I figured out what was causing the rest of the lag: removing every Push Volume in the map (there’s 34) brought it back to the usual ~160 fps I had prior to 0.18.1.1.

These were all in the map prior to that update, so I assume something about the update un-optimized push volumes somehow. This is the only push volume-related patch note from that update though:
