Hi i'm from france and i get some ping issue. I tried to connect from different line and computers (Office, home, friend home) and what ever connection used (adsl, cable) I got ping jumping from 150 to 600. It jump when an npc come next to me. can you fix it or give me a solution?

For exemple : I have a good gamer PC at home with 100mb optic cable connection and Xsyon is the only game where i have 600 ping when a revenant attack me... Then play LOL with LOL with 20 ping...
