Hi Litjan! Thank you for the contact. I noticed that this problem just happens when I enter or change the datas of the route on the FMS, during the flight. If I enter or change the datas on the ground, is possible to notice the Xplane becoming momentarily slowly (the frame rate increases and decreases) but returning to normal frame rate as soo as I finish the flight plan.
Do you have some suggestion to solve this problem?
Regards;
Guilherme
