Having the same issue here im using a keyboard that has a joystick which is configured for wasd but anytime u press w+d for example the character will continue walking in that direction , as the other guy said its impossible for small movements, impossible to drive. I tried going around the issue by setting the bind action to hold as i thought perhaps i had stick drift and it was the cause of the issue , as i was doing this i found another issue , as you go to set the bind “action prefix “ there is no way to save it. The available options read “cancel”, “reset to default “,unbind action”, “delete bind” no option to save. Ive contacted azeron support as i thought i was faulty hardware but everything checked out fine so came to the conclusion it must be an in game bug.?

If you don't have the same issue with other games, then it has to be a bug. Personally this is the only PS5 game for me, that supports MnK and has this bug.

I've tried different USB ports, because some people say you need to use front, some say use back. And my keyboard is generic and doesn't require software or updating.

Yeahh ive tried different games and it works perfectly must be an in game bug wonder if they’ll fix it

Alright, look at this. This is me pressing W and A, then W and D. I can reproduce it very consistently.

i have the same issue on ps5 with m&k only on arma reforger every other game i tested is working fine is nearly impossible to drive fly or win a gunfight and is really frustrating to die from that bug maybe you guys can't reproduce the bug but is definitely there and is destroying our experience in the game please look more into it

Thank you.
There are going to be changes in the next update which can potentially fix this. However we oficially do not support mouse and keyboard for playstation.
