[XR] ParticleSystem.ScheduleGeometryJobs takes up to ~60% of time when using Render to texture

XR SDK

-

Reproduction steps:
1. Open the attached project ("Heat sources PoC.zip")
2. Open "Handheld Test"
3. Open Profiler window
4. Enter Play mode
5. Search for "ParticleSystem.ScheduleGeometryJobs" in Profiler

Expected result: ParticleSystem.ScheduleGeometryJobs performance is similar to non-XR or XR SDK
Actual result: ParticleSystem.ScheduleGeometryJobs takes up to ~60% of the time

Reproducible with: 2018.4.28f1, 2019.4.12f1 (legacy XR)
Not reproducible with: 2020.1.8f1, 2020.2.0b6 (XR SDK)

Tested with:
- Oculus Rift (Oculus SDK, OpenVR SDK)
- MockHMD (ParticleSystem.ScheduleGeometryJobs spikes up to ~60%)

  1. Resolution Note (2019.4.X):

    As this relates to the now deprecated legacy VR management system (which has been replaced by the XR Management package), and that it uses the OpenVR SDK (which Valve supports; not Unity), resolving this issue as Won't Fix.
