}

[−] Expand description

Specialization constant for pipelines.

Specialization constants allow for easy configuration of multiple similar pipelines. For example, there may be a boolean exposed to the shader that switches the specularity on/off provided via a specialization constant. That would produce separate PSO's for the "on" and "off" states but they share most of the internal stuff and are fast to produce. More importantly, they are fast to execute, since the driver can optimize out the branch on that other PSO creation.
