I have also noticed a large increase in the amount of time sparta takes to respond - both in game app and in browser version (I use both chrome and edge)
This is especially noticeable when doing tasks in Pans - for eg taking orich - from pressing 'upgrade' button to upgrade happening takes 20 seconds
Also since todays update in app, I find I start app and logon and consistently get a black screen. I have to close app and restart, when app then works.
I too have quite a high spec PC
