I was able to get The Witness running flawlessly with DXVK 0.60 under lutris by following the instructions on the github wiki and literally changing 0.52 to 0.60. I tried to publish this in a new installer, but when I save the dxvk version as 0.60, and then go to view the installer, it appears as null. Editing it back to 0.60 does not save that change. What am I doing wrong here?
