Thanks
Well after that flight i mentioned I rolledback my Nvidia driver. And then had an absolutely flawless flight from Lisbon to London.
And it’s really tricky as there sre so many potrential sources for problems.
I have plenty of patience when it comes to analyzing and testing after 40 years as a developer but it’s hard to see progress as every plan following a logic path do not pay off and the “bug” never relieves itself.
I appreciate your suggestion to start with lowest possible graphics and so eliminate problems step by step so to say.
I’ll give my setup a few more chances as it actually CAN behave decent now and then.
