DirectX12

-

How to reproduce:
1. Open project "Case_1228854" from the attached link
2. In the Project Window open the folder "previs"
3. Select all Assets in the folder, right-click them and click on "Reimport"
4. After they finish reimporting, reimport them again

Reproducible with: 7.2.0 (2020.2.0a7), 7.3.1 (2020.2.0a7), 8.0.1 (2020.1.0b5, 2020.2.0a7), preview.13 - 9.0.0 (2020.1.0b5, 2020.2.0a7)
Not reproducible with: 7.1.8 (2020.2.0a7), 7.3.1 (2019.3.7f1)
Could not test with: 2017.4.39f1 (Package manager not available), 2018.4.21f1 (HDRP not available in Package Manager)

0x00007FF6D0789DFA (Unity) TiledTextureManager::CheckMemoryBudgetAndUpdateTiledResources

Notes:
1. Only reproduces with HDRP + DXR
2. Importing the entire folder seems to not reproduce the issue
3. Sometimes the issue does not reproduce, reimporting again, or reopening the project makes the issue reproduce again

  1. Resolution Note (fix version 2020.2):

    Fixed in: 2020.2.0a20

    2020.1 and older have a memory usage spike when importing assets with DX12. Newer 2020.2 and above don't have this issue.
