Go and make your voice heard on steam and write a review. I think that and restrict your usage of the Frontier store is a good option to make your voice heard. I have not experienced the scale issue in my Vive nor any of my friends who own a Vive of their own or tried my Vive. The AA problem is there but is very limited if you have a 1080.
I'm making my voice hopefully at least read by posting on this forum

At least I hope. Plus my wallet decision. The main problem with scale I and many other (in this thread alone and in support tickets in the past) have is that our "virtual bodies" look like we were 12 year olds and everything in the game looks oddly small. Like I wouldn't be able to walk through a door without crouching ect... I don't experience the same size issues in other games or when I run test levels I make in Unreal or Unity, so there is something odd happening. I'm also aware that some people don't seem to notice the issue or it simply isn't there in their case due to IPD differences. I've tried changing IPD on the headseat, but it is no help as my factual IPD is 65 (tested by optician for my glass prescription), so setting anything else is futile and waste of time. The AA problem is fixable very well without using SS 2x if Frontier do their job and provide proper AA and make sure that their rendering pipeline is setup correctly for Vive.
Posting a review is one thing, but this thread has been made by Frontier and that is why I will keep posting here until somebody in FD comes up with a solution or tells us that they don't give a damn about Vive and are going to leave it as is with shoddy pipeline/mipmaps/AA issues/Scaling issues for different IPD ect.... Using Brute force (GTX 1080 or higher) is the least elegant way to solve this issue and it doesn't solve all of them, but just few, so hence my posts here.
On a side note - my partner has 20/20 vision and has Vive of his own and he simply stopped playing ED due to low quality support and the scaling issue. He is a 3d game artist and simply couldn't stomach all the issues (poor quality) of the Vive support, just as a side note.
Plus I have to be honest that I would not be posting here if I didn't want the game to live up to it's potential. I love the potential of this game and I do like some of the improvements in the recent patches of Horizons. I'm simply very frustrated with the Vive support and the absolute abominable lack of communication. This has slowly lead to none of my friends playing ED in VR any more..... Once I've tried playing ED in VR after 4 months break from the Game I finally saw how cool the potential was, but sadly it is being shredded for Vive users by lack of info, fixes and updates by FD.
I remember when DB said how Vive was the superior experience in FD... I've pre-ordered Vive the same day. Then I got shafted by FD and DB as they never bothered to truly optimize the game. Hence my resolute frustration with FD and their way of handling this issue.
