Im not using the Geforce Experience Tool.

Yes, i guess its something special here on my PC but there is not a general problem, moree a combination of something.

Yesterday, after changing resolution down and up again, it worked for 3 missions.
When i continue my campaign in the evening, im going to start a scenario first to see what happens;
Then im going to try just to open and close the workshops only - see if it works.
Then im going to set the resolution down and up again... i want to encircle the problem.
