Reproduction steps:
1. Open the attached “Repro” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. Make sure the “Graphics API for Windows” is set to “Direct3D11” by dragging it to the top of the list (Edit > Project Settings > Player > Other Settings > Rendering)
4. Build And Run the project (File > Build And Run)
5. Observe the GPU and CPU time in the Player

Expected result: GPU time is noticeably lower than CPU time (using 60 Hz monitor: GPU time is ~1 ms and CPU time is ~16.66 ms)
Actual result: GPU time is +- equal to the CPU time (using 60 Hz monitor: GPU time is ~16.66 ms and CPU time is ~16.66 ms)

Reproducible with: 2022.3.7f1, 2023.1.9f1, 2023.2.0b5
Couldn’t test with: 2021.3.29f1 (The FrameTimingManager reports CPU and GPU times as 0 when using DX11)

Reproducible on: Windows 10 Pro (22H2)
Not reproducible on: No other environment tested

Note:
- “VSync Count” has to be set to “Every V Blank” for the reproduction (Edit > Project Settings > Quality > Rendering)
- The issue is only reproducible on Direct3D11, on Direct3D12 the reported GPU time is 1ms (as expected)
