Rivalry between AMD and Nvidia is nothing new and even the slightest of news  giving one company an edge over the other, is talked about extensively by fans.

Just recently, it came to light that Nvidia cards don’t properly support DirectX 12 Async Compute features. This sparked a lot of debate between fans and AMD people thought they had an edge. However, that isn’t the case.

Similar to Nvidia, AMD won’t support some features of DirectX 12 as well. AMD’s Robert Hallock said that there is not a single graphics card with “full support” for DirectX 12 in the market right now.

He wrote:

I think gamers are learning an important lesson: there’s no such thing as “full support” for DX12 on the market today.

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.

He went on to say that every GPU comes with its unique architecture, and none have full support for DirectX 12 right now.

Now the question is, what features does AMD hardware doesn’t support? According to Robert Hallock, Raster Ordered Views and Conservative Raster are features that are missing.

I’m not very technical when it comes to such matters but as far as I know, techniques that these features enable, such as Global Illumination, can be implemented in other ways.

How exactly? Well, that is a question for another day.
