    Hi there,

    I've been testing both HDRP and UWRP on a HP Z Series with a Nvidia Quadro P5000 and Intel I7.

    However, also using Unity's demo Alchemy Lab VR, I have on build done only (Non-stable) 60 fps.
    So, I think that if on a very little project like Alchemy Lab VR, we have lagging and poor fps, on a bigger project with much more interation and objects the fps will be like 20-40.

    In the end, my question is: HDRP (at it 7.2 ver) is still not ready to handle big project in VR?

    Thanks!

    Thanks Peter77, I alredy knew about UWRP, but it has a lot of missing features.
    However I decided to go for UWRP and find a work around for the things that are missing.

    I just recently started testing HDRP or URP for our upcoming project. and it looks like with VR, HDRP is still very unstable. The FPS can be quite low with a relatively empty scene. also single pass instance seems to work and then not work sometime. It looks like URP is still the way forward for now.

    I was wondering, by "missing features", what were you referring to? Like volumetric lights and fog?

    Hi, Did you ever figure this out?

    This is my concern too, not only that, even on an empty scene, I am getting like 7ms-9ms (vs 2ms solid/stable on URP).

    I posted question similar to yours here:https://forum.unity.com/threads/vr-and-hdrp-pc-what-do-need-to-know.916379/#post-6003578

    Still avoiding HDRP and keep using SRP or UWRP with custom effects or shader to achieve realistic results in VR. I think there is a bad development behind HDRP, something messed up with the render pipeline, in particular on Virtual Reality.
