problèmes de police de secours avec le calcul de la mémoire

So I deactivated streaming and I launched a memory calculation and it worked strangely, when the memory calculation is launched the result is displayed instantly, there is no loading the result is displayed directly and something else when I deactivated streaming it generated all the HLODs so my memory exploded and went up to 156,000 / 100,000 and I have a huge loss of FPS.
