Ok you guys don't seem to be getting it, so after this post we can agree to disagree but it's clear some of you don't understand how this works. This post is for you.
STEP !:
When you have a PS5 disc that Bluray disc only works for the PS5. It won't install on an Xbox, that's because of software in the disc that's made specifically for the PlayStation. We clear?
STEP 2:
When you install your PS5 disc to a SSD, it downloads the game files, AND the proprietary software to the storage. Because the Install requires a PS5 to run. If you move that same install to an Xbox SSD, it won't boot.
STEP 3:
Now that all that is cleared up, here's the part that's hanging up everyone in the thread. So pay attention now, when you make machine specific software inside a BR disc, it has to keep in mind the size and TYPE of BR disc that the software is being installed in. Ok we good?
STEP 4:
Because of Step 4, when you install the game to your SSD drive, that install had the same limitations outside the disc as on the disc.
STEP 5:
Finally, because of Step 4, when you have a fast SSD drive, the game will not take advantage of those load times because the installed data has a cap. SSD drives have much fasters speeds than Bluray. This means that even with a SSD, the game you installed will only run as fast as what the limit on the disc was.
So what I am getting at is that it's useless to use the Bluray format for the PS5 if you can't even take advantage of the SSD.
That's all I'm saying.
Hopefully that finally clears everything up.
