The Vulkan and DX12 graphics devices now support bindless descriptors in Wicked Engine. Earlier and in DX11, it was only possible to access textures, buffers (resource descriptors) and samplers in the shaders by binding them to specific slots. First, the binding model limitations will be described briefly, then the bindless model will be discussed. Binding…

The article discusses the limitations of the binding model in Vulkan and DX12 graphics devices and introduces the bindless model as a solution. It explains how bindless descriptors provide more flexibility and improve CPU performance in rendering code. The article also mentions the performance implications of using bindless and the possibilities for moving to bindless in the future, such as texture atlases.
