Expansion - Hearts of Iron IV: Arms Against Tyranny System Requirements

If your PC meets the *minimum* requirements (Intel Core i5-750 or AMD FX-4350, Nvidia GeForce GTX 470 or AMD HD 5850, 4 GB RAM), you should be able to run the game, but likely at lower settings and with potentially slower performance, especially during late-game scenarios with many units.

The *minimum* GPU requirement is an Nvidia GeForce GTX 470 (1.28 GB) or AMD HD 5850 (1 GB) or Intel Iris Xe G7. For a smoother experience at higher settings, an Nvidia GeForce GTX 570 (1.28 GB) or AMD HD 7970 (3 GB) or Intel Iris Xe G7 is *recommended*.

The game requires a *minimum* of 4 GB of RAM. However, 6 GB of RAM is *recommended* for better performance, especially with larger map sizes and more complex scenarios.

While the Intel Iris Xe G7 is listed as a *minimum* requirement, performance on integrated graphics can vary greatly depending on your specific CPU and settings. You may need to play at the lowest settings and a smaller resolution to achieve playable frame rates.

This depends on your hardware. Start with medium settings and adjust from there. If you experience lag, lower settings like shadows, water quality, and tree detail. Disabling V-Sync can also improve performance.
