Need help, so when playing co-op 2 player seems to be lagging when hitting. So instead of the flow of hitting, they would swing their weapon and before hitting the target swing their weapon again. This really breaks the flow of combat and not sure why it's doing this

1 player isn't lagging at all. Only 2 player.. We using a direct LAN cable. What seems to be the problem?

Is it The LAN cable we using? The Internet speed? The router? The game itself?

I haven't experienced anything like this on any other online games. So I'm not sure what's going on. Some help would be really appreciated

Also when 1 player logs out and 2 player becomes basically 1 player it runs smooth.. But when the previous 1 player joins he starts to lag until we go into a cave then it's back to 2 player having the lags

Edit: By LAN cable I mean the direct LAN cable plugged in from the router to the PS5. We using a 20M CAT6 LAN cable
