What the tiers mean

The minimum tier is the entry threshold, not a promise of high settings. The recommended tier is more future-appropriate for an Early Access game whose world and systems may expand. A 50 GB install allowance should remain free after OS updates and shader caches.

Laptop checklist

Compare the exact laptop GPU name, not just the series. Confirm the screen supports the desired resolution, use a power profile that prevents CPU throttling, and check whether the discrete GPU is selected for the game. A 6GB video card at minimum should have enough VRAM for the listed threshold.

Steam Deck status

No Steam Deck verification verdict was present in the captured Steam Appdetails response. Do not claim verified, playable, or unsupported status without a current store label or hands-on test.

Performance evidence boundary

These are official store requirements, not in-house frame-rate results. Once tested, record the game version, resolution, settings, driver, CPU, GPU, and average and 1% low frame rates. Until then, use the official tiers only.

Direct answer

Steam's minimum tier starts with an i5-8400 or Ryzen 5 2600, 12 GB RAM, and a GTX 1660 or RX 5500 XT. The recommended tier uses 16 GB RAM and an RTX 3070 or RX 6700 XT.
