Yeah, it would run badly because if the PC isn't built to run it - it will have issues running it.
Like mine's not made to run it, but it runs it okay.
All my settings are very low and it doesn't look as good and it's still freezy, laggy and janky.
I don't want to keep playing like that - it hinders me.
Imagine chasing someone and your game just stutters constantly.
Can't catch up to them, can't see where they went, lose the chase, waste all your time game over.
Imagine running from the Killer and not being able to get away because of the constant freezing and lagging.
It's not fluid and smooth - its coarse and rough.
I want to play on a PC where it's fluid and smooth.
