Crusader Kings III on GeForce RTX 3090

Well above recommendedEstimate · medium confidence, ±20%

Yes. The GeForce RTX 3090 is well above Crusader Kings III's recommended spec. We estimate ~235 fps at 1080p high (range 188–282, medium confidence, ±20%), GPU-limited. At 1440p high expect ~165 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

NVIDIA RTX card: turn on DLSS in quality mode before dropping the preset; FSR and XeSS also work if the game lacks DLSS.

What limits performance

Estimates above: GPU-limited, assuming a processor fast enough not to hold the GeForce RTX 3090 back.
Processor needed for ~235 fps: Ryzen 9 7950X3D 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 235.
