Android VR aliasing problem

App for Android VR, FullHD display.
Tryed all sorts of smoothing and other staf. Close to 4+, away - all bad.

Do you have some quality improvement methods.
My idea to make a blur based on distance from character, but can not find how to implement it on a mobile platform.
P. s not the VR version with antialiasing, all is well .

Used MobileHDR + TempolarAA + r.PostProcessAAQuality 6 + r.MobileContentScaleFactor = 0 (the native resolution). And building on Vulkan.

I would be grateful for any advice and constructive criticism adequately.

Can you share the QR code of your VR headset?
