+Descriptor Range Version 1.0
+''''''''''''''''''''''''''''
+The Version 1.0 ``DescriptorRange_V1_0`` provides basic descriptor range definition:
+
+#. **RangeType**: Type of descriptors (CBV, SRV, UAV, or Sampler)
+#. **NumDescriptors**: Number of descriptors in the range
+#. **BaseShaderRegister**: First shader register in the range
+#. **RegisterSpace**: Register space for the range
+#. **OffsetInDescriptorsFromTableStart**: Offset from the descriptor heap start
+
+Descriptor Range Version 1.1
+''''''''''''''''''''''''''''
+The Version 1.1 DescriptorRange_V1_1 extends the base structure with performance optimization flags.
+
+#. **Flags**: Provide additional information about the descriptors and enable further driver optimizations.
