The Sinking City 2 system requirements target Windows 11 x64, need a 70 GB install, and run on Unreal Engine 5 with an SSD strongly recommended. The exact minimum and recommended values for CPU, GPU, RAM, and DirectX level are listed on the Steam store page (AppID 2825860) and are the only authoritative source for those numbers. Treat any third-party "estimated" spec sheet as a community guess. Pre-purchase, the safest move is to compare your hardware against the live Steam page rather than against a screenshot.
