[PATCH 0/1] MR5146: d3dcompiler: Enable semantic naming mapping in compatibility mode.

[Nikolay Sivov (＠nsivov)]

This was implemented in vkd3d 1.10. Another known feature that has to be enabled with compatibility flag is d3d9 style sampling functions. We currently don't do that, making them supported unconditionally.
