thread-safe, and resources may be completely loaded in the background.

stated in relation to this flag.

Thread support for background resource preparation. This means that resource
107

data can streamed into memory in the background, but the final resource
108

construction (including RenderSystem dependencies) is still done in the primary
109

thread. Has a lower synchronisation primitive overhead than full threading
110

while still allowing the major blocking aspects of resource management (I/O)
111

to be done in the background.
