Ever wondered how many resources you can bind to a shader at one time? Or how many slices you can store in a 2D texture array? All of these limits can be found in the D3D header. For D3D11, this is D3D11.h. In this post, I'd like to point out notable improvements in D3D11.
Input assembler binding points (D3D11_IA_VERTEX_INPUT_RESOURCE_SLOT_COUNT): 32, up from 16
Maximum number of layers in a 1D or 2D texture array (D3D11_REQ_TEXTURE2D_ARRAY_AXIS_DIMENSION): 2048, up from 512
Maximum number of interstage float4s: 32 between every stage, up from 16
Maximum size 1D texture (D3D11_REQ_TEXTURE1D_U_DIMENSION): 16384 texels, up from 8192
Maximum size 2D texture (D3D11_REQ_TEXTURE2D_U_OR_V_DIMENSION): 16384x16384 texels, up from 8192x8192
Maximum number of unordered buffers that can be bound to a pixel or compute shader (D3D11_PS_CS_UAV_REGISTER_COUNT): 8, up from 0 ;)
