Questions tagged [direct3d12]

DirectX 12 introduces the next version of Direct3D, the 3D graphics API at the heart of DirectX. This version of Direct3D is faster and more efficient than any previous version. Direct3D 12 enables richer scenes, more objects, more complex effects, and full utilization of modern GPU hardware. It is supported on Windows 10 and Xbox One.

GetCPUDescriptorHandleForHeapStart stack corruption

I've stumbled upon a rather unusual problem while programming with DirectX 12.0. No research so far has been insightful. I am programming using C (not C++). It would appear the official DirectX 12 headers support bindings for both C and C++, however…

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?

Which format to use for a shader resource view into depth-stencil buffer resource?

The depth-stencil buffer resource is defined as DXGI_FORMAT_D24_UNORM_S8_UINT format. I would have assumed that to create a shader resource view (SRV) into that resource would require the view format to be described either…

What is the point of D3D12's SetGraphicsRootSignature?

I am a little confused about the existence of the ID3D12GraphicsCommandList::SetGraphicsRootSignature method. From what I understand of this MSDN page, it seems that the only valid usage of it is to always call it after SetPipelineState, giving it…

Getting display's refresh rate on D3D12

I am porting my code to D3D12 from D3D11 and I'm trying to obtain display's refresh rate on D3D12. I use the refresh rate for precise animation timing (this is a hard requirement). This code works on D3D11: HRESULT GetRefreshRate(IUnknown* device,…

How to write to the image directly by CPU when load it in Vulkan?

In Direct3D12, you can use "ID3D12Resource::WriteToSubresource" to enable zero-copy optimizations for UMA adapters. What is the equivalent of "ID3D12Resource::WriteToSubresource" in Vulkan?

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…

HLSL Shader compiles, but crashes when creating compute pipeline state

I have a D3D12 compute shader (Shader Model 6.0) that compiles successfully. When I compile it with optimization disabled (/Od), it runs fine, the outputs are correct. When I enabled optimization, it also compiles, but crashes when I am creating the…

Setting multiple descriptors in a descriptor range in Direct3D 12

First of all, my understanding of a descriptor range is that I can specify multiple buffers (constant buffers in my case) that a shader may use, is that correct? If not, then this is where my misunderstanding is, and the rest of the question will…

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…
