so finally i got a response on my ticket. They said do a latency test( type /latencytest in chat while in the game, takes about 10mins) So i did. And then i send the file(wich is not stored in the location it said it would be stored, but that is a different problem) And then they just say well yeah its probably in your connection.
So my connection is the same as it was when i had no lag problems(back in 2017), my provider is the same, my pc is the same, i got no mallware or crap like that. I checked what was connected to my router, only 3 android phones and my pc so not overloaded. Offcourse i have a wired connection and not wifi(who plays games on wifi??)
might also be worth saying i only have problems in this game, no other games have connection problems...
this is the exact reply i got on my latencytest file
