Sony has begun rolling out a number of patches for PS4 games (assumed to be in preparation for PS5), but the games are seeing huge improvements on PS4 as well.
The Last Of Us Remastered in particular has seen a huge improvement when it comes to load times on PS4 with it taking only 14 seconds to load into a new game with the 1.11 patch. For comparison, it took 1 minute 30 seconds before the patch was installed.
Similarly, loading from a save also took around 14 seconds whilst it took roughly two minutes before the patch. You can see the comparison in the below video.
It’s unclear how there’s been such a drastic load time jump without the use of a fast HDD, but obviously some serious optimisation has been done.
