Not really helpful is it ?
Mockery ? This is a paying customer. Not impressed.
As for the OP..... clearly updating has created an issue that appears to be reducing performance.
As with any addon doing this, you are best to unistall the entire program, including SODE from Control Panel, then reboot.
Then reinstall SODE and then the latest GSX program.
I found that SODE had not been activated properly, so I reinstalled SODE from its devs site. So there could be numerous reasons why an update causes an apparent issue.
When I installed GSX, my airports were not recognising that SODE was installed correctly. So I uninstalled GSX, reinstalled SODE, then reinstalled GSX. After rebooting all was good.
It is annoying when a 50 GBP piece of software causes problems, and no advice is forthcoming.
Hope this helps.
(More advice - update to P3D .... better looking and performance, on the same hardware !)
Good luck my friend.
