Issue ID




Editor crashes with out of memory while importing a lot of assets (mostly textures) at once, on Windows/DX11

Asset - Database


The issue seems to be that during a texture import, video memory usage keeps on rising, eventually runs out of GPU VRAM, starts to use system memory, and eventually can run out of that too. Seems specific to Windows & DX11 graphics API.

How to reproduce:
1. Open the attached project

Reproducible with: 2018.4.33f1, 2019.4.24f1, 2020.3.1f1, 2021.1.0b12, 2021.2.0a10

- The textures inside the project generate a 20+GB Library folder
- The project opens without a crash when opening it again

    Still happening in 2020.3.20 DX12:

    Updating a project from 2020.3.16 DX12 crashes with "out of memory" (15GB+ Working Set, 38GB+ Private Bytes) and never finishes update.

    Would love for this fixed issue to actually be in the version it is claiming it to be fixed for.

    Why can't we vote on this? It's still not marked as resolved for several versions. Is there any ETA on when those will be fixed?

    We are all also seeing this on DX 12 also just to add some input on this.
