Is PCVR possible with HDRP?

Unity Engine

Now that HDRP has improved a lot, its it possible to use HDRP for PC VR?

Has anyone successfully done this, or is it better to stick with URP?

Project I have will be PC (none-VR) and PCVR. I would like to use HDRP since it gives much better visual quality for PC(None-vr). I was hoping, I can lower settings all the way down and use for VR. Not to mention, people with 3000 series cards can get high quality graphics with VR too.

Any thoughts?

Thank you!

I’m using HDRP in my VR projects for years, it works quite well if your scene and hdrp asset is properly optimized.

Same here, using HDRP / VR since 2020, works pretty well, but performance is something to keep always in mind.

I’m using HDRP with HTC Vive and Oculus Quest2. Works pretty well.

Thank you all so much for chiming in, I spent months searching and it looked like no one is using HDRP with PCVR.

Are you all getting <11 m/s on your target video card? If so do you mind telling me what your card is?

I did bunch of tests on HDRP at low settings (I could have done this completely wrong, I am new to HDRP, been using URP all this time) and I can barely hold 11m/s on a mostly open world with only a terrain. This was on a GTX 1080.

Same exact scene on URP I was getting <6m/s.

Also are you using Forward or Differed rendering? And do you have any pointers for VR related optimizations?

Thanks again.

Use as less Post Processing as possible. I am using Forward renderer, and I don’t use many lights.
We offer FSR and DLSS to our users to speed things up, but DLSS is somehow broken, only working “sometimes”.
I guess besides this you should do usual optimizations, keep vertex count relatively low, be careful with expensive stuff like Shadows, Transparency, SSS, …
