[2020] Serious problem

I'd highly advise you to check out the minimum specs of Dead by Daylight. They are there for a reason, as some system won't work it.

Your PC is your responsibility, espeically if you decide to pay an online game, as harsh as this sounds, but this is a multiplayer game. It's not just you playing it, but four other people whose experience gets affected by others leaving. There is nothing the devs can do for you.
