This section lists the differences between each 10Level9 feature level and the D3D_FEATURE_LEVEL_11_0 and higher feature level for the ID3D11DeviceContext methods.
Only Texture2D and buffers may be copied within GPU-accessible memory. Texture3D cannot be copied from GPU-accessible memory to CPU-accessible memory. Any resource that has only D3D10_BIND_SHADER_RESOURCE cannot be copied from GPU-accessible memory to CPU-accessible memory. You can't copy mipmapped volume textures. ${REMOVE}$

Number of primitives may not exceed 1048575. Textures cannot repeat over one primitive more than 8192 times. Index values cannot exceed 1048575. Note: When you call the DrawIndexedInstanced method with a vertex shader that is bound to the pipeline and that doesn't import any per-instance data, some Direct3D 9 graphics hardware might not draw anything. In particular, if the vertex shader does not use any per-instance data, calling DrawIndexedInstanced with 1 instance is not equivalent to calling Draw.

D3D_FEATURE_LEVEL_9_3
Even though you specify float values to the members of the D3D11_VIEWPORT structure for the pViewports array in a call to ID3D11DeviceContext::RSSetViewports for feature levels 9_x, RSSetViewports uses DWORDs internally. Because of this behavior, when you use a negative top left corner for the viewport, the call to RSSetViewports for feature levels 9_x fails. This failure occurs because RSSetViewports for 9_x casts the floating point values into unsigned integers without validation, which results in integer overflow.
