I ended up buying Moss for the Vive last night, and I think it certain has its pros and cons on the Vive. While the game defaults to a low graphical setting, which looks a lot like the quality on the PS VR, I was able to turn it up to a higher setting, which looks much, much better. It also seems that the weird, speckled-black screens that I disliked on the PS VR variant are part of the game. I really wish they wouldn't use them as it's really jarring to go from a black pre-game loading screen to the aforementioned speckled screen. Although, I think the biggest black mark against Moss on the Vive has to be the controls -- they just aren't that good. Movement is performed on the left trackpad, which is a bit clunky, and jump and attack are bound to separate sides of the right trackpad. It's just kind of awkward and makes me hope that the Knuckles controllers, which have a joystick and actual buttons, will work a lot better.
Although, I noticed a problem last night while playing Moss, and it's safe to say that it was more jarring than that dastardly, speckled screen. What would happen is that I'd be playing, and all of a sudden, the entire game world disappears, and all I see is the wireframe of the play area with the panel displaying the current game. (This is the screen you see before the game loads.) This would usually only happen for a second before the game world popped back in. I didn't notice it occur when doing something in particular. In other words, it wasn't on a certain input or movement. I would've expected it to be the Wireless Adapter, but if I was having transmission issues, I'd expect to see nothing. At first, I wasn't sure if it was a Moss issue, but I swear I saw it happen once during Beat Saber too. Moss is likely graphically more intense compared to Beat Saber, and I don't know if it's an issue with that. My VR machine is an i7-8700k + 1080 Ti, so while I've heard that the Wireless Adapter is a resource hog, I suspect that I'd be okay.
