S.T.A.L.K.E.R.: Clear Sky — system requirements & benchmark status
This game is in the catalog, but no published review benchmarks have been collected for it yet — so this page carries no frame-rate numbers, no verdicts and no estimates. Below are the publisher's own system requirements and what they say about the hardware the game targets. A game joins the calculator only when published review benchmarks cover both its CPU and GPU sides.

Hardware demand level
Low — estimated from the graphics card named in the recommended requirements above (integrated graphics). The demand level classifies the publisher's published requirements only; it is not a benchmark result and predicts no frame rate.
Benchmark status
Not yet measured. Bottleneck Verdict adds a game to the calculator when published review benchmarks cover both sides at the game's highest settings, native resolution, no upscaling — the same bar the measured games met. Until then this page claims no performance figures for S.T.A.L.K.E.R.: Clear Sky.
