I get weird input lag. It'll take several seconds of my inputs, then do them several seconds after I've inputted them. So when I see a monster, I'll try and swim away and dash, but it will force me to keep going in the direction I was swimming and input the dash several seconds after at seemingly random times.
This only seems to occur in multiplayer, and it happens at complete random, but pretty consistently ever minute. When I mess with the video settings, sometimes it will work better for a short period of time before getting worse again.
