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!
重点是更新的这段，似乎之前的文章让人误以为发售只支援TOP 100款游戏，造成讨论。
他们相信所有4000+的PS4游戏都可以直接玩，只是他们从TOP 100款开始测试。
因为要每个游戏都测试过，才知道有没有问题，让游戏可以有更高或更稳定的FPS，看有
没有需要找开发商调整。
已经测试了几百款游戏，准备继续测试上千款。
之后提供更多向下相容+PS5的资讯。
