Depends on location (due to LODs and weird optimisation of the game).
Varies from 250+ to even 10+ in condos (250+ only if there's nothing in front of me besides flat grass), started to drop to 140-60 fps in my condo when there were many canvases placed and players joined. Worst fps drops are at others' condos (and it's not only caused by canvases, I've seen someone placed like 10+ bookshelves and filled them with many single books, they could drop me drastically).
In gameworlds, I've never experienced any drops during gameworlds on my current PC in usage. Mostly in ballrace, it usually stays above 100 fps, with periods where I can reach 200 fps.
