Boost mode happens naturally as a result of playing on the PS5 but this boost cannot be handled by certain games due to their code which is why they need to be tested and tweaked individually to ensure boost mode works but results have been "excellent".
Rest of the PS4 games will run through legacy mode (essentially the same as it is on the PS4).

好像目前是100款PS4游戏可以以增强模式在PS5里游玩，剩下游戏的不支持增强模式，运行在PS5跟原来的PS4一样。

希望血源能进第一批支持增强模式的列表。

读盘还是很有区别的, 但是画面没区别了, 该丢帧一样丢帧, 因为运行在legacy mode

Lastly, we’re excited to confirm that the backwards compatibility features are working well. We recently took a look at the top 100 PS4 titles as ranked by play time, and we’re expecting almost all of them to be playable at launch on PS5. With more than 4000 games published on PS4, we will continue the testing process and expand backwards compatibility coverage over time.

说的很含糊，到底是100款列表里的游戏支持Boost Mode还是支持Legacy Mode，屎一样的PR。
