Today, Microsoft is announcing a new version of its gaming and multimedia API platform, DirectX. The new version, DirectX 12 Ultimate, largely unifies Windows PCs with the upcoming Xbox Series X platform, offering the platform's new precision rendering features to Windows gamers with supporting video cards.

Many of the new features have more to do with the software side of development than the hardware. The new DirectX 12 Ultimate API calls aren't just enabling access to new hardware features, they're offering deeper, lower-level, and potentially more efficient access to hardware features and resources that are already present.
For now, the new features are slated largely for Nvidia cards only, with "full support on GeForce RTX"—the presentation you're seeing slides from actually came from Nvidia itself, not Microsoft.

Meanwhile, AMD has announced that its upcoming slate of RDNA 2 GPUs will have "full support" for the DirectX 12 Ultimate API—but not any prior generations of AMD cards.

DirectX Ray Tracing, aka DXR, isn't brand new—DXR1.0 was introduced two years ago. However, DirectX 12 Ultimate introduces several new features under a DXR1.1 versioning scheme. None of DXR1.1's features require new hardware—existing ray-tracing-capable GPUs merely need driver support in order to enable them.

I assume this all only applies to the most recent generation of graphics cards? RTX cards are mentioned but since nothing else is so I have to assume it is exclusive to them.

Microsoft released the latest DirectX 12 Ultimate technology a few months ago and it announced a huge step in computer graphics.

Now, Microsoft revealed a little bit more details about DirectX feature level 12_2 and which cards will support this new technology.
If we lost you on the feature level moniker, let’s clear it out. A feature level for DirectX specifies exactly which capabilities can be handled by a certain GPU.

Advancing from 12_0 to 12_1 and 12_2, a graphics card would have more advanced features and the latest DirectX 12_2 feature level was defined as DirectX 12 Ultimate.

Just to be extremely clear, Microsoft also presented the set of features that a DirectX feature level 12_2 card will have: [...]
Just to remind you of the major improvements for the new DirectX 12 Ultimate, they are Raytracing, Variable Rate Shading, Mesh Shaders, and Sampler Feedback.

Microsoft: New in DirectX— Feature Level 12_2

Successive feature levels are supersets of functionality. For example, feature level 12_1 includes all the capabilities of feature level 12_0 plus some more things. And, of course, feature level 12_2 includes all the capabilities of the ones before it, plus some new things. Now it’s worth mentioning that the jump from 12_1 to 12_2 is huge, if we’re being honest.

https://mspoweruser.com/microsoft-opencl-opengl-compatibility-packs/

Back in March, we reported that OpenCL 1.2 and OpenGL 3.3 support is coming to all Windows and DirectX 12 enabled devices.

Microsoft has now released a compatibility pack that allows you to run any OpenCL and OpenGL apps on a Windows 10 PC that doesn’t have OpenCL and OpenGL hardware drivers installed by default. If you have a DirectX 12 driver installed on your Windows 10 PC, supported apps will run with hardware acceleration for better performance.

For now, only certain apps can use this compatibility pack. Microsoft also mentioned that Windows Insiders can get an Insiders version of this package that allows more apps to use it.
