More advanced features such as new shader models and rendering stages are only exposed on up-level hardware, however the hardware is not required to support all of these feature levels and the Direct3D runtime will make the necessary translations.įeature levels allow developers to unify the rendering pipeline and use a single version of the API on both newer and older hardware, taking advantage of performance and usability improvements in the newer runtime. Some feature levels include previously optional hardware features which are promoted to a mandatory status with new revisions of the API to better expose newer hardware.
The levels are grouped in strict supersets of each other, so each higher level includes all features required on every lower level. Feature levels encapsulate hardware-specific capabilities that exist on top of common mandatory requirements and features in a particular version of the API.
