Despite how long the game has been out it's still a broken. It also seems like the devs are focused on the sequel and have left this one so there's not much hope for fixes. Just starting the game I had issues with running the game with dual monitors and had to force it to run in dx12 to get it to stop hopping monitors constantly. Then was hit with huge frame drops randomly and the final straw was stealth killing an enemy only to be glitched into the floor unable to move.
