[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 ""
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

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

    I agree it is not fixed

    I need to double-down on what 'AvatarJoe' just commented. When building and running our project on Quest 2 using Unity 2021.3.17f1 & 2021.3.28f1 with Oculus legacy backend, the performance is way better than with OpenXR and latest Unity 2022.3.11f1. We already tested Unity 2022.3.8f1, 2022.3.9f1, 2022.3.10f1 and now 2022.3.11f1 and cannot feel any improvement with 2022.3.11f1 when it comes to CPU load.

    After migrating the project from Unity 2021.3.14f1, I can confirm that it is not "Fixed" in Unity 2022.3.11f1. Although the OVRMetrics are giving me the same average fps and stale frame rates, it seems to be exhibiting worse performance in regards to the CPU. Disappointed in these results after the initial excitement. Just had to order the Quest 3.

    This bug is not fixed in 2023
    please, Unity, fix

    According to my (I am the one submitting this issue) most recent tests, performance between 2020 and 2023 is within a few %. You do need to tweak the URP settings if you upgrade, but this is good news.

    This means that if you have a performance issue, file a bug report!

    have this issue been fixed? Unity is really bad on fixed-release notes atm.

    Got new tests in, the situation seems to have massively improved:

    If your project has performance regressions make bug reports!
    I never tested in 2019, and you might use different features, so make reports so the issues can be fixed!
    Just commenting here does not help that much

    "Under Consideration for 2021.3.X, 2022.2.X, 2023.1.X, 2023.2.X"

    It's alarming how the best version of Unity to use on Quest 2 and 3 is 2019. With Meta no longer supporting 2020 in v55 we're in a situation I never imagined: why have a 20% perf increase, when you will lose 20-40% when upgrading Unity.

    Upgrading a production project to 2023.3 is just not viable today and won't be for years. I respect this URP bug may be challenging, but stating this is 'under consideration' says quite a bit.

    20-40% sounds similar to what I experienced when I went from 2019 to 2021. However, I was able to reclaim the noticeable decrease in performance after I used RenderDoc to discover that I was getting a final blit at the end of each frame. This was being caused by my renderer asset having post effects enabled, and under "Compatibility" "Intermediate Texture" was set to "Always", which means it renders to an intermediate texture and must perform a blit at the end, which is slow on Quest.
