???I specifically mentioned the speedy on rails parts and you said " no dude" and showed that image above. then turn around and say im going back to the on rails part I specifically mentioned in my other post?
Anyway yes, they are using tricks, they have enough space to preload at least one area.
on the NON ON RAILS rifts where you only go through one rift at a time that rift area is already preloaded in memory when you get to it. Fast loading from using a SSD for sure... but IT IS NOT INSTANT LOADING.
On the on rails parts they can preload one at a time and use an animated texture during the transition to mask any inconsistencies ( probably from the speed of movement) .... IT IS NOT INSTANT LOADING.
