QualitySettings.streamingMipmapsMemoryBudget is always clamped down to 4096 MB even on 64-bit systems

Graphics - General



Priority: 7Not yet prioritized for a release


Severity: 3Secondary functionality broken

How to reproduce:
1. Open the attached project "case_1147394-TextureStreamingLimit" and scene "SampleScene"
2. Ener Play Mode
3. Observe Console Window output

Expected result: "Actual Budget" and "Target Budget" are both at 4500 MB
Actual result: "Actual Budget" is 4096 MB even though "Target Budget" is 4500 MB

Reproducible with: 2018.3.14f1, 2019.1.0f2, 2019.2.0a13
Could not test with: 2017.4.26f1 (no texture streaming)

Note: the script Component "TextureBudgetAllocation.cs" attached to "MainCamera" tries to set QualitySettings.streamingMipmapsMemoryBudget to 4500 MB but cannot go over 4096. If there is no output in the Console Window after entering Play Mode, make sure that Texture Streaming is enabled in the Quality Settings
