after MT 6 days ago, i play ryl very lag, delay 5-10 second , cant hit monster and cant do anything, before that time everything was good , my conection good, no RTO, ping 17ms
and then i use free vpn, trial 7 days , its only litle bit lag but when war lagging,
now i want ask what free vpn to play this game?

An optimized VPN section in the launcher will be added on the upcoming update. This feature is projected to improve the network stability & reduce the overall delay for Warfarians from all regions.

but when i played RDR & GTAV always smooth.
Thanks to you now i know it because VPN.
