Thanks for sharing your experience. This is not the first time that I have heard of the native weather radar causing performance issues after a long flight. It seems this only affects a small number of users, and we haven't been able to determine the cause, except that it has something to do with the native weather radar display. Troubleshooting has been slow going, since I've never been able to reproduce this on a computer that I have access to. We found some BIOS settings or graphics driver changes that may have made a difference in the past, but nothing was definitive. Unfortunately, without anything definitive, it's difficult for me to approach Asobo with something for them to look into. If you feel like you're seeing this very consistently, and you're willing to help, I might be able to devise some tests for you to run (editing the weather radar code), but I will warn you that a lot of good men have lost a lot of hours trying to track this one down. Thanks again, and I hope you are otherwise enjoying the aircraft! Let me know if there is ever anything I can do for you.
