UPDATE: A quick update on backward compatibility – With all of the amazing
games in PS4’s catalog, we’ve devoted significant efforts to enable our
fans to play their favorites on PS5. 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.
In his presentation, Mark Cerny provided a snapshot into the Top 100
most-played PS4 titles, demonstrating how well our backward compatibility
efforts are going. We have already tested hundreds of titles and are
preparing to test thousands more as we move toward launch. We will provide
updates on backward compatibility, along with much more PS5 news, in the
months ahead. Stay tuned!

他們相信所有4000+的PS4遊戲都可以直接玩，只是他們從TOP 100款開始測試。
因為要每個遊戲都測試過，才知道有沒有問題，讓遊戲可以有更高或更穩定的FPS，看有
沒有需要找開發商調整。
已經測試了幾百款遊戲，準備繼續測試上千款。
之後提供更多向下相容+PS5的資訊。
