Sorry, but there is some confusion on this. We use Sony Release Control which shares some functionality with other Sony products (SecuROM), but we do not use SecuROM for the DRM. Once the Sony Release Control check is passed, Release Control self-destructs, removing the Release Control wrapper and it is never used again. Game updates will not use Release Control because obviously the release date is passed. Additionally, installing the game and then any future game patch will also remove the Sony Release Control check and it will never run on your compute
