Crusader Kings III on Radeon RX 6900 XT

Well above recommendedEstimate · medium confidence, ±20%

Yes. The Radeon RX 6900 XT is well above Crusader Kings III's recommended spec. We estimate ~250 fps at 1080p high (range 200–300, medium confidence, ±20%), GPU-limited. At 1440p high expect ~175 fps, so every preset holds 60 fps. Model estimate, not measured; data updated 2026-09-24.

Estimate · medium confidence, ±20%

Estimated FPS from our model (v0), based on the game's published requirements and relative GPU/CPU performance. Not measured. Real results vary with drivers, patches, and scenes. Values above 300 fps show as 300+. Data updated 2026-09-24.

Best settings

60 fps at 1080p: ultra preset
60 fps at 1440p: ultra preset
144 fps at 1080p: ultra preset

AMD card: use FSR in quality mode before dropping the preset (XeSS also works). DLSS is not available on Radeon.

What limits performance

Estimates above: GPU-limited, assuming a processor fast enough not to hold the Radeon RX 6900 XT back.
Processor needed for ~250 fps: Ryzen 9 9900X3D or faster (slowest current desktop CPU our model expects to keep up).
With the recommended CPU (Core i5-8400): CPU-limited at 1080p high: about 90 fps instead of 250.

Video memory

Radeon RX 6900 XT: 16 GB
The publisher lists no video memory requirement.
