DirectX Device CAPS

In the DirectX 10 documentation, I read the following:

"The functionality bits of legacy hardware (caps) have been removed in favor of a rich set of guaranteed functionality that targets Direct3D 10-class hardware (minimum)."

"Removing CAPS Bits - Guaranteed Basic Direct3D 10 Feature Set."

Where can I find the list of "guaranteed functionality / basic functions" that they talk about?

For example, in DirectX 9, I can look at D3DCAPS9.MaxTextureWidth to find the maximum width of the texture. How do I know the maximum size that all DirectX 10 devices should support?

There are no caps, so you just need to assume that your hardware (provided it is compatible with the DX10) will support the full range of DX 10 features .

This means that, for example, support for texture sizes of 8192 ^ 2 is guaranteed. 3D textures must support 2048 ^ 3.

However, keep in mind that the hardware is allowed to implement this in the software - it must support this feature, but there is no guarantee of speed.

The minimum values ​​are available here.

As you can see from this link, the maximum sizes of U / V textures that the card should support are at LEAST 8192x8192.
