It seems to me that UE4 does not see the difference between vive and vive pro and therefore gives me a small-resolution image on the my hmd.
so I want to increase the resolution manually through “vr.PixelDensity”.
vr.PixelDensity 1 - is not suitable for vive pro.
HTC vive 2160х1200 = 2592000px
HTC vive pro 2880x1600 = 4608000px
I think that vr.PixelDensity for pro = 4608000px / 2592000px = 1,7778
