Not yet measured
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.

As published by the publisher on Steam (checked 4 November 2026). Requirements are the publisher's target figures, not measurements — they describe the hardware the developer aims at, not the frame rate any part delivers.
| Component | Minimum (Steam) |
|---|---|
| Minimum | Windows 2000/XP, 1.2GHz Intel Pentium 4 or AMD Athlon processor or equivalent, 256MB RAM, 64 MB Video Card w/ Hardware T&L (GeForce 2/Radeon 7500 or better) DirectX7 compatible sound card, 1.7GB of free hard drive space, DirectX9.0c (included) |
| Recommended | Windows 2000/XP, 1.8GHz Intel Pentium 4 or AMD Athlon processor or equivalent/better, 512 MB RAM, 128 MB Video Card w/ DirectX 8 support (pixel and vertex shaders), DirectX7 compatible sound card, 1.7GB of free hard drive space, DirectX9.0c (included) |
Low — estimated from the graphics card named in the minimum 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.
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 Sid Meier's Civilization IV.
