Setting Ground Aircraft Density causes stuttering


I was trying to find out what was causing stuttering as I fly closer and towards airports. I’ve always had the ground aircraft density set to a value and always had stutters. Finally I thought of setting this to 0 and this seems to remove the stuttering (for now at least). I would have thought that these are static aircraft and therefore shouldn’t cause stuttering but seems like I was wrong.

Now my airports are ghost airports, no aircraft in it.

Anyone faced a similar situation?
