If they disable this texture streaming blocking feature, then they should at least make it work first.
Because people have problems with not loaded textures, even though there is a large amount of video memory available.
The statement that switching some option that was intentionally added to the game will lead to a crash - sounds very strange.
Usually, a lack of memory in normal engines leads to freezes, not crashes. Otherwise, video cards with small memory would not be viable.
Do you think that when video memory runs out drivers says: - " I can't, ... error." ?
(and my previous edit - is just name another broken option in this game )
