I am not sure what it causes! When you arrive to world quest and you get freeze 1-2s and go back to normal on main. But, not on alts, like much less freeze or almost no freeze. How to solve this issue? Cant it be cache who collect all info on main coz you play main more than alts? Do I need to delete cache or someting like that else I dont know where it comes from! Thanks!
Those kind of issues are usually add-on related so I would try disable your add-ons and see if you still get the freeze without them.
As far as I’m aware, the game cache files are shared and not a per character thing. There’s no harm in deleting the cache folder to see if it makes a difference though. Deleting it won’t reset any settings.
