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.
