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 2026-09-25.

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 550 back.
Processor needed for ~210 fps: Core i3-9100F or faster (slowest current desktop CPU our model expects to keep up).
With the recommended CPU: CPU-limited at 1080p high: about 90 fps instead of 210.

Video memory

Radeon RX 550: 4 GB
