Defragmenting GPU memory</h1>
<p>It is also possible to defragment allocations created in memory types that are not <code>HOST_VISIBLE</code>. To do that, you need to pass a command buffer that meets requirements as described in <a class="el" href="struct_vma_defragmentation_info2.html#a7f71f39590c5316771493d2333f9c1bd" title="Optional.
