Their wording to me doesn't sound like just a BC patch but who knows
In April's
Community Care Package, we explained the graphic level we were targeting, the various technical issues we were experiencing, and the reason for the delay in development. As previously explained, PUBG: BATTLEGROUNDS on console platforms is very sensitive to memory usage. As a result, we've spent a lot of time optimizing memory usage on console, allowing us to add improved graphics options. Also, with the support from the platform holders, it became possible to differentiate between the previous generation (PlayStation®4/4 Slim/Pro, Xbox One/One S/One X) and the current generation consoles.
There is a potential stability issue in delivering the same level of graphics that many players expect on all console devices. Therefore, we've provided different maximum framerate and resolution options per console device to provide stable gameplay.
