MSFS 2020 - GSX - Loading and Updating Times

[Hanse]

When GSX is installed it takes  2:16 minutes more to load the sim (5:20) than if GSX is not installed (3:04). Also I detected that the time to close the sim is much longer than without GSX installed. By the way to update GSX via the FSDT-Installer takes additionally more than 25 minutes on my system with a highspeed internet connection. Why this with GSX takes so long (compared to the programs) and is there a way to shorten those times?

2 minutes more is reasonable and not unlike any other similar package with lots of objects variations. The manual comes with a paragraph named MSFS takes longer to start with GSX installed at Page 97, which offers some suggestions.

And, the new Livery Manager added in version 3.5.7 can further reduce loading times by reducing the amount of installed objects variations due to the available operators. The chapter in the manual which explains how to use it, starts at Page 117.

Not sure what you mean with highspeed internet but, on a 1Gb/s it takes about 5 minutes for a full reinstall. Not possible to comment on update times, without knowing which version you were updating from.

It also depends if you use a LAN-cable or Wifi connection.
