I've deleted the .ini file and removed also all addon.
Just checked the game, still the issue.
However, i've found that some setting were available even after deleting the file so maybe the server keep track of old setting somewhere.
Can you please do the test on your side and see if characters vanish like in the video?
thanks.
You're probably in a sub-zone (for lack of a better word) boundary. I've had it happen in odd locations where if I take a step a node or a chest disappears and take another step it reappears. Those are the areas within a zone that the megaserver uses for load balancing.
Normally you wouldn't notice those but occasionally in a busy place you will. Sometimes you even get a loading screen for a fraction of a second when you cross one.
It's just a funky megaserver thing and nothing to do with graphic settings.
