Installing Fallout 4 broke other games



  • I received Fallout 4 for Christmas and installed it through Steam. I fired it up and found I'm getting

    Game FPS Engine
    Fallout 4 (Steam) 7-9 Creation
    Subnautica (via Epic Games Launcher) 4-5 Unity
    AC Odyssey (Steam through UbiSoft Connect) 60 AnvilNext 2.0
    Portal 2 (Steam) 60 Source
    Elder Scrolls V: Skyrim (Steam) 7 Creation Engine
    Stellaris (Steam) 55-60 Clausewitz
    Kerbal Space Program (Steam) ~5 Unity Engine
    No Man's Sky (Steam) 60 Modified Unity

    My first thought was an engine problem, since it is affecting both Fallout and Skyrim and they're both on the Creation Engine but Subnautica and KSP are on Unity, so that doesn't explain it. It FEELS like a library problem, like the install of Fallout overlaid a (possibly older) copy of something on top of the current version? Is there something that is used by both Unity and Creation that could account for this kind of behavior? Or maybe it configured the OS to use... something it shouldn't be using?

    So far I have:

    • checked Windows Updates (I'm up to date)
    • updated video drivers (Nvidia GeForce RTX 3080 - 30.0.14.9729)
    • uninstalled and reinstalled all copies of MS Visual C++ (2008, 2010, 2012, 2013, 2015-2022)
    • checked for updated dll's by file modification date of the Fallout 4 install: none
    • checked for all updated files by file modification date of the Fallout 4 install: umpteen, but none seem like likely candidates (I can get the list if someone thinks it might be useful)
    • uninstalled Fallout 4, Subnautica still broken
    • reinstalled Subnautica both with and without Fallout 4, still broken
    • cranked all in-game (FO4) video setting to the very minimum, although given the strength of the box and video card, it should be playable at high everything

    I have noticed that, in FO4, if I am indoors and looking at the ground, I can get as high as 25-30 FPS. But if I step outdoors and look at... anything, I'm back to 4-5.

    Any thoughts or suggestions?

  • Follow-up: I gave up and punted. After trying upgrading to Windows 11, reinstalling DirectX 12, multiple version of drivers and validating OpenGL, none of which helped, I backed everything up and reinstalled Windows from scratch. This seems to have done the trick. Thank you to everyone! I really appreciate your suggestions. Plus now I know a lot more for next time. Yay?

    And to anyone having the same issue who came here looking for help, sorry.
