Category names are Valve’s (Unknown, Unsupported, Playable, Verified). Each change is joined to the newest public-branch build in the seven days before it; no build is inferred. Verdicts before 3 Sep 2026 are not claimed. Data by SteamPeaks.com.
Basis: the store page was read on 5 Sep 2026; the account does not own this game, so its files have not been read and no anti-cheat, launcher or online service can be detected from them. Store notices have been polled since 3 Sep 2026, so a row with no dated change was already on the page then. Kernel-level is a property of the product (the table and its sources); a missing row means not detected, never none. Data by SteamPeaks.com.
Survey Aug 2026 · 87.0% of the survey’s graphics-card list is mapped to a tier, so the unmapped tail is visible rather than counted as failing · computed 8 Sep 2026 · how this is computed.
Source: Valve’s Steam Hardware & Software Survey, Aug 2026 (1 month on file). The survey is opt-in and skews toward recent hardware, so every share is an estimate of the surveyed population, not of all Steam users. Shares by SteamPeaks.com from the survey and its own GPU tier table.
