Regression

Yes

Meta Quest performance loss between URP versions when built

--

-

Reproduction steps:

# Open the user’s attached project “QuestURPPerf2020.zip”
# Enable the Metrics HUD in ODH to see App GPU Time and GPU Utilization
# Build and run on Quest device

Expected result: App Time and GPU Utilization are around the same between different Editor versions
Actual result: App Time and GPU Utilization increase on newer streams

Results:
Version - GPU Utilization - App Time
10.10.0 (2020.3.39f1) - 70% - 8823
12.1.7 (2021.3.10f1) - 75% - 5486
13.1.7 (2022.1.0b16) - 75% - 6046
13.1.8 (2022.1.0f1) - 76% - 8203
13.1.8 (2022.1.17f1) - 76% - 8823
14.0.3 (2022.2.0b8) - 75% - 8191
15.0.1 (2023.1.0a10) - 69% - 8007

Reproducible with devices:
VLNQA00379, Oculus (Quest 2), Android 10, CPU: Snapdragon XR2, GPU: A.3dreno (TM) 650

Reproduced on: Windows 10 Pro 21H2

Notes:

* With a more complex scene, GPU usage skyrockets and is unusable

  1. Resolution Note (fix version 2023.1.0b4):

    - Prevent URP from using Depth32Stencil8 for its intermediate depth texture on Android.

  2. Resolution Note (fix version 2022.2.0b15):

    GPU ultilization is the same and app time is within expectations.

  3. Resolution Note (fix version 2021.3.14f1):

    Performace is back to more expected results for App Time and GPU Utilization

    I think my team is gonna head to unreal as well if this doesn't get fixed. Your also going to lose allot of vr devs as well, since quest 2 is one of the more popular vr sets out there.

    VR is one of the few bastion areas against UE's lumen and nanite, hopefully Unity prioritizes this kind of thing more.

    With VR becoming such an important technology, this should be a huge priority if they want people to stick to this game engine, you never know where the butterfly effect can lead the future!

    This is sad, if this continues, me and our team will switch to Unreal Engine.

    Can confirm performance downgrades, especially in larger scenes
