The maximum number of outstanding asynchronous texture uploads allowed to be pending in Metal. After the limit is reached the next upload will wait for all outstanding operations to complete and purge the waiting free-lists in order to reduce peak memory consumption. Defaults to 0 (infinite), set to a value > 0 limit the number.
Usage
rhi.Metal.MaxOutstandingAsyncTexUploads [value]
Set via the console (~) or in DefaultEngine.ini / DefaultGame.ini.
