Project Zomboid on Radeon RX 6400

Meets minimumEstimate · low confidence, ±30%

Yes, at lower settings. The Radeon RX 6400 meets Project Zomboid's minimum spec but not the recommended one. We estimate ~32 fps at 1080p high (range 22–41, low confidence, ±30%), GPU-limited. 60 fps at 1080p is out of reach. Its 4 GB of video memory covers the 4 GB the game requires at minimum. The cheapest current card for 60 fps at 1080p high is the Radeon RX 5600 XT (~68 fps). Model estimate, not measured; data updated 2026-09-24.

Estimate · low confidence, ±30%

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: not reachable
60 fps at 1440p: not reachable
144 fps at 1080p: not reachable

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 6400 back.
Processor needed for ~32 fps: Core i3-9100F or faster (slowest current desktop CPU our model expects to keep up).

Video memory

Radeon RX 6400: 4 GB
Minimum spec: 4 GB (+0 GB headroom)
