We saw quite a few people logging in with 100+ FPS and then declining to perhaps 30-40 over an hour or more. We think we will be able to prevent the decline by upgrading engine versions to 4.23 (we're on 4.21 right now).
So the engine upgrade is in the works for this month, or January at the latest.
I put the timing that way, because the coders asked me to take it easy on promises for dates during the Holidays.
