GHOSTMD: aftrer updating to 5.01 from 4.04 W3 onyl launches into Blackscreen
no it does not crash at all, i can hear it running and i even can load the savegame
so the game DOES run
Delete
Documents\The Witcher 3\dx12user.settings (better yet, rename, to keep for later). Let the game revert to the defaults.
After it's re-generated when the game runs, look what's inside that file under
[Viewport]. Change the
Resolution= to something small and set
FullScreenMode=0 temporarily. It should at least run like that.
What do you mean by "updated?" It'd be better to install from scratch (and uninstall any previous versions). Also delete the settings entirely (warning: first copy your saved games from
Documents\The Witcher 3\gamesaves to some safe place).
Actually, what you're describing sounds like it could be caused by a DLL leftover in
bin\x64_dx12 from some outdated mod. Something like
dinput.dll,
dwmapi.dll,
version.dll shouldn't be there: if it is, it's just a loader for something else. But there are many possibilities what the name can be, it'd take forever to list them all.
Do other games work? I don't think you need to reinstall Windows then. Maybe re-install the game after uninstalling it first completely though. But for starters try the above less drastic measures. And remember to
protect your saved games.
