Not necessarily, I think game is not leaking anything. It just streams a lot of stuff from SSD and that seems to cause hickups when it does so. This is especially apparent on Hogsmeade.
Castle runs mostly fine, but when you enter a new room or hall, it stutters for a bit, loads some stuff, and then it is fairly stable. This really calls for DirectStorage or a smarter texture streaming technique. But we know what happened with Forspoken when they did that, game simply streams super lowres textures when it is under VRAM pressure.
Sampler Feedback, RTXIO, DirectStorage, all kinds of stuff is there. I'm sure a decent compromise can be found for both RAM and VRAM starved systems for this game. It somehow runs on Series S, fairly good at that, 900p/60 FPS with decent graphics and 1080p/40 FPS if 900p is low for your tastes. I'm pretty sure this game uses a more advanced streaming technique on Series S to accomodate for the lower amount of budget. My guess would be that DirectStorage or some sorts. I cannot quite say for sure though. All I know is that if Series S does not show the similar stutters when going from hall to hall, then it means it simply uses a better streaming technique. There really is no possible way to fit all data in its memory budget.
I've seen this post but I wonder how common it is or an outlier. I ever see any kind of texture streaming in Hog Legacy on PC, it really tries to load high quality textures at all times, unlike Forspoken.
I like this idea, but a middle compromise can be welcome too. I'd prefer some slow texture loading here and there if it means that it will get rid of asset loading stutters.
