A recent post on Reddit (linked below) shows that GSX Pro is causing significant loading times in MSFS. Far more than other add-ons.
That's only because none of the "other add-ons" tested added a large number of new Simobjects in the sim. Had the test being made with something like FSTL, FsTraffic, or similar products with a large collection of models and liveries, they would show a similar impact on loading time as GSX.
I'd love to understand why this is the case and if there are any plans to reduce its impact on loading?
We have a paragraph in the manual that offer with a suggestion that will reduce the impact on loading time quite significantly, called
MSFS takes longer to start with GSX installed, at Page 97.
GSX needs to add a large number of available Simobjects to the simulator, with many models in hundreds of different liveries so, it’s normal it adds to the startup time, like any other product that needs to add a large collection of objects and texture, for example an AI Traffic package.
A way to reduce the startup time, is to Disable ALL “AirportServices” files, that is putting all the airports in the “AirportServices” list on the Config Page in the FSDT Installer, to the “Disabled” column.
This will speed up the startup time considerably, since those files cover about 15.000 airports. Disabling Airport Services will only result in less accurate Operator selection for Ground Vehicles servicing AI or wandering around the airport. Those will be selected “By region” instead of “By airport”, so the operators will be more generic.
GSX vehicles proper, used by your airplane, won’t be affected by this.
