Description

This extension relaxes the maxStorageBufferRange limit, allowing more than 4GB to be accessed through a buffer binding (or through a buffer device address). It adds pipeline and shader creation flags that request 64-bit addressing support, and defines which addressing calculations use 64 bits of range.
