If you thought Final Fantasy VII Remake look splendid on the PS4/PS4 Pro (except for those damn textures), then you ain’t seen nothing until you see the PS5 version running.

60fps action combined with improved lighting along with vastily improved textures really help showcase the effort that Square Enix puts into their RPGs when it comes to high fidelity graphics.

So how’d they do it? They revealed in a recent Unreal Engine blog all the tricks they used to optimize the game on the PS5.

With PS5 having an SSD, I/O speeds were no longer a bottleneck. Instead, time slicing and CPU load became the causes for longer load times.

Because of that, we improved the load flow by doing things like putting in unique serialization so that it would lessen the load during deserialization in areas especially prone to bottlenecks. Through these efforts, we were able to go from approximately 12 second load times down to six.

While we were exploring options for further improvement, we realized the loader was inefficient. So, we integrated Unversioned Property Serialization and IOStore, which were introduced with Unreal Engine 4.25. This title was developed based on UE 4.18, so it required some changes, but because of the implementations, we were able to shorten the time to about two seconds, so I feel that this brought improvement that was well worth the investment.

Even though the PS4 version of FF7Remake had an install disc, Square Enix still had to ‘forgo’ high-resolution textures due to the disc capacity on the PS4. But even with the new, Ultra Blu-Ray disc of the PS5, Square Enix found a solution: KRAKEN!

In the PlayStation 4 version, we had to forgo using a higher-quality format and high-resolution textures due to memory and disc capacity restrictions. However, we still didn’t have enough disc capacity with FINAL FANTASY VII REMAKE INTERGRADE to include a high-quality format and high-resolution textures.

And so, we integrated Oodle Texture [Compression], and by using it in combination with Oodle Kraken, we were able to achieve a smaller file size on the PS5 version, even taking the higher resolution textures into account.

Plus, the increased memory compared to PS4 and the improvement of the Non Streamable Mip Map, which ties into the response of the aforementioned question, also helped to load textures.

We were also able to use more high-resolution light maps, which improved the accuracy of the lighting.

The PS4 version of the game comes with the free upgrade to Intergrade, so if you don’t want to spend the extra money upgrading to the PS5 version with the Yuffie DLC, that’s one way you can see the differences between the PS4 and PS5 versions.
