Hey guys!!
Well, I have read everything and would like to add my report:
First of all, I have the same issue in both 11.40 and 11.50 version. I have the latest 733 version installed btw!!
It happens only in flight whenever I have a major change to do into the CDU, dct routes, whatever requires the EXEC function. The fps drops to around 0.4 until I execute the change, then things go back to normal.
I have tried everything, windows defender, firewall, the are all deactivated. My notebook is a i5 7th, gforce 940mx 4gb and 8gb ram.
Thanks for your help!!
Best Regards!!
