This extension adds support for querying the amount of memory used and the
|
||
|
|
total memory budget for a memory heap.
|
||
|
|
The values returned by this query are implementation-dependent and can
|
||
|
|
depend on a variety of factors including operating system and system load.
|
||
|
|
|
||
|
|
The pname:heapBudget values can be used as a guideline for how much total
|
||
|
|
memory from each heap the process can use at any given time, before
|
||
|
|
allocations may start failing or causing performance degradation.
|
||
|
|
The values may change based on other activity in the system that is outside
|
||
|
|
the scope and control of the Vulkan implementation.
