I guess, the only viable solution is to use Screen Percentage around 200-230.
Made an ingame slider that changes this value, and it kinda works… But strangely. On windows standalone/build it behaves as expected(on vive). On Android it does weird stuff with the right eye - when you change this value you get a random chance the right eye will black out, or begin to flicker. If you change value again, there will be chance it’ll repair itself. After 250 flickering is occuring 100% of times and if you go back, it won’t stop.
I hope it’ll be fixed in 19 with the new pixel density system. Haven’t checked it yet.
