So first few weeks i had constant 30-40 ms (latency) ... Now past couple days its been constantly going up and down from 100 to nearly 2000 and remaining there for hours and hours, during this high latency numbers iv checked with other game servers and generally my network performance, everything is smooth under 40ms ... Please any explanation what is going on, because i found out that very little amount of players have this issue.
I would recommend that you check your internet service provider. It sounds silly but 9/10 its usually them screwing with you. Also check yer firewall, scan EVERYTHING and hope that warmane contact you.
