Grandpa's Legacy on Arc B580

Well above recommendedEstimate · low confidence, ±30%

Yes. The Arc B580 is well above Grandpa's Legacy's recommended spec. We estimate 300+ fps at 1080p high (range 283–300+, low confidence, ±30%), GPU-limited. At 1440p high expect ~283 fps, so every preset holds 60 fps. Its 12 GB of video memory covers the 1 GB the game requires at minimum. 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: ultra preset
60 fps at 1440p: ultra preset
144 fps at 1080p: ultra preset

Intel Arc card: use XeSS (native on Arc) or FSR in quality mode before dropping the preset. DLSS is not available.

What limits performance

Estimates above: GPU-limited, assuming a processor fast enough not to hold the Arc B580 back.
Processor needed for 300+ fps: Ryzen 5 5600X or faster (slowest current desktop CPU our model expects to keep up).

Video memory

Arc B580: 12 GB
Minimum spec: 1 GB (+11 GB headroom)
