Sorry @Torxen, I missed this. Thank you for uploading your launcher.log, everything looks as it should.
Admittedly, you’ve exhausted a lot of options, and I’m not sure what else to recommend. There will be some sort of niche driver or hardware compatibility issue, but it’s hard to know where to start.
The information in the logs does not point us in any direction unfortunately.
I’m happy to refund Vermintide 2 for you, if that’s an option you’d be interested in.
