Then this issue should be investigated. If you get more aliasing with default VR template than there should be something is off. As Recus says it’s only affecting the VR render as the editor viewport is flicker free, even with camera moving.
Maybe as he said, subpixel jitter function by TAA or something similar? We can’t use masked materials at all, even with alpha to coverage enabled, even if we sharpen alpha to coverage. Mip biasing doesn’t work, no matter how aggressive you are, it still flickers. This effectively forces us to use translucent for everything which is just right out bad.
