When I switch zone my ping shaking beetwen 10-1000 ms (every each day different times happening)

It usually happens during the time intervals when players are playing games

I have had the same problem with different internet providers in different cities for a few years.

There are many people in different parts of the world who have this problem with me.

Can you help me? I don't think it is related to my internet provider.

Lag comes from 1 of 3 sources:
- Player's ISP (you just said you don't think this is the issue)
- Player's hardware + graphics renderer
- Server lag (everyone in the game experiences this)

Try changing your graphics renderer to something else. Keep in mind that doing this will clear your cache and cause everything to load more slowly the first time you see it again.

DO NOT SELECT VULKAN IF YOU HAVE AN INTEGRATED GRAPHICS CARD. It will crash your game.
