What this means
Steam's minimum list is the lowest hardware the publisher says the game supports. The recommended list is what the publisher suggests for a better experience. Neither list says which settings, resolution or frame rate it targets unless the publisher's notes say so. Where a line lists two parts (for example an NVIDIA or an AMD card), the publisher treats either as meeting that tier.
