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.
Upscaling & upscaler posture
The Sinking City 2 ships with NVIDIA DLSS 4 + DLSS Multi Frame Generation only on launch. There is no AMD FSR, no Intel XeSS, and no Unreal Engine 5 TSR upscaler toggle exposed at launch. AMD FSR support is planned but is blocked on AMD releasing the required UE 5.8 plugin/patch, so it is not yet available on the launch 1.0 build. The Steam Community General Discussions pinned launch FAQ for AppID 2825860 carries the official first-party answers for the post-launch FSR / DLSS Frame Generation / DLSS Upscaler / DualSense audio / stuck-in-collision cluster, and the five corresponding [/faq](/faq) entries (fsr-not-yet, dlss-fg-performance, dlss-missing-option, dualsense-audio-output, stuck-in-collision) are sourced from there.
