Having only used OpenGL and read Mantle's documentation (which is excellent) before, I'm having a very hard time learning DirectX12. The documentation is almost nonexistent, some of it hyperlinks on accident to pages of an old preliminary versions that differs greatly, and in code examples they've done mistakes such as trying to call CreateConstantBufferView using a command list instead of a device. So not only is it very sparse, it's plain wrong. This may not seem like a big deal to some since it's easily caught, but it's very exhausting to have to deal with wrong documentation on top of sparse documentation.
Concepts are not explained at all which makes learning the API very exhausting. You have to remember the whole API without understanding it, and try to interpret what it is you're supposed to do based on how the API has been layed out and based on what little has been said. It would be great if someone put in the time to create a short tutorial explaining concepts such as ConstantBufferViews which aren't even mentioned in the documentation except for acknowledging its existence. Some knowledge can be gained from DirectX11 which has better resources online, but not everything.
Therefore I'm hoping to use this thread to get answers to a few questions I have now and questions I may have later. Here are my questions:
1) What are the differences between Shader Resource Views and Constant Buffer Views?
2) What are the different ways for uploading data to the GPU and does the recommended manner differ based on usage patterns?
Thanks.
