Hello everyone. I have the aerosoft a330 with Prepar3D v4.5.xxx (i don't remember the exact numbers in the xxx). I am having some fps issues with that plane only. In the other threads and forums they say it can be caused by the EFB tries to contact with Navigraph or something like that. But i don't use Navigraph charts on EFB even didn't logged in Navigraph via A3xx configurator. Is there any ways to simply disable the EFB? Or at least disable the EFB and Navigraph connection? They posted a file for EFB fix but this is for p3dv5 and for users who use Navigraph Charts so i am not sure will it work for me..

It is likely that if you have not selected Navigraph in the A3xx Configurator, then the problem is not the EFB trying to connect with Navigraph.

When you look at the A3xx Configurator, EFB settings tab, does it tell you that you are logged in to either NavDataPro or Navigraph? 

In the A3xx Configurator, General tab,

• Is your data source set to NavDataPro or Navigraph?
• Any checkmarks on Logging?
• Is "Force ECAM Software Rendering checked?
• Is "Webserver" in the MCDU section checked?
• What happens if you reduce either the amount of Max Airports, Max NDBs Max VORs, or Max Waypoints?

I have checked/done what you said and made a test flight. FPS is still very low, there's no problem when i fly manually, but when i engage the autopilot, and when the fps drops below 20, the elevators make the aircraft move up and down so rapidly

Does this elevator problem happen after you calibrate your controller?

How can i calibrate? Actually i use mouse yoke and keyboard only. And in that case, the elevator problem happens only when the fps drops below 20 while flying with autopilot, but while flying manually even though the fps drops below 20 there's no problem with elevators.
