Ratchet & Clank: Rift Apart was famously among the first PlayStation 5 exclusives made by Sony's internal studios, specifically Insomniac Games.
The titular rifts (dimensional portals) were said to be heavily based on the PS5's SSD solution, to the point where it was stated that the game couldn't be done as-is without it. Creative Director Marcus Smith explained in June 2020:

That would not have been possible without the solid-state drive of the PlayStation 5. The SSD is screamingly fast. It allows us to build worlds and project players from one place to another in near instantaneous speeds. It is an unbelievable game-changer in terms of we can now do gameplay where you're in one world and the next moment you're in another.
We're loading up levels and that happens so quickly and in the action that you don't even imagine that this is something we couldn't do before, because it feels so natural. Long gone are loading screens. Now it's all about bringing exciting new adventures.
However, when Ratchet & Clank: Rift Apart finally landed on PC this past July, it didn't actually require an SSD (unlike, for instance, Bethesda's Starfield). Still, alongside a few weird issues like ray tracing being locked out of AMD graphics cards for some time, testing of the PC version showed that faster SSDs than the one available in Sony's PlayStation 5 would be slightly slower loading the game's portals (or rifts, if you prefer) than the console version.
It turns out there's a simple fix for that. Twitter user Moeez Malik discovered that simply removing the cache.pso file from the
