You can keep buying PlayStation 4 games without a second thought because you can enjoy them on the PS5. Sony devoted a good part of its presentation of March 18 to the backward compatibility between these two generations of PlayStation.
Sony's future console will be able to run all PS4 games on paper. If they are optimized for PS4 Pro, they will run as on the latter, otherwise, the services will be the same as on PS4. Unless, of course, the developers decide to make major improvements to their titles so that they can take full advantage of the power of the components of the PlayStation 5.
No question of having degraded quality or low-level emulation. Mark Cerny, the Sony system architect, was very clear: all the tests carried out so far on a very large panel of games (the Top 100 of best sales of PS4 titles) are excellent.
However, you have to make sure that all games support their new execution environment and that adjustments can possibly be made by their creator.
For the moment, no list of games can be established. It will be consistent, Sony promises and it will evolve over the months, after the release of the console. So if your favorite game is not backward compatible on Day 1, it will surely be backwards, especially if it is an AAA or a highly successful online title.
Backwards compatibility: it's already there and won't budge
Mark Cerny explained that several avenues were considered to make backward compatibility as effective as possible. The teams even thought of redoing what they had done on certain models of PS3: reinstalling a micro-PS2 on the motherboard of the console to run the games. Problem, it's very expensive.
In the case of the PS4 and PS5, the technical components are of AMD invoice. They have a common operating base and that makes things much easier. ” Once backward compatibility is implemented in our PS5 console, it's for good Assures Mark Cerny. It is enough simply to implant software routines and / or precise hardware elements in the operating system as well as the new components specially designed for the PS5 so that they reproduce the behavior of the chips of the PS4 without the least difficulty.
