I have vorpx, just got it today, trying it with diablo III reaper of souls first.
hooks in fine, loads on oculus rift CV1. However, the main screen has a black column running down the middle of it where the content should be. Using each eye independently it seems to be missing a fairly rectangular black area in each eye that overlaps. If I load a menu it goes away or really disappears behind menu, so it’s just the main screen that seems to have this problem. Menus load appropriately in the same center of the screen where content is missing otherwise.
You need to press the Del key and change the 3d settings. There is one setting in particular that will adjust that black bar. Keep extending it until it moves completely off the screen. You will also want to adjust the HUD depth and scale until it looks right.
