Like many others, i have problems with the aircrafts FMC. When entering SIDS and STARS, cost index, crz alltitude etc. Xplane freezes for 5-20 seconds. I could live with but the biggest issue is when making a directs or even changes (only after take off) in the aircraft FMC because my framerate litterallly goes down to 0.125fps or less! I've read countless pages on this forum trying to fix the issue, many manages to fix the issue by either turning off windows defender or just make an exception. I have done that to both Windows defender and Malware Bytes. But it still doesn't work.
