UPDATE: Changing this bug to track HDRP performance problem. Universal RP performance bug is being tracked in related case 1158037 which should be fixed when PR 98447 is merged. Also flagging this case as Public.

UPDATE: Changing this bug again to track HDRP performance problem with Stereo Instancing, which will be fixed when PR 5417 lands. Even with this fix I still see bad performance with HDRP in Multi Pass stereo, possibly related to culling. I'll investigate and file a separate bug if needed.

Using HDRP, LWRP, or built-in rendering pipelines, built players on Rift are running at 60 fps using vsync with even a simple scene. Disabling vsync gives 85 - 90 fps, depending on which rendering pipeline is used.

With HDRP, Playmode performance in the Editor is higher than built player performance.

See "Case posted to website" section of this bug report for details specific to HDRP, and comments for follow-up testing on the other rendering pipelines.
