[URP][XR] Performance degradation when comparing Android Quest 2 builds across 2020.3 and 2023.x

--

-

Steps to reproduce:
1. Open the attached user's project "PerfTest2020.zip"
2. Build the project to Quest 2 in 2020.3.47f1
3. Observe performance via OVRMetrics (GPU usage and stalled frames)
4. Build the project in 2023.1.0b12
5. Observe performance via OVRMetrics (GPU usage and stalled frames)

Expected results: performance is mostly the same across Unity versions on a Quest 2 with the same Scenes
Actual Results: performance degrades when building to Quest 2 in 2022.2 and above

Reproducible with: URP 10.10.1 - 16.0.1 (2020.3.47f1, 2021.3.22f1, 2022.2.15f1, 2023.1.0b12, 2023.2.0a10)

Reproducible with these devices:
VLNQA00415 - Oculus Quest 2 (Quest 2), CPU: Snapdragon XR2, GPU: Adreno 650, OS: 10
User devices:
Pico 4

Environment: Windows 10 22H2

Notes:
-Testing results are attached "IN-31610 performance results"
-Tested with OpenXR and OculusXR XR plugins, using different Render Modes, OpenGLES3 and Vulkan

    This reply does not answer at all the big decrease of performance from 2020 to 2021.

    Dissapointed to see this reply.
    while this might explain 2021 vs 2022, this does not explain the drastic difference between 2022 and 2023.
    Will report more in july...

    The engine of choice for VR content, actively ignoring the most critical problem it has with VR content.

    Pretty sure that they wont fix it, they will wait until Meta Quest 3 launches so it mitigates the problem because it's more powerful

    Yes, same, still - it's been an issue for ever, thanks DEVDUNK for reporting this again and again - I noticed it's now at least in KNOWN ISSUES for 2021.3.24.

    Same here, I'm stuck on 2020 because my Quest 2 game performs very poorly on anything newer. Arguably, 2019 performed even better than 2020, but I'm unable to go back.

    This has been an ongoing, well observed issue that many developers in the quest 2 development community have tried to report on, and been pressing to have fixed for quite some time. There’s a lot of changes and improvements to the engine and to urp that most of us have to miss out on because to use the latest version of unity is to have a game that won’t run on the quest 2. It’s very disappointing for version updates to outright make a specific platform unusable. Even more so when indie vr devs whose games haven’t even released to be harassed to pay for the pro license for an engine who’s latest version we can’t even use.

    Here are some other smaller issues that are relevant to VR performance as well:
    Input system optimizations performing worse in VR: https://issuetracker.unity3d.com/issues/input-system-enabling-both-optimization-options-of-input-system-reduces-performance-in-built-players
    OculusXR performing worse than OpenXR: https://issuetracker.unity3d.com/issues/quest-2-oculusxr-has-worse-performance-than-openxr-when-built
