I installed Starfield two days ago, and my other games no longer run. Star Trek Online goes through the launcher, and then gives the message:
"You will be unable to play using your current Video Card. Please upgrade your Video Card to one that supports DirectX Hardware Feature Level 10 or higher. See your Video Card manufacturer's documentation for information on DirectX Hardware Feature Level support."
Lord of the Rings Online simply disappears after the launcher.
I upgraded Adrenaline to 23.8.2 and they still won't run.
I have noticed I can no longer change screen resolution in Windows, and while the display is locked at 3840x2160, the only thing listed under "List All Modes" in Advanced Display Properties is "800 by 600, True Color (32 bit), 60 Hertz".
