Description: 

UPDATE: 
Confirmed by Atrayonis to be an OpenMW physics conflict with slaves colliding on slave market cage geometry, should be fixed in OpenMW nightly. (March 27, 2021)
Hemaris and Minerman60101 note that the lag spike may also be caused by the slave market itself, as disabling the holding doors, cell doors, and ex_t_root_04 reduced lag significantly due to collision calculations.

Screenshots are in TR discord(same username):

Near the Telvanni Council house in Port Telvannis, physics draw events/threads spike to 319 in the F3 overlay. This makes the area nearly unplayable, dropping to single digit frames. Disabling the mounted Dres guard and riverstriders does not appear to fix the issue. I'm not really sure what script/npc/object is causing it.

Does not appear to occur in other Telvanni towns like Tel Ouada or Llothanis.

Hemaris and Minerman60101 think that the lag spike may also be caused by the slave market itself, as disabling the holding doors, cell doors, and ex_t_root_04 reduced lag significantly due to collision calculations. I'm not sure if that changes anything, but I figured I'd document it here as well
