As PlayStation continues to broaden its ecosystem across PC and mobile, they will face some of the same technological barriers that other companies have. A couple of the core challenges are creating a singular instance of user accounts and storing game saves across platforms.
On the console side, Xbox has led the way with the ability play games across PC and Xbox with your save being stored in the cloud. But while PlayStation is no doubt working towards that end, it could be some time before they reach the end goal.
PlayStation has introduced a new landing page describing their efforts to bring more of their first-party titles to PC. Within the FAQ, they spell out some of the features that will not be supported including cross-save and cross-buy.
If I already own the game on PS4 or PS5, do I need to purchase the game separately to play it on PC and vice versa?
Yes, the PC and console versions of PlayStation Studios games are different products. It is currently not possible to purchase the PC version of a title and then play it on a PS4 or PS5 console, or vice versa.
Can I transfer my save from the PS4 or PS5 version to the PC version?
It is currently not possible to transfer your save data from the PS4 or PS5 version to the PC version of a PlayStation Studios title, or vice versa.
This isn’t hugely surprising. PlayStation is still maneuvering into a new model and it will be some time before they support a fully connected ecosystem. That said, we hope they are working towards that end aggressively.
