Vulkan

-

Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/IndirectScene.unity” Scene
3. Switch to Android Platform
4. Build and Run on Quest
5. Open Meta Quest Developer Hub
6. Open the Performance Analyzer tab
7. Enable Performance Analyzer
8. Observe that the Frame Rate is at 72
9. In Editor, add Vulkan Graphics API and remove OpenGLES3 (Edit > Project Settings > Player > Other Settings > Graphics API)
10. Repeat the 4 - 7 steps

Expected result: Frame Rate is constantly at 72
Actual result: Frame Rate gets below 60

  1. Resolution Note:

    The project is not compatible with Unity versions after 2022.3, so we cannot reproduce the performance problem.
    We also think it's unlikely that the performance issue is caused by the engine.
