FrameTimingManager.GetLatestTimings returns a smaller gpuFrameTime than it actually is
Reproduction steps:
1. Open the user's attached project ("TimingsRendering.zip")
2. Open the repro scene ("SampleScene")
3. Enter Play Mode
4. Inspect GPU frame time in the upper left corner
Expected result: GPU frame time reflects actual GPU time (~30ms)
Actual result: GPU frame time displays tiny values (~0.02ms)
Reproducible with: 2019.4.10f1, 2020.1.5f1, 2020.2.0b2
Couldn't reproduce with 2018.4 (errors after downgrade)
Notes:
1. The issue also reproduces on builds - real values can be inspected by attaching Profiler to the build
2. To profile GPU times in Editor, switch the Graphics API from Vulkan to Directx11
3. Builds made with Vulkan crashes on launch on 2019.4, 2020.1 streams
