Ok, seems like I fucked up big time.
First of all: my hardware button for switching the gpus doesn't seem to work anymore, so you were right, of course with the radeon it's a different error message.
Second: I tried to manually install the latest intel driver, after that (and while starting Avorion) my pc crashed with a bluescreen. So I reinstalled the driver I had, when I originally posted the question. Started Avorion. Bluescreen.
But, the good news is: I have clientlogs of all these. :D Have fun with them, probably I'm just too silly to install a proper driver...
Hm, seems like they just crashed together with my pc. They're mostly just this:
