20 and up is all great for me. Sometimes I get 17 and it still plays fine. The only issue is that less than that and I can tell the drag when you move around. Strangely enough a couple of times now, I noticed that in a powered down settlement, it's fine until I power it up. After the power is on, suddenly it's laggy. Makes combat difficult.I see people on here complaining that they only get 60 fps....... if you turned your counter off would you even know? What can the human eye discern?
Now, I am only getting 20 fps and I can sure as hell discern that - it runs like a dog.
