Basis: there is no store page to read notices from; the depot worker has read 2 of its manifests, last on 10 Sep 2026. 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.
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.
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.
