New to Direct3D programming: 11 vs 12

For a newbie in D3D programming, should one just learn D3D12 directly or is D3D11 necessary before diving into D3D12? Assuming starting from scratch and decent knowledge of C++, which way should I go?

How to synchronize CPU and GPU using fence in DirectX / Direct3D 12?

I'm beginning learning Direct3D 12 and having difficulty in understanding CPU-GPU synchronization. As far as I understand, fence (ID3D12Fence) is no more than a UINT64(unsigned long long) value used as counter. But its methods confuse me. The below…

Is fullscreen really better than windowed mode in a Direct3D 12 application?

I'm trying to learn Direct3D 12 to do some simple 3D graphics for fun. I've heard that pure fullscreen is the way to go for maximum fps, but now that I'm testing it, fullscreen seems way, way worse than windowed mode. For example, a static color on…

Can I change binding points in a compiled D3D shader?

I have an HLSL shader that defines some resources, say a constant buffer: cbuffer MyCB : register(b0); If I compile my shader, I will then be able to query the register through the reflection API. But is it possible to change the register (for…
