Hello Inquisitors !
I play with a friend in coop mode, and we encounter many lag and rollback in all map. In solo we can play without lag and with 60fps in full hd.
The lag appear in random coop match, and we have lag since we have the game bundle (Martyr+prophécy) in november 2019. All the patchs hadn't resolve this very frustrating problem. We are in the steam pc client, and with the fiber connection. I play another titles online as Diablo 3 or CS without any lag.
I dream this game in coop without lag and disconection :-)
