Crusader Kings III: All Under Heaven System Requirements

If your PC meets the minimum requirements (Intel Core i5-4670K/AMD Ryzen 5 2400G, Nvidia GeForce GTX 660/AMD Radeon HD 7870/Intel Arc A380, 8GB RAM), you should be able to run the game at lower settings. Expect lower framerates and potentially longer loading times.

At a minimum, you'll need an Nvidia GeForce GTX 660, an AMD Radeon HD 7870, or an Intel Arc A380. For a smoother experience at higher settings, an Nvidia GeForce GTX 1650 or an AMD Radeon R9 390X is recommended.

The game requires at least 8 GB of RAM to run. However, 16 GB of RAM is recommended for optimal performance, especially with larger empires and later game stages.

While the Intel Arc A380 is listed as a minimum requirement, running on other integrated graphics solutions is not officially supported. Performance will likely be poor, even at the lowest settings. A dedicated graphics card is highly recommended.

If you meet the recommended specs, you can likely play on medium to high settings. If you're closer to the minimum specs, start with low settings and gradually increase them until you find a balance between visual quality and performance. Experiment with disabling anti-aliasing and lowering shadow quality for a performance boost.
