This is what Cerny said:
This time around and some game code just can't handle it testing has to be done on the title by title basis results are excellent though we recently took a look at the top hundred PlayStation 4 titles as ranked by play time and we're expecting almost all of them to be playable at launch.

And this is what the PS blog said:
We believe that the overwhelming majority of the 4,000+ PS4 titles will be playable on PS5.
We're expecting backward compatible titles will run at a boosted frequency on PS5 so that they can benefit from higher or more stable frame rates and potentially higher resolutions. We're currently evaluating games on a title-by-title basis to spot any issues that need adjustment from the original software developers.
This sounds to me that almost all games will run the same as they run on PS4. And on a title by title basis there will be some games that have boosted frequency, but if all of them would have the boosted FPS and RES they would say it and not just say "playable" on PS5.

Please show me right now where they said that all games that have been released after July will run boosted.
