Good day,
I have following problem: always, when I change something in the IXEG 737's FMC, which isn't executed yet, my FPS drop and I'my not able for many seconds to press EXEC.
It's okay for one fix change, but without pausing the sim (yes, your're able to click EXEC and stop the problem in pause mode), your're not able to change a complex STAR in the DEP/ARR page (not shown in the video), which makes this so perfect plane unflyable on IVAO.
For this test I removed all plugins.
Kind regards
Julius
