List of games that support Auto HDR
From PCGamingWiki, the wiki about fixing PC games
Auto HDR has been added to Windows 10 (Insider build 21337) and Windows 11. This feature adds HDR to games that didn't support it in the past.
In its Microsoft Announcement, they stated 1000+ titles where it is supported. This will be a work in progress list to log supported titles.
NOTE: Games needs to be launched at least once before Auto HDR is activated, and some crash at or just after start with HDR enabled under some configurations requiring hdr to be turned off or the title being started windowed first (GTAV for instance).
