Oh yeah the optimization is pretty terrible, it would be dumb to compare it to a finished triple A game like Darksouls 3. Turning the graphics down helps improve it.
Got really pissed off at the game today when I spent a while collecting materials to make a new bag and when I crafted it, I didn't get the bag. Asked in chat and someone said its bugged :'( Wish they put up a developer note on the crafting panel.
