 (12_1) to be 100% compliant, i was kinda surprised that they didn't have it as tier 3 (12_1) but i guess they didn't want it to backfire if x doesn't work or perform like it should.

Which you can see here. So they have not advertised it as 100% compliant unlike their competitor.

Why is this news? We know it for very long time. Any kind of 'news' like this will not remove nVidia's problems.
And that comes from 2 simple things in regards of supported features:
- does feature improve visuals?
- does it improve performance?
- > and as result: is visual change worth performance impact? Or does it improve both visuals & performance?
So, you can take all 'new' nVidia's features which AMD did not implement (yet?), and see if you want those in games. Then, you can do same for AMD having stuff nVidia misses.
But since DX12 is mainly for purpose of removing different kind of bottlenecks (includes scheduling?), features which matter are ...
