Paradox date Stellaris 4.0, a "phoenix update" to attract new players and improve performance

I've got 700 hours in the game and I've finished 1 game. I usually get bored near the end when I'm either guaranteed to win or the performance starts chugging, or when I get bored of genociding the galaxy.

Yes

I finish them all the time. Yes, I have ADHD and often hyperfocus to the point of bodily harm when playing strategy games, but I'm sure that has nothing to do with it.

Cuz once you get the end game it starts lagging so bad no one can actually finish.
