My servers are generally low pop, but last week I had a spike in pop.

When my server hit 18 players, fps went from around 7000 to 1.

This was seen on Hashima, I tried to produce the issue again on my own map but never had more than 13pop so the issue was not noticed.

System is a Ryzen 9 7950X
My old window 2022 box handled the exact same server with 38pop and 20Q no problem on a Ryzen 7 5800x
