Without these features enabled, developing for VR causes a massive performance cost on even high end machines and then you also want to be seeing complex rendering features like volumetrics and fluid sim. In addition to the lack of volumetrics (not a problem in 4.25, but still has a huge performance cost) Ive noticed translucent materials simply not appearing in one eye and controls for Reverb G2 being broken (might work with HP’s plugin, but for 4.26 only? Come off it HP).
Just put a pin in 4.26, its broken for VR.
