Yes, but I’ve already written in my opening post that I tried that mode, so I did not respond to your post. I’m sorry for that!
As an update, additional things I have done right now:
- Remove [old] drivers from my computer (including Realtek drivers)
- Took a look into the event monitoring. There are the errors 0xc0000005 and 0xc0000409 randomly thrown (means not on every attempt)
- Unplugged keyboard and mouse and replaced them with others
- Deactivated Windows Defender
- Freshly installed MS GameCenter and Xbox-App (hadn’t them before as I’m on Steam and the game ran fine without these apps)
- Deactivated game mode
- Written a support ticket… but expecting to wait long and get boilerplate-suggestions first
I should also mention, that I switched to the Asus RX6900XT recently, but already flew about 40 hours without problems…
I’ll try now to add a debugger to the executable file to see if I get any clue from it. Would be so nice to have sth like an info-log to see, at what loading point it got stuck. But what would be too easy.
