The point that is worth noting is that functionally the game is excellent. I put about 200hrs into it and look forwards to going back to it on release. Performance needs serious work, but I could play it maxed out at a reliable 30-40fps on my 980ti. I can tweak it to run smoother at lower settings, but it looks really nice at full whack. Optimisation is less of a priority to the devs than getting all of the content implemented and getting the gameplay right. The performance will come with time, but the devs are updating the game daily so I wouldn't call them "shoddy"
